The story so far, as a changelog. + shipped,- dropped, ~ in progress.
first robot
- + gesture-controlled car (winter internship, semester 1)
- + learned: sensors lie until you filter them
control systems
- + wall-e (self-balancing) and the maze solver — 4th place
- + joined SRA, started teaching what I had just learned
flying
- + e-Yantra warehouse drone, national semifinals
- + learned: camera-only localization is fragile (this comes back later)
the forklift
- + defence research internship at IIT Gandhinagar
- + wrote our own UWB ranging firmware: 45 m stock limit → 315 m
- + 0.4% error over 10,000 m², checked against a total station
the smart switch
- + hardware, firmware, cloud, app — all of it
- + started as a hobby, trying to make it a real product
Eyecandy Robotics
- + moved to Bangalore, designed the boards inside a small legged robot
- + compute carrier, motor driver, and a power board running 17 motors
- + learned: debugging other people's hardware teaches you more than debugging your own
the motor is the PCB
- + final year project: a coreless axial-flux motor etched into a circuit board
- + simulated it before fabbing and found a 3.3x torque loss in my own design
- - assuming anything about phase order
in progress
- ~ steel back plates on the motor, then re-measure Kv
- ~ open-sourcing the cat feeder
- ~ smart switch: perf board → real PCB, OTA updates
- ~ known issue: cannot stop building robots. won't fix.
