Grabber Arm
Use the second motor to power a grabbing arm. Attach the arm to the
base of the tram. The arm can carry things across the canyon, pick things
up, or drop items where needed. Program the light sensor to open and
close the grabber arm in response to a flashlight signal.

The Touch Bumper

The bumpers on each end of the tram allow the tram to sense when it is at the end of the cable
line, so it can stop or pause and reverse directions. You will need to build one bumper for the front
of the tram and another one for the back.
