DEWBOT II's scoring system is designed to:

1. Score by shooting balls into the central high goal
2. Alternatively score by schooting balls into the low side goals
3. Collect balls off the playing field to reload the Shooter's storage hopper

Overview

Beater Bar

A high-speed (ungeared Mabuchi RS-545SH2485 on a speed controller) front Beater Bar caught balls and drove them back to the Ball Lift. The Beater Bar also prevented balls from being lost during robot reverse drive. A pair of guides directed the balls into the Ball Lift entrance.

Ball Lift

The Ball Lift is a vertical conveyor tower having a pair of conveyors: Left and Right.

Each conveyot comprises:

• (5) 3/8" OD latex tube "cords"
• (7) conveyor rollers
• A Globe Motor direct drive of the bottom-most roller
• A spring tensioner on the top-most roller
