Clean Sweep
The task: Build and program a sweeping machine to clear a large area quickly. The
vehicle should have two motors, each controlled by a touch sensor attached to a
cable.
The challenge: You will have thirty seconds to clear a large square containing
LEGO® bricks. You will earn a point for each brick you are able to push completely
out of the square in that time.
The catch: Your sweeper must be small enough to fit in a closet for storage. It can
be no longer or wider than 30 centimeters.
Good luck!
