 Robot Abilities


First Iteration: Regionals

  • Frisbee Shooter - 1 Banebot RS-550 motor is connected to a Vex 3:1 Planetary Gearbox, which powers an Andymark Pneumatic wheel. Frisbees are pushed into the wheel by 2 Bimba pneumatic pistons. The angle and speed of the shooter is fixed, and it is angled to shoot at the top goal from the corner of the pyramid.
  • Hopper - The hopper can store a total of 4 Frisbees. 2 Frisbees are stored in the shooter, and 2 more are stacked in the top of the hopper. Once the 2 Frisbees stored in the shooter are fired, a pneumatic piston retracts, and allows 2 more Frisbees to fall into the shooter
  • Climber - Our climber can climb the 1st level. 2 Large Pneumatic pistons are attached to bars on the side of the robot. 2 large and slightly modified meat hooks are attached to the pistons, and pull up the robot at the end of the game.

Second Iteration: CalGames

  • Frisbee Shooter - 2 BaneBot RS-550 motors. The one closer to the loaded Frisbees is on a 3:1 reduction, and the one farther is a 1:1 direct drive, both motors connected to soft blue BaneBots wheels. Frisbees are pushed in with a long piston.
  • Hopper - similar to before, but all 4 Frisbees are in the shooter, ready to be fired out one by one.
  • All other features the same

 Game Summary


For a more detailed explanation, see the Wikipedia article and the game animation.

     This year’s game was based off of Ultimate Frisbee. There are 5 goals at which we try to shoot Frisbees. The bottom goal is worth 1 point, the mid height goals are worth 2 points, and the top goal is worth 3 points. As you go higher, the goals get smaller as well. The most valuable goal is located at the top of each pyramid and is worth 5 points, but people rarely shoot for those. At the start of each match, there is a 15 second autonomous period, where robots operate only based off of their programmed code, without any operator input. There is a 2x multiplier applied to any goal scored during the autonomous period. During this period of time, our robot fires 3 Frisbees, and usually makes 2 of those. After autonomous ends, humans can start operating the robots. For 2 minutes we try to score as many points as we can by driving around the field, picking up Frisbees at the feeder stations and shooting at the goals.

     It is also possible to score points by climbing the 2 pyramids in the middle of the field. It is possible to climb at any point during the tele-operated period of the match. There are 3 tiers of climbing. The 1st level is worth 10 points, the 2nd is worth 20, and the 3rd is worth 30. We, along with most other teams, climbed the first level at the end of the match, after we have scored as many Frisbees as we can.

 Fun Facts/Stories


Our robot originally had a large climbing mechanism, but we took it off on the Sunday before Bag and Tag

The old hopper only worked because the vibrations from the shooter shook the Frisbees into place. Part of the reason why it was replaced.

The pistons used for our 10 point climber are called "Alejandro" and "Will".

The robot had extremely low clearance above the ground. Debris from outreach events and possibly on the field that ventured into the gearboxes required them to be completely rebuilt for CalGames, though they were the same overall.
