Robot 6 • The Aerial Tram

cabling wire by responding to electrical tape folded over in small flags on the
wire. Another way of using the light sensor for control is to program it to
respond to the beam from a flashlight when the beam is pointed directly at the
light sensor. This beam could be a bad-weather warning signal that tells the
tram to come back to the tower.
On each end of the tram, a bench is ready to seat your favorite LEGO fig-
ures for transport. The bottom of the tram allows for the cover of the RCX to
be removed easily for battery replacement. To enhance your LEGO Aerial Tram
further, you could make attachments to add to the bottom of the tram. A gon-
dola attachment could carry cargo in addition to passengers. A grabber arm
could be built and powered with the second motor for picking up or dropping
off items at certain locations or for completing tasks too hard to reach. Begin
with the basic design shown here, and let your imagination run wild as your
Aerial Tram flies over the canyon of your choice!
