Electric Vehicle

Multiple vehicles capable of reaching an end point (with centimeter precision) in a timely manner.

Tyson:

Simple stepper motor design
Cornell run | MIT run | Brown run
Tyson_CAD

  • ESP32 MCU, TMC2209 Stepper Motor Driver
  • Carbon Fiber tube chassis

McQueen

Experimental build, first custom PCB & machined chassis.
McQueen_CAD

  • ESP32 MCU, H-bridge motor driver, BMI270 IMU, AMT102 Encoder, LDO.
  • Wi-fi Telemetry Interface.
  • S-Curve motion profiling that utilizes a precomputed table to reduce looptime.

Markova

Build for Nationals.
github repo
Nats run
McQueen_CAD

  • ESP32 MCU, BMI270 IMU, Switching PSU.
  • Lightweight 70 x 30 cm Aluminum Chassis.
  • First implementation of reverse voltage protection, ESD protection.
  • Off-board BLDC ESC.

I didn't find great photos of the real life builds, so CAD screenshots will have to do.
