Engineering
- Invented and built the quick-release attachment and the dual-motor friction drive that powers the wheelchair's own tires.
- Wrote the C++ firmware: real-time control loops, joystick input, USB serial communication between controller and drive unit, failsafes, and watchdogs.
- Closed the loop with motor encoders and an IMU for smooth acceleration and straight-line tracking.
- Designed the controller and main electronics PCBs.
