The Pololu IR beacons are small infrared transceivers meant to be used in pairs to give autonomous robots simple means for detecting each other. You can use the beacons to build pairs of robots that interact or chase one another, or to make a robot that can identify and return to a home base. For example, you could build a “cat robot” and “mouse robot” that each have an IR beacon, where the cat chases the mouse and the mouse runs away from the cat.

These newer IR beacons feature round PCBs with six wide-angle emitters to provide uniform broadcasting in all directions. The operating voltage range has increased to 6 – 16 V, and on-board voltage monitoring enables a more consistent output brightness over the voltage range. Most components are pre-assembled, so all you need to solder is the connectors and sensors (make sure you solder them in from the bottom of the PCB!).
