SURGE Mark.2: in-wheel direct-drive autonomous RC car with 10+ driving modes
4310sy · x · 2026-11-10
A Japanese maker published a full documentation site for SURGE Mark.2, an autonomous mini RC car built on Raspberry Pi 5 + STM32.
- Direct drive: rear wheels mount directly onto 5010/360KV drone BLDC rotors — no gears or belts — enabling per-wheel torque commands in N·m via a custom driver board running FOC at 20kHz.
- Safety-first stack: STM32 handles drive control at 2kHz and can stop the car even if the Pi 5 crashes or comms drop.
- 10+ autonomous modes: LiDAR mapping + localization with racing-line planning, mapless Follow-the-Gap, camera-based lane/boundary recognition, imitation learning, and sim-to-real reinforcement learning — each documented with source links.
