Typical electric wheelchairs usually cost around 2,500$, and while it could turn around the life of whoever needs it, not everyone can justify spending such a grand amount of money, and are left stuck with rented wheelchairs. Our kit connects to standard rented wheelchairs without damaging them at that slightest and makes them mobile in a simplistic manner, for a fraction of the price, around 500$.
While every part of our kit can be bought separately, and be assembled using the tools in your disposal and a 3D printer, this kit has the added bonus of being comprised of parts which are abundant with every FRC team worldwide, meaning your local FRC team would be able to assemble your newly fashioned wheelchair.
All printed parts are recommended to have 15-35% infill.
~1.2mm Shell thickness
~1.2mm Bottom/Top thickness
Recommended printing material Apex PLA++ by Breathe-3DP although normal PLA and ABS do function with higher infill.

How I Designed This
How we designed this:
We had a small group of 3 people work on the kit, each with a unique abilities and skills.
Yuval Dascalu - Project manager and Mechanics expert. Solidworks 2017 for designing. Past experience from Robotics competitions and projects.
Roee Bar-Yadin - Electronics expert, Past experience from Robotics competitions. Head of Electronics department
Tomer Bitan - Programming expert, working with Arduino Uno. Past experience from Robotics competitions and knowledge previously gained at school.
Team 1577, for giving us a roof over our heads and all the tools we ever needed.
Team 1577's mentors, for giving us the idea and assistance along the way.
Team 1577's sponsor, for sustaining our team for years through all our projects.
Daniel Shani, for the tough tapping required.
Ben Arbib, for being a perfect model for the video.
Esquilo Thingiverse user, for the Arduino snug case.
The team 1577 was founded in 2005 by its first mentor, Eyal Hershko, who brought the FRC to Israel for the first time.
Our team was one of the 12 first teams to compete in the Israeli Regional, and since then we continued competing for the last 10 years. We have a long heritage of professionalism, Persistence and the strive to be better as a team and as individuals.
Up to now, our team has included over 150 students that each has left their own unique mark and helped to build and design the nature of our team as we know it today.
Our team includes 31 high school members and 3 mentors that lead us and guide us based on their knowledge and experience. We learn from each other and from professionals that come in their free time to help and teach us in different subjects such as mechanics, programing, electronics, CAD, and strategy.
The specific team which worked on this kit consists of 3 students, each with their own distinct skills and expertise, such as Mechanics, Electronics and Programming, but we all had part in the general planning of the kit and we all helped each other in any way we could.
Over the span of a few weeks we have had frequent meetings, most of them at our own houses and during our own personal time.
During those couple of weeks we have had roughly 5 designs and 3 working prototypes, with totally different mechanics behind each idea.
