Our departmental competition winning video: What is Engineering?
Watch the video on Vimeo.
The competition brief

We were asked to create a short, educational video to inform school children of what engineering is. Which is important because engineering isn’t something which is taught in schools, so there is not much awareness of it. There wasn’t much else that was specified so there was quite a lot of freedom in what we could do, which benefited us as a group. We gelled from the start, we all get on. Having the tutor meetings helped to get everyone together. If we’d have had different ideas of what to do then it might have been harder, but we all wanted to get it done as quickly and simply as possible, and it just fell into place.

Developing our concept

We made an online group chat so everyone knew what was going on all the time. This meant we could do our bits without all meeting together at the same time, which was a lot more convenient. We researched some stuff beforehand, different points of view on engineering.  It helped a lot that we had similar ideas of what we wanted to do.  We all agreed early on that nobody wanted to be standing in front of the camera and talking. So we decided to narrate over drawings, illustrating our idea of what engineering is, and Katie’s drawing skills were excellent. We planned it as a group and then gave each of us a role - it was like a production line. It was a fairly quick process in the end.

The best bit

When we watched it for the first time – seeing the finished product was definitely the most enjoyable part of the project. We’d all done different bits so it was good to see it all come together.  It was also great winning the competition, though we groaned when we realised we would have to go up on stage to receive it.

Our top tips for next year entrants

Try and do something different, to grab the attention of whoever’s watching. Make it stand out. Something unique. And don’t overstress it – keep it simple. It’s the first couple of weeks of university when there are lots of things going on, so don’t make it the be all and end all, just have fun doing it.

 

Bringing engineering to the Basil Spence project

Author: Zach Wynne


The 2016 Basil Spence brief

  • To evoke in visitor, user and designer the mystique and splendour of the railway station as a building type.
  • To use the station as a catalyst in the renewal (both physical and social) of the part of Oxford in which it sits.
  • To amplify the possibilities of station as a typology.
  • To foster a thoughtful and mutually respectful integration of the disciplines of engineering and architecture in order to achieve the above.

Our winning design

Our winning design for the Basil Spence project evolved naturally from our initial idea, that our station building should be a celebration of Oxford's literary heritage. We took the elements that were strong, that we believed were the core of our design and we refined and strengthened them, allowing the ideas to change naturally. At the same time we were ruthless when something felt like it didn't work, it was radically altered, no matter how long we'd spent working on it.

We agreed at the beginning of the project that this was our chance to do something bold and radical with both the architecture and engineering.

Overcoming design challenges in multidisciplinary teams

It was wonderful to see how different people with different specialties approached the same design challenges. This allowed the design to be fully integrated right from the start as people could identify issues early on, allowing them to be addressed in the design process and not worked around later in the project. It exposed me to new ideas and allowed me to work with a group of architects who were all wonderful, talented and patient people.

The project allowed me to develop my ability to work as part of a multidisciplinary team and to come up with radical solutions to challenging problems that encompassed not only innovative and honest engineering, but fitted with the architectural intent of the project and added to the overall scheme. I also had the opportunity to experience the wonders and heartbreaks involved with casting concrete and plaster architectural models.

A perfect culmination to my university education

“I could tell you my adventures—beginning from this morning,” said Alice a little timidly; “but it’s no use going back to yesterday, because I was a different person then.”― Lewis Carroll

This project has allowed me to delve into fields of research I never believed I would encounter; I have learnt the life cycle patterns of the endangered Euphydryas Aurinia butterfly, provided preliminary designs on a drainage system based on medieval agricultural earth works and been given the freedom to explore and provide feasible design work in areas outside of my comfort zone. I've been able to push the envelope of what was thought possible.

The beauty of this project is the removal of boundaries, to be encouraged to explore avenues which have thus far remained closed and which may never open again. I am proud of the work presented in this project. I believe it represents a perfect culmination to my university education, a summation of all work undertake in four and a half long years.

A civil engineer working with architects

My heartfelt gratitude to my architects; Matt McClusky, Emma Moberg and Helen Needs, for their undying patience and support. Most of all I would like to thank them for treating me as an equal in all aspects of the project; whether architectural precedent, scale modelling or design integration. I have never worked with a group of people who were as wonderful, caring and gifted. They made the long hours which this project entailed not only bearable but enjoyable.

 

Heading Moonward

  , , ,

📥  Department of Mechanical Engineering, Student projects, Undergraduate

What is the first thing that comes to ones' mind when you think of going to the moon? Reminiscent memories of the monstrous Saturn 5 rockets used to take the Apollo astronauts to our closest celestial neighbour perhaps? Or fantastical ideas of far-fetched future technology ferrying people back and forth in ease and comfort? A visionary space technology start-up in India has their own ideas, and are acting upon them, planning to send a robotic spacecraft to the moon in late 2017, depositing a rover and multiple other scientific payloads on the lunar surface.

Team Indus are a passionate team of driven aerospace engineers based in Bangalore who are taking part in the Google Lunar Xprize, an international competition challenging private companies around the world to land a spacecraft on the moon, deposit a rover that travels at least 500m and sends back to earth high-definition video and pictures. The first team to do so will be given a prize of US$30 million. As part of their planned mission, the company has left a little (and I mean little) room for extra payload. This is where Lab2Moon comes in.

The Lab2Moon challenge

Lab2Moon is another international competition hosted by Team Indus to pit the best student minds worldwide against each other to innovate, design and build an experimental payload that will aid the development of sustainable human presence on the moon. 3000 teams sent in their concepts. 25 were selected to advance to the next stage, where they will be flown out to Bangalore and will present prototypes to a board of judges. 'LunaDome' is three University of Bath aerospace students' entry to the competition, and is in the second round as one of the 25. If it wins the second round, we will have the opportunity to put our designed experiment onto a spacecraft and see it placed on the lunar surface.

Our LunaDome project

Effectively, 'LunaDome' aims to understand the effect of temperature fluctuations experienced on the lunar surface upon a pressure controlled environment. The critical payload specifications state that the experiment has to fit into a space the size of a generic coke can, and weigh no more than 250g. Our design is simple: a compressed CO2 canister will vent CO2 through a bespoke valve, designed and built by us, into a sealed, fixed volume 'dome'. Think shiny inflatable bag. This 'dome' will be filled to atmospheric pressure and controlled so as to maintain this pressure. The temperature variation experienced by the sealed CO2 will be measured and sent back to earth for analysis. The aim is to understand what heating and cooling capacity an environmental control and life support system (an air - con) would have to achieve for a habitable atmosphere on the lunar surface.

Keep track of our progress

This project has opened up a huge opportunity for the University of Bath to showcase its excellent engineering capabilities. We have the privilege of being a part of a movement aimed at inspiring younger generations and getting people excited about space and future technological prospects. Our team has been featured on BBC Radio Bristol and BBC Radio Berkshire, and we have a large social media drive to gain exposure and interest in what we are doing (like our Facebook page, subscribe to our YouTube channel or visit our website). Please do find us, follow us and journey with us as we aim to bring humanity to the moon!

 

Video Production for your Student Project

  , , , , , , , , , , , , , , , , , , , ,

📥  Department of Mechanical Engineering, Student projects, Undergraduate

When people ask what I do, I say that I’m an engineer, completing the second year of my PhD. I work on control systems and simulation, and I want to go into the automotive industry. But in my spare time during my university career, I have developed video production and rendering skills to the point that I’m now earning some income on the side, and I love it! (The income, yes, but also what I do).

I’ve developed these skills gradually throughout a few years, but they’ve really been given a big boost when I joined Team Bath Racing - the Formula Student Racing team – back in 2014. I became business manager for that year, and marketing became a big part of my job. It included branding, media content, and making the team appealing to both students and sponsors. I can write letters, hand out flyers, I can tell you over and over again what makes TBR fantastic, but what I’ve found to be most effective tool is video content. It’s catchy, it’s exciting, and it’s dynamic, just like TBR!

As a result, we have a strong media presence both in the University and in the Formula Student world. If you don't know what Formula Student is, take a look at this fantastic video produced by my good friend and video editing partner Kevin Johnson, who filmed and edited this in one weekend!:

 

So, maybe you’re involved with a University project, and you want the world to know how great it is. Perhaps, like TBR, you need sponsors to survive, and you need to attract them to YOUR project, not the one at University X. Well, let me share my experience from the perspective of someone who is an engineer first, and an amateur video producer second.


PLAN IT!
The first step of video production for your university project is to assemble your V-Team. When you’ve got university deadlines and project timelines to meet, video production becomes much easier with a good team to share the workload and creative process.

The V-team includes stakeholders within the University project who have a say in how the project would be represented to the public. Ours included the project manager, business manager, sponsorship accounts manager, and the video grunts like myself. We sweetened the deal by meeting on a Friday afternoon and going for a crepe in the SU afterwards, so our attendance was usually quite high. If you’re a strong, independent lone wolf who “don’t need no team”, don’t skip this section! This is probably the most crucial phase of the video production process, and one that people rush over most often.

Unified Brand
At your early team meetings, you need to figure out what why you want to make videos, because there’s no point wasting your effort. Before you start filming, start by developing the marketing concept and visual themes for your project. It’s important because it will give your video content a unified approach, building your brand and making it recognisable. Without discussing these themes, your videos will feel disjointed.

Indeed, the outcomes of these meetings will be valid for other areas of engagement, not just your videos; for TBR this included our social media, posters, presentations, events, our apparel, and even the racecar itself! We settled on our team colours of black, white, and BP green, along with the occasional hexagon pattern, and that bled into most areas of our brand for last year.

TBR16

Black, White, BP Green and Hexagon theme, as seen on the TBR16 livery and headrest.

I’ve found coming up with a few key phrases to sum up the marketing campaign helps by making sure each video ultimately meets one or more of these requirements. Last year our three phrases were:

“Professional”

“Creates Loyal Fans”

“Visceral”

Our videos had to reflect these phrases as much as we could creatively manage.

Plan Your Video Content
Now that you have your unified approach figured out, it’s time to make a plan! Think about how many videos you want to (and are able to) produce. Should they coincide with some of your key dates? Who wants to take the lead on each one? In what way will these videos help your project along? You don’t want to end up with a huge video workload at the same time as that coursework you will inevitably procrastinate over until the week before hand-in.

Most of our videos had our big May 25th event in mind – TBR Car Launch. All of our videos pointed towards Car Launch because that is when we would unveil our car for the first time, and we want our fans to be loyal to our team throughout the subsequent race season. It’s also the only time when nearly all of our past and present sponsors travel to Bath to see us, so it has a lot of sponsorship money riding on it.

Once you have a gameplan for which videos you want to release in the year, make a plan for each one!

Who are we trying to reach?” Is it sponsors? Fans? Schoolchildren? Students? This will almost certainly dictate the ‘mood’ of your video.

What are we trying to tell them, or get them to do?” Each video has a purpose, and this needs to be discussed within your brand phrases. Is it to relay information to people who’ve never heard of you? To generate interest of people who have? Pitch a proposal for a sponsor? Set a goal for the video, and possibly write a script.

How do we get them to watch it?” What use is the video if no-one watches it! Think about your distribution plans, and how will you make your video visible to your target audience. This discussion should also branch off into plans for expanding your overall marketing and public engagement strategy, whether it be through social media, the events you attend, flyers around campus etc.  You need to maximise your marketing platform to give your videos the best reach they can.

How do we put it into practice?” One of my tasks was to create a teaser one month before Car Launch to get people excited about it. So I looked back at ‘Professional’ and ‘Visceral’, and created a 360 video that included our colour themes and patterns. Watch it below!

 

Naturally, this is a render and not a filmed and edited piece, but it reflects how those early meetings drive your creativity and innovation.

With your plan ready, it’s time to get filming.


FILM IT!
Filming can be both the most fun and the most frustrating part of the process. It consists of equal parts joy of seeing the video develop before your eyes, and annoyance from not filming that perfect shot you want. But that’s video production for you.

There are plenty of guides on the internet on how to set up a perfect shot written by people much better at this than me, so I won’t waste your time here talking about it, but I will give you a few pointers as someone who’s probably in much the same position as you!

University Library has you covered: If you don’t have a camera, the University Library has some that you can hire out that come with a tripod. Follow this link for more information.

Multiple takes: Film the same shot at least three times from the same angle if you’re able to. Then film the same thing three times from a different angle! This makes editing much easier as you can splice the good bits from each one together, and you end up with a much better video.

Use a tripod: The shaky documentary-style video might be having a resurgence (think Parks and Recreation), but they use special equipment to not make it feel nauseating. The best thing you can do to make your videos not look like a home movie is to use a tripod. If you can get a slider, too, this will make your videos feel much more slick and professional (I’m sure someone in Mech Eng would have fun building one for you).

Use a microphone: If your video is to have any speaking in it, be sure to use an external microphone, not just the built-in one from the camera. Bad audio can ruin a video, usually more so than the visuals can! This link shows you what I mean.

 

Zoom: If like us you have a team member keen on photography who has a DSLR with a zoom lens, be sure to try out a 50mm zoom in some of your shots (strictly speaking it’s a 50mm ‘focal length’). This is the closest to the human eye zoom, and makes the video seem much more natural. Too little zoom and it feels like a home video. Too much and any shakiness gets amplified. For comparison, the new iPhone 7 has a 28mm zoom (again, "focal length"). The video camera from the University Library may also have a zoom function, so give it a try and see what you like.

It takes longer than you think: If you’re in charge of filming a particular video, plan enough time to try the shots you want, and then double it. It takes much longer than you think, and other people involved need to be aware of that. As the old guy in Toy Story 2 said: “you can’t rush art.” Good planning makes the filming activity take twice as long as scheduled, bad planning makes it take much, much longer. Keep that in mind.

One final note, don’t be afraid to get creative! Just be sure to get the shots you feel you need within your timeframe; any extra time allows you to get really creative. A few people may have seen myself and my friend in the car park on Saturday, trying out a wheelchair to get some smooth dynamic shots of our cars… it sort of worked, by the way!


EDIT IT!
As an engineer, I like to tinker. Whether it be my computer code, my car, my electronics, I like to try and explore new ways to make my experience better. Consequently, editing is my favourite part of the video process, as I get to tweak this parameter or animate this gain… plus I get to avoid sunlight like a true engineer.

Pick your poison: After filming, you’ll already have visualised a vague sequence in your mind, and know how you want the video to look. The key is getting good at a chosen editing software to literally make your dreams come true. Difficult software can ruin the experience to the point you get so frustrated that you just say ‘that’ll do’ and end up with a poor video, so choose wisely. Something like Windows Movie Maker just isn’t going to cut it (pun intended), though iMovie is getting better. As a student, you get the benefit of discounts of many editing suites, so I would recommend something like Adobe Premiere. It’s part of a £15/month package, and includes Photoshop, After Effects and loads more Adobe products. Plus you get a free trial! Find out more here.

Again, there are plenty of online guides on editing software and how to use it, so chose an editing suite and get good at googling! However, as before, here are a few pointers to help your process:

Check music royalties: The world of copyright is a minefield, and one where you don’t want to put a foot wrong. Unfortunately, obtaining the rights to a particular song is usually expensive. We wanted to use a Jack Garratt song in one of our videos, but after contacting just the publisher the basic price was £2000! I explained it was for a good cause, but they said that was their ‘charities’ rate. Your best bet is to look for – and likely pay for – ‘royalty free’ music, like the ones found in here. Alternatively, you could compose your own…

Introduce yourselves: Most YouTube channels use some form of creative intro displaying their logo, as does TBR, and so should you! It’s a great way to tie your videos together so that they are recognisable, and lets you draw the viewers in. Think about it – Facebookers scroll through hundreds of videos a week, why would they want to stop and watch yours? You have two seconds to grab their attention. After Effects and Blender are my go-to tools for motion graphics, but you can equally film something for it instead.

Team Feedback: As the old adage goes ‘too many cooks spoil the broth’, and that is certainly true for editing. Ever heard of famous bands splitting because of ‘creative differences’? It’s best not to have multiple people editing a video, as your creative vision gets clouded trying to constantly explain it to a pushy team member. However, you really should approach your V-Team after your first cut, as they will have really good feedback and should offer constructive creative criticism on how to make the video even better! The final cut lays on your lap, but they certainly help you get there.

Here is one of our favourite videos made by Team Bath Racing. It was for a competition here at the University hosted by Women in Engineering to help promote engineering amongst schoolchildren, particularly girls. We won by the way. Because the video wasn’t a classic promo for TBR, we didn’t implement all the marketing-related tips outlined above, but we did follow the general video production process, overall.

 

There you have it! Once you’ve finished your video and your team is happy, get it out there for the world to see.


Closing Remarks
Getting good at video editing is not an overnight event, but it is a skill that is worth every second you put in. It’s easier to learn video editing when you have a project you’re passionate about, like the project you’re involved with at the University. For example, I’ve been learning a rendering program called Blender by doing 3D renders for TBR for the past three years, just because I was passionate about the project. Now, my skill has developed to the point that I’m considering starting up a render and video production business with my friend, as we’ve had many people and companies approach us with paying contracts to produce videos and renders for them!

All this to say, don’t feel like you’re wasting your time being stuck doing editing. It’s a valuable life skill and a creative outlet, so why not take the opportunity to benefit your project while also developing yourself.

If you have any questions or queries, feel free to find me on Person Finder, or pop down to the TBR Buildroom in 4 East and ask around how you can get involved. Please also be sure to like Team Bath Racing on Facebook and follow us on Twitter so you can see the awesome activities we get up to. Look out for news about TBR Car Launch, and find out how you can attend! We have some big plans for this year, stay tuned.

Happy Filming,

Things are about to get electric

  , , , ,

📥  Department of Electronic & Electrical Engineering, Student projects, Undergraduate

Team Bath Racing Electric (TBRe) represents the University at the annual Formula Student Electric competition. We aim to become the top electric team in the UK in 2017 and to set the foundations for continued electric vehicle research and development at the University for many years to come. TBRe was founded approximately a year ago by a small group of final-year engineering students that believed in the importance of electric vehicle technology for the future of sustainable mobility. They were also crazy about racing.

From go-kart to Silverstone in 12 months

The project began with the development of an electric go-kart. Essentially, the aim was to replace the go-kart’s original petrol engine with an electric motor. The success of this project provided a hands-on working knowledge of the electrical systems and proved the feasibility of the team’s wider goal: to develop a fully electric race car in time for the 2016 Formula Student event at Silverstone.

The 12 months that followed were hectic. Time had to be split between setting up the team (i.e. recruitment, funding, sponsorships…) and the development of the car. Many sleepless nights later, the team was able to take TBRe16 to Silverstone in July. The valuable feedback obtained during the event from technical design judges will be incorporated into next year’s car, marking the beginning of a cycle of knowledge transfer that will continue for many years to come! TBRe’s successes in 2016 would not have been possible without the support given by the Faculty of Engineering & Design and Team Bath Racing (TBR) – thank you!

Watch Team Bath Racing Electric in action at Silverstone 2016


Launching our 2016/17 project

Our official 2016/17 launch on the 7th of October marked the beginning of a new era for TBRe. It was a pleasure to inaugurate our brand new build room and present our team, goals and long-term vision to over 70 enthusiastic engineering students that share our enthusiasm for racing and technology. The team has rapidly tripled in size to approximately 30 students from a range of year groups and disciplines, including a dedicated business team that will take care of finance/logistics/media and allow the technical team to focus exclusively on designing TBRe17!

How to get involved

It is hard to explain how thrilled we are about TBRe’s prospects for the future. With a team of highly motivated individuals and continued support from our academic and industrial partners, 2017 is set to be a game-changing year for the project. Follow our Facebook page and come visit us in 2E 1.10 (Department of Electronic & Engineering) if you want to get involved or simply learn more about the team, we look forward to meeting you!

 

Taking to the skies with Human Powered Aircraft

  , , ,

📥  Department of Mechanical Engineering, Student projects, Undergraduate

Author: Lewis Rawlinson, leader of our Bath University Man Powered AirCraft (BUMPAC) team.


In February 2015 seven Aerospace Engineering students were tasked to design a Human Powered Aircraft from scratch. The BUMPAC team designed an innovative aircraft with rigid lift struts and modern composite structure. A year later four of the original members based their final-year engineering projects around HPAs. We came together to revive BUMPAC and continue the work started by HPA teams before us.

Inheriting a skeleton set of wings, a fuselage and a few other components, we set about redesigning and building our aircraft, which would later be christened Angel. I designed and built the drivetrain, as well as taking responsibility for all organisational, admin and logistical tasks for the team. This included dividing jobs, setting deadlines and advising the rest of the team on technical and interface aspects.

Angel’s first flight

In July we took Angel to the airfield for the BHPFC Sywell competition. After fixing damage sustained in transit and waiting for a weather window we attempted our first flight. Unfortunately there were issues with the drivetrain that prevented the propeller from getting to full speed. We anticipated this might be an issue and had already manufactured tensioning devices, but had left these off the aircraft in an attempt to save weight. We fitted our tensioning devices and made a number of adjustments to the aircraft, particularly increasing dihedral and modifying the control system interface.

On the morning of July 20th weather conditions looked perfect. With a slight headwind the team rolled the aircraft out onto the concrete apron, pointed into the wind and started pedalling and pushing hard. Angel leapt six feet into the air taking the whole team by surprise. Unfortunately she then lost a lot of airspeed causing her to stall and come crashing back down a few seconds later. Nevertheless, with this taste of success we set about fixing the damage again and making more adjustments. This time looking for more stability and easier control!

24 hours later Angel flies again

Just 24 hours later the team were back out and ready for more, but with no wind this would be a much harder effort. Lining up again on the concrete apron, pointing out towards plenty of space the props started spinning and the aircraft accelerated, very quickly running out of tarmac and bumping along the grass to a gentle stop. The team rolled her back as far as possible, lined up and went again. This time Angel accelerated more quickly, tapped onto the grass and with a pull of the stick lifted gently into the air. Alarmingly in taking off, she had rolled slightly and started turning right towards the hangars. The pilot (me) pulled off the power, touched down and rolled to a stop. Crisis averted with no damage! We put Angel away for the first time without damage. A very welcome respite.

34 seconds of flight

Throughout the next day we tinkered and rested, eagerly awaiting the evening’s flying. This time the team made their way all the way up to the end of the main runway. When the all clear was given, the props slowly started spinning up, the ground handlers started running, the front wheel lifted off the ground and a few seconds later the rear followed suit. Flying just above the ground Angel swept down the runway gracefully, eventually touching down 34 seconds later. She pulled off the runway and came to a gentle stop, caught by the ground handlers who had been following behind on bicycles. I collapsed to the floor, overwhelmed by the effort and joy of what had been achieved. Angel once again went away unharmed.

Angel's final flight

Dawn broke on the last Saturday of the competition. The controls and cg had been slightly adjusted in the hope of reducing the power requirement and making it easier to take-off. The latter was achieved arguably too successfully. With a slight headwind, Angel set off down the runway under full pilot power, climbed and rolled aggressively, and came back down with an almighty crack. The left wing tip caught the ground and tore the wing from the fuselage, shattering a handful of ribs, destroying the centre section of the wing and tearing the fuselage apart at the base of the chain tube. With that, the competition was all but over for us.

I’m proud of the incredible success that was achieved by just four passionate guys with buckets of enthusiasm. The remains of Angel were packed away and sent back to the University of Bath, in the hope that the next generation will carry her on and make her great once again.

The problem of comfort in prosthetics

  , , , , , , ,

📥  Department of Electronic & Electrical Engineering, Department of Mechanical Engineering, Student projects, Undergraduate

Author: Oscar Rovira (2nd year Integrated Mechanical & Electrical Engineering student).


There are thousands of amputations per year in war-torn countries due to mines. The current process of multiple castings and weeks of testing for every individual prosthetic limb has remained relatively unchanged for fifty years. This is a time consuming and costly process for a standard prosthetic (prices can range from £4000 to £40,000).

3D printing technology is developing prosthetic technology at a reduced price, but there remains comfort and reliability issues. As part of my first-year project I decided to focus on developing affordable, comfortable prosthetics. In the end, no matter how robust a prosthesis is, if it’s not comfortable to wear, then it won't be used.

Developing a prototype

Once I knew my objective, I started drawing and sketching all the ideas that came to my mind: from developing a fully 3D printed design of a robotic leg that could automatically adapt to the limb, to creating a prosthesis which could be “built” by the customer (imagine Lego pieces constructing and improving their design). After two weeks of crazy designs and research I decided that the quickest way to solve the problem of comfort was to create a tool that could analyse the stiffness of the stump at any point. This would reduce the forces that the socket applies to the hard tissue, thus reducing any soreness due to bad force distribution.

Inspired by the FitSocket from MIT, and with the objective of reducing the cost whilst maintaining reliability, I started writing all the specifications that “Rijido” (the name I gave my project) needed. Once I had all the measurements and data I spent three days doing all the CAD designs that I would later 3D print. Once all the parts were printed, I started troubleshooting with the prototype and assembly until I got a much better result. Then I used a solder to attach all the wires to the prototype and I connected an Arduino with a bit of code in order to retrieve all the data. After one month Rijido’s first prototype was born!

Seeking funding and promoting my project

I would say that there’s nothing more fulfilling than to see hard work, passion and dedication finally paying off, but that's not where the story ends. I posted my project on Instructables and I applied to a seed accelerator named Imagine to receive feedback and promote Rijido. Although I didn't receive funding from the seed accelerator in the end, I still managed to finish third out of two hundred applicants.

A prosthetist from South Carolina noticed my project on Instructables and expressed an interest in using Rijido as a tool in his practice. It was so exciting to see that my project was actually something people were already looking for. This prosthetist got in touch with the MIT Department of Biomechanics, which then contacted Arthur Petron, a postgraduate who holds the patent alongside Hugh Herr (a heavily influential person in the area of biomechanics) of FitSocket. It was amazing to talk on LinkedIn with the person (Arthur) who first inspired me. Rijido was also then selected as a finalist for the TEDxBarcelona Awards 2016.

Passion and perseverance

Fun, stress, excitement, uncertainty…I would say that the whole journey of making Rijido was a combination of these emotions. The fact that I could use 3D printers, get spare parts and work both in the mechanical and electrical workshops at any time, was the most fun part. I felt like a kid in a ball pit.

Thanks to Rijido I have learnt a host of things! In terms of technical skills, I have mastered how to use 3D printers, I have developed my skills at using turning machines, drawing, CAD modelling and project management. The project also introduced me to different business strategies. In terms of personal skills, I have gained more confidence in myself and improved my communication skills. I’ve learnt again that the combination of passion and perseverance can make any idea into reality and verified how errors and mistakes during the design process are key to producing a much better final product.

Definitely only one of the many more projects yet to come…
