When up on blocks and I am fooling the sonar with my hands. (Remember it is supposed to hug the walls and thereby go around a room counter clockwise looking down.)

It:
1. goes straight when my hand is about 10 inches away on the car's right side and nothing is in front.
2. turns right when my hand is more than 10 inches away on the right
3. turns left when my hand is 15 to 20 inches away up front
4. goes backward when my hand is much closer up front. Once it has retreated 15 to 20 inches it turns left and tries again.

When on the floor the car is too fast for the PIC driven steering mechanism. It bumps into things, retreats, turns, and comes flying forward. It is too fast for me.

It is behaving similarly to those floor vacuuming robots only way too fast. I have the electronic speed control at its slowest PWM settings.

Needless to say, manipulating a video camera while waving my hand at this machine ain't easy.
