I think the model level car is getting close to understandable. Not so the toy. This video shows one under control, not the other.



One more step for the model level - get it more up to speed. This needs a bigger room. I've got that, but it needs cleaning. The toy level needs my understanding of the servo that drives the steering. Presently the car does not easily go straight hugging the wall. It just goes left or right. I will clean up and post my code.
