UCSD's Coordinated Robotics Lab is working on their latest generation of the iFling, an R/C robot they call a "self-righting Segway-like vehicle." It picks up a ping pong ball, rolling over it and wedging it between body and wheel, then tosses. Its makers are hoping to get several to play catch and make them different sizes for larger balls. Look for the iFling in a toy store near you sometime in the future next to their other creations iHop and iceCube.
