Juggling Robot


(Video Link)


Once you've developed robots that can feed on human flesh, the next obvious step is to teach it to juggle. This amazing robot can juggle a ping-pong ball and, very briefly, two. Moreover, it accomplishes this feat without any external sensors. The robot can't see or hear the ball. Rather, it calculates where the ball will land:

How does the robot do this? The key elements are the shape of the paddle and how the robot strikes the ball. We used mathematical analysis to learn which shape and motion would make "sensorless" juggling possible. What we found was that a slightly concave paddle keeps the ball on the plate and that a decelerating motion keeps the ball in the air.

The robot uses cameras to view the ball. At the 30 sec mark you can see that the robot has a visual tracking system, as it is tracking the ball before it is dropped on the paddle. If you view the additional video that is on the channel for the user, you will see the breakdown of how the robot tracks the ball. It would be cool if it was doing this on estimation though, but it, sadly, is not.
