Historically, acquiring and effectively manipulating gamepieces has been 816's biggest weakness. This year with some help from Chris Picone and one of our new Sponsors "The Inventor's Shop" we've built a halfway decent claw.

The Orange Belting is 1/8" Polycord, and the black rubber material is similar to the wrap found on tennis rackets. Some of the struggling you see in the video was because of the awkward holding angle of the Drill Roller Claw combo. For the competition version we're planning on running a RS540/550 series motor through a Banebots 36mm planetary.
(P.S. the reason the camera guy tells someone they're not allowed to be in the video is because 816's High School does not allow students to be in any youtube videos. I believe the penalty for breaking this rule is relatively severe.)
