Can anyone here help me with a problem I have with a 1980's bump n go
robot,
the bump n go is purely mechanical and I don't have a very good mechanical
mind so I am not quite sure how this works, I have spent an hour searching
the net but have had no luck finding any info on how this mechanism works
or
what to do if it has a problem. Anyhow the problem is that the robot
mostly
spins on the spot, I presume it is suppose to go straight until it hits an
obstacle. I can see how everything else works but can't figure out how it
achieves the bump n go. So if someone could either point me in the right
direction or help me out directly it would be much appreciated. I would
really like to find a webpage that describes how this works.


To clarify, I am talking about a very simple toy robot, not really a robot
at all but a toy that looks like a robot, there are no fancy electronics,
just a dc motor, lights and wires, everything else is done by mechanics.
Here is a link that shows the toy I am talking about
