Touch Sensors

Home > Activities > Robots > Tutorials > Touch Sensors

Touch sensors let your robot sense contact. Use a bumper in front of the touch sensor so your robot can sense contact over a larger area.

Touch sensors connect to one of the three input ports numbered 1, 2, and 3 on the RCX. Your robot program can read the touch sensor and determine if the yellow button is pushed in or out. Then the program can take appropriate action, such as backing up and turning around.
