Meet AIMe: a compact robot that pans and tilts your camera to keep you in the frame. It uses EmIT, an emitter, to track moving objects. You can use the device with smartphones and small cameras under 10 ounces. AIMe pro has even a larger load capacity, capable of handling cameras up to 15 lbs.
To get started, attach an EmIT to a moving object and let the robot do the tracking. AIMe moves up to 100 times per second for responsive tracking.
