Robot Features

  • Drive Train
    • 6 wheel blue-nitrile West Coast drivetrain
    • High Gear 16 ft/s
    • Low Gear 3 ft/s
    • 8″x1″ IFI Traction Wheels 4wd Wide Base w/ Blue Nitrile
  • Shooter
    • Frisbee is gripped tight by wedgetop tread on IFI shooter wheel and compression of pool noodle foam on outer curve of shooter channel
    • Powered by two medium CIM motors
    • Output angle of shooter is lined up to 3 point goal when robot is flush to the feeder station
    • Frisbee runs along tracks to allow free flow of air under the frisbee
    • Visual Tracking Assistant (Not Override)
    • Hall effect sensor measures the period between flywheel revolutions
    • Vertical angle of shooter is adjusted by a lead screw powered by a window motor
    • Grayhill motor encoder allows for precise adjustment and presets
    • 3 presets for feeder station, mid-field, and pyramid
    • Manual control for slight adjustments
    • Adjusted by a custom two-speed bang-bang controller which allows us to reach presets with minimum oscillation.
  • Lifting Mechanism
    • Lifting mechanism powered by two pneumatic pistons
    • Two “isolated” air tanks dedicated to lifting ensure we can always lift even if we are out of air for shooting and shifting
    • Limit switch triggers to allow for automatic lifting
    • Driver simply holds a button and the robot will lift when the limit switch is triggered


  • Finding the correct angle for launching the frisbees
  • A high center of gravity caused the robot to be very tipsy, this cost us a few matches due to high speed driving.
