Pomelo Pummeler

2017

Our 2017 STEAMWORKS competition robot, “Pomelo Pummeler” was able to shoot fuel to the high boiler goal, collect and retrieve gears for the “airship,” and use its climber to reach the top of the rope on the airship in the last 30 seconds of a match.

scoring

Our 2017 robot was equipped with a shooter and a ground intake mechanism. The ground fuel intake could collect about 60 fuel pieces from the game field, and funnel them into the magazine for storage. Using a belt and roller system, the fuel then fed from the magazine into the shooter mechanism. The shooter had two different flywheels that allow two streams of balls to be fired at once, giving the robot the ability to achieve up to 40 kPA in autonomous mode. On the back of the robot, there was a gear intake designed to intake a gear from the ground. A pop-up roller combined with AndyMark compliant wheels trapped the gear to be scored on the airship lift.

Drivetrain

The West Coast Drive used on the Pomelo Pummeler had two omni wheels in the front, and four colson wheels to provide traction in the middle and back. There were four CIM motors allowing the robot to hit a top speed of 17.5 feet per second.

Electrical

A wheel and vertical joystick made driving the Pomelo Pummeler easy by controlling the angle and speed of the robot respectively. The wheel allowed for tight turns to be executed, maneuvering the robot smoothly around defense, while the throttle joystick enabled the driver to easily score gears and shoot fuel. An Xbox 360 game controller was used to control the other mechanisms on the robot, including the ball and gear intakes, the magazine conveyors, and the climber. A small screen was also used by the drive team to view video streamed from a camera mounted above the ground gear mechanism. The feed showed gears that cannot be seen by the drive team, and makes gear acquisition and scoring much easier.
