Our second robot was DEWBOT II in 2006 and it played the game Aim High.DEWBOT II was a shooter primarily designed to score via the central high goal. Alternatively, it was able to drop its shooter elevation and score by shooting into the low goals as well. DEWBOT II reloaded by picking balls off the floor and lifting these into a gravity-fed hopper. The hopper then fed by gravity to the Shooter, located low and forwards. Shooter elevation could be changed for range or target. The shooter did not traverse. Side-to-side aiming was accomplished by aiming the robot. The overall lift, hopper, shooter system was generally reliable.
The robot possessed a 2wd drive-train which was simple, reliable, easy to steer and provided good agility.
Main strengths were:
- Very drivable
- Extremely reliable
- Flexible (could score on both high and low goals)
- Effective & efficient Ball pick-up
Primary weak points were:
- Low rate of fire
- Difficult aiming
- The low shooter was easy for opponants to block
- The robot was easily pushed out of shooting alignment
- DEWBOT II could not score bonus points

Design Details
The links below will take you to details about the robot components.
Drive Train
- A 2wd / rear wheel drive drive-train with unpowered omni wheels up front. Steering / driving was quite good, but the robot was easy to push around, especially from the front-side.
- It was almost impossible to climb the ramp at the match end to score bonus points. Center-of-mass was too high and far aft to allow DEWBOT II to climb the ramp forward (it would end up on its back). Drive wheels, however, would unweight and lose traction trying to run up backwards. It was possible to get up backwards with a good running start, but this was in large part a controlled crash.
Ball Handling, Shooter
- This is how we score. Dewbot II picks up Balls from the floor and loads them into a Hopper. From there, the Balls gravity feed to a Shooter to score in either the Center-High or Side-Low goals.
