The groups made a vehicle from the H instructions in the Simple Motorized
Machine sets
and modified them to be able to carry food for the zoo animals.
The Zoo was set up with a place for each kind of animal.
Robolab was used to program the RCX to make the vehicles go forward,
stop, and back.
One member of each group kept the wires from tangling and the other
took the food off to give to the animal.
