It lets a microprocessor know if some critical voltage level is present. Like for some external device. Google the part number. They come preset for anything from 800 mv to 6 volts.

These devices are normally used to reset a microcontroller if the voltage falls below a certain point, mostly these are used as "brown out" detectors, they usually hold the output at that level until the voltage goes back up to a suitable range for the uc to function...

The ones used in Beam bots are actually voltage triggers, they operate in the exact opposite as the supervisory IC, the ones used in Beambots are ones that trigger when a voltage reaches a certain point (solarbots use these types to monitor capacitor charge level, when it reaches a certain voltage, it will either set an output low or high depending on device to trigger a motor or coil.)
