Robot: Manual to Power Wheel Chair Conversion Kit

Robot Description:

Our project solution is a smart phone controlled power conversion kit that fits the majority of manual wheelchairs. The kit is be easily removable, has a simple initial setup and meets the minimum speed of a walking pace. By being app-controlled, the system does away with the conventional joystick. This adds convenience to the user as they can use their own mobile device or tablet as well as complexity to the project. The product will also not affect the mobility of the manual wheelchair by using a compact design.

3 Key Elements

Android Controlled Via Blue Tooth – Joy Stick App Developed By Badri

  • Acts as a joystick controller to move the wheelchair
  • Based on the finger gesture, the program returns direction, x-coordinate, y-coordinate, and the displacement from the center
  • Bitmap, openGL, and canvas were used to design the joystick
  • A mathematical algorithm was written to ensure the joystick cursor stays within the restricted area

Easily adaptable to many wheelchairs

  • The X-Drive is attached to a bar which slides onto the back of the chair. An industry expert informed us the the “wheelie” bar where the bar slides on is a common standard

Overall the best quality of the X-Drive is its ability to allow a manual wheel chair use to maintain the advantages of a manual wheel chair (ease of transport, weight, low cost) while combining the advantages of powered wheel chair (low body strain, ease of use). It does while keeping the cost low and looking cool.

Third Place Winners:

School: John Polanyi Collegiate, Toronto, ON
Robot: Formulator 3D Printer

Robot Description:

The Formulator 3D printer was developed by expanding the frame, adding a larger base, and a second extruder, of the Makeblock Constructor. Our printer, which cost approximately $1000 to make, has comparable quality in printing as a professional, $25000 printer, and also much more expansion capability. Due to the modular design, and open source Arduino platform, we are able to very cheaply upgrade any part of our printer.
