FRC 1539 2009 Robot - Completed and Testing

A documentary of our robot on its first day completed, including lovely shots of the robot in action as well as some team member cameos. The robot is under operator control for this entire video. The robot, in brief, uses a basic tank-style four-wheel-drive system, with one CIM motor driving each side of the drivetrain through standard AndyMark ToughBox transmissions. The frame is welded one-inch square hollow aluminum tubing. The upright plates are waterjet-cut quarter-inch aluminum, and are cut out to read "Clover" on one side, and "Eagles" on the other side. The uprights contain a top and bottom roller than respectively "shoot out" and "suck in" balls off of the floor. These rollers are PVC pipe, drilled in a rotating pattern and laced through with one piece of Polycord to act as "paddles" of sorts. The rollers are both powered off of one CIM run through a BaneBots 4:1 planetary transmission. The drive motor for the rollers is oddly placed, being bolted into the top of the upright plates. This is a result of some last-minute design revisions. The balls are pushed up by a plate attached to a belt-driven linear actuator run by a Fisher-Price motor running through a BaneBots 64:1 planetary transmission. We have been able to score a comfortable maximum of five balls at one time from picking up the balls off of the floor. We are also able to score a complete seven-ball preload, but are not able to pick up more than five balls off of the floor due to the weight of the balls and the excess force placed on our rollers.
We are attending the VCU Regional this year, hope to see you there!
Phone video, so not the best quality.
