Bumper Step 0

Each bumper will hold a touch sensor. Attach the
electrical wires to RCX Input Ports 1 and 3. Make
sure that the program is written for the touch
sensors connecting to these ports. Remember to
build two bumpers!

Touch Bumpers

It is important to create a bumper in front of
the touch sensor instead of using the touch
sensor by itself. The bumper increases the sur-
face area of the touch sensor and allows for a
better response. It is also good to create the
bumper so that different amounts of pressure
will allow contact to the touch sensors.
Rubber bands or flexible tubing pieces are
also good choices when building bumpers.
The Constructopedia has several different
bumper ideas that could be substituted here.
