Is there a way to program a robot with python (ex, an electric motor, control it's speed, etc)

The answers to your questions depend very much on what you're working
with and how the motor is controlled. Is this supposed to be a
self-contained machine, or is it supposed to be connected to a personal
computer as a peripheral device?

The easier way is the peripheral device. In that case, you need some way
of sending signals e.g. from your computer's parallel or serial port to
a relay switch or voltage controller that controls your motor. In that
case, apart from the nitty gritty hardware to make the physical
connections, it's a matter of controlling the parallel or serial port
that the "robot" is attached to, which can definitely be done in Python.

I won't go into details because you're not saying enough about your
project constraints, and as fascinating as your question is, it is
somewhat off-topic on this list (as if that's a deterrent to discussing
something on this list ;-). As John said, you're more likely to receive
useful advice on comp.robotics.misc.

Good luck,
