Task 3: Doctors need a machine to move all of their operating equipment and generators, at one time, from room to room.

Must create a cardio regulator.

The equipment is very heavy. The machine can move slowly, but it must be capable of carrying a lot of weight.

Must have only one input to run all devices in order to save energy.

Must be no larger than 10 in. x 10 in.
