Here's a video of 1583's chassis and mechanism prototypes.

The chassis prototype is a 27 inch octagon with CIMs powering Banebot gearboxes coupled to AndyMark 6 inch omnis. The mechanism prototype consists of a ball possesion device (we call it a dribbler) and a shooter. We've spent the last week improving and enhancing both prototypes. For example the competition chassis will have P80 Banebot gearboxes and dual AndyMark wheels on each axle. The competition mechanism will have a more powerful shooter. The prototype uses the window motor motor/gearbox. The competition mechanism will have a CIM/toughbox with a anti-backdrive device. The window motor setup shoots the ball about 8 feet. The new more powerful shooter will shoot it full court. Btw, we learned that back driving the ball with our dribbler doesn't make the ball roll very good on the ground. Hence the shooter is designed to loft the ball into the goal. We'll show more of details of the robot as we start building the competition model next week. In 2008 team 1625 Winnovation was in the pit next to ours at the Colorado regional. Their cocking and trigger concept from their 2008 robot is what we are using this year. Thanks guys.
