The SparkFun RedBot Mechanical Bumper is a collision-detection sensor that uses a spring-steel "whisker" to detect obstacles before your robot makes contact. When the whisker bumps into an object, it closes a simple SPST switch connection, triggering a response such as stopping the motors.

The sensor connects to the RedBot Mainboard via a 3-pin header using female-to-female jumper wires. Use the included RedBot library for easy integration into your collision-avoidance code.
