A simple robot 
A suitable vehicle needs the following:
- a left motor (LM)
- a right motor (RM)
- a left sensor (LS)
- a right sensor (LR)

A suitable program needs the following:
- a way of driving each motor as a function of 
the reading on the sensor on the opposite side

And the environment needs to ensure that the 
change in sensory inputs produced by the 
movement of the vehicle leads to some interesting 
and obviously useful behaviour…
…with a simple performance measure so that 
we can have a competition
