A flying robot that tracks *you.* But it doesn’t follow you, it leads you, the idea being that it helps you set a pace while you’re out jogging. The robot tracks you visually by keeping an eye on a specially patterned t-shirt. One is left to wonder what it does when it loses track of that special target… does it hover? Orbit around? Commit suicide?

Seems to me, a more entertaining concept would be to make it into a game of robotic “tag.”
