A repulsorcam was an audio/video recorder that was mounted on a tiny repulsorlift. It was mounted on a droid's chassis, and could be deployed to fly to a remote location and record. It had enough internal memory to store 2 hours of audio and video.
A single energy cell provided enough power for 4 hours. The repulsorcam could be recharged by docking with the droid or on a separate external charging station.
