flyaruu/rc-car

Firmware for an RC car + controller, powered with 2 ESP32c3 controllers, all written in Rust.

Used for a series of youtube videos, starting here: https://www.youtube.com/watch?v=-kRTRKL39pE

Tech stack

• Rust
• Embassy (Async runtime for embedded devices)
• Postcard (serialization protocol)
• ESPNow (Low latency transport protocol)

It's a workspace project. 'Car' is the the controller of the car, 'controller' is the controller to steer the car, 'protocol' is shared code, mostly for the transfer message format.

Car hardware: Pretty much all 3d printed.

• Servo for steering
• BLDC drone motor + controller
• 2 cell LiPo battery
• Led head and tail lights
• 4 blinkers
• Reverse light
• Brake light

I created a separate dashboard project, to create a dashboard to add to the controller: https://github.com/flyaruu/rc-car-dashboard

Some silly features that are still on my to-do:

• Parking sensor
• Horn
• Collision sensor to trigger alarm light
• Upload telemetry.
