This is Tipsy my robot that I made from parts I had around my workshop. His main drive motors and wheels are an old cassette player. The solar panel is new. As you see in the video he can move and a bit too fast near the end.
It moves in any light, but the best movement is in direct sunlight.
Thanks ,I appreciate the quick response. I used the bare cassette deck, with the motor. Actually Tipsy, after a quick check was AOK. It took me a little longer to get over the scare of seeing him go down.
I take the word autonomous as that someone is not in direct control of the robot. I agree the level of sophistication is not that high in that it can only move in one direction. Having more control and more degrees of freedom would make it more autonomous. That is my hope for SAM.
