Meet AIMe Pro: a little robot that attaches to your camera and tilts/pans it automatically to keep moving objects in the frame. It can handle cameras up to 15 lbs. AIMe tracks an emitter called EmIT. To get started, put an EmIT on a subject, and the rest is easy. AIMe moves up to 100 times per second for responsive, smooth tracking.
AIMe is compatible with many cameras and smartphones. It comes with quick release top & bottom mounts. You can find out more here.
