Who was it that built the 'sewer rat' ( a robot that fitted in a pipe, with
4 sets of wheels contacting the walls of the pipe)? It shouldn't be
insanely hard to modify into a 'sphere rat'! Did the original sewer rat use
synchro drives or fixed axles?
Now who's going to build the required gyroscope RCX sensor :)? You'll need
one because when you brake the wheels, the sphere will keep rolling, meaning
the robot will be turning as well. Call me a masochist, but it sounds like
a fun project.
Ben.
