The build began as a simple two-motor, skid-steer RC car build with a fan for suction. Controlled by a smartphone app, a cheap Arduino board with an HC-05 Bluetooth module ran the show.

With the code written, [Indeterminate Design] turned to the 3D printer to build the prototype controller ... involves sensing the forces in the RC car which will then get sent back to the remote.

Designed for dirt trails, rock-crawling challenges, or racing on asphalt, modern RC cars combine advanced engineering and performance to handle various terrains. These vehicles replicate the ...
