Connecting A Bumper Switch - Hexbug VEX IQ User Manual

Connecting a Bumper Switch

Items you will need:
• Robot Brain with Radio and Robot Battery installed
• VEX IQ Controller with Radio and Controller Battery installed
• Smart Motor P/N: 228-2560
• Bumper Switch P/N: 228-2677
• Smart cable P/N: 228-2780
Bumper switches are input devices that give the Robot Brain a signal when they are pressed.
Bumper Switches can be used to turn off a motor when pressed.
All VEX IQ electronics are connected to the Robot Brain using Smart Cables. These cables
come in assorted lengths. All sensors should only be connected to the Robot Brain when the
power is OFF. Smart Cables can only be plugged in one way and they lock into place.
Connect the Bumper Switch to port 2 on the Robot Brain using the Smart Cable. Press each
side of the cable firmly into the socket on the Bumper Switch and Robot Brain until you hear
the click of the lock snapping into place. Connect a Smart Motor to the Robot Brain in port 4
using a Smart Cable.
• Turn On the Robot Brain and Controller.
• Select the Driver Control Program and run it.
• Press the top and bottom R buttons on the Controller. The Smart Motor should spin when
either button is pressed.
• Press the Bumper Switch and hold it down.
• Now try to press the R buttons again to move the motor. Notice how one of them no longer
works, because the Bumper Switch is sending the Robot Brain a signal to turn the motor
OFF in that direction only.
