Robot Electromechanical Design Features 

Frisbee Scorer (Shooter/Dumper)

  • Shooter
    • motor type: mini-CIM
    • variable speed motor drive: Jaguar
    • sensor for motor RPM: rotary encoder
  • Loader
    • rotary carousel motor type: snowblower
    • motor drive: variable speed or just maximum speed (relay)?
    • sensor for how many frisbees have been loaded
    • actuator for feeding frisbee to shooter: solenoid?
  • Dumper
  • Tilt
    • motor type: ?
    • variable speed motor drive: Jaguar
    • sensors?

Climbing Mechanism

  • Starting Position
    • sensor for robot V at pyramid corner: optical beam break (Banner?)
  • Deploy
    • Release stationary arms: solenoid or servo
  • Climb
    • Extend & retract climbing arms
      • motor type: 2x CIM
      • motor drive: variable speed Jaguar
      • arm position sensor: slotted optical sensor senses mechanical flag on shuttle - top, bottom, and home (middle). Redundant top and bottom?
    • sensors for climbing arms locked on: microswitches or optical (need to prototype)
      • microswitch with 2" lever arm measured to have 0.25" (1/4") travel at tip after switch engages before bottoming out (not much). Travel at tip from resting to engagement is about 0.1875" (3/16").

Drivetrain

  • 4 wheel or 6 wheel (?)
    • motor type: 2x CIM
    • variable speed motor controllers: 2x Jaguars
    • sensor for motor RPM: rotary encoders
  • Gyro

Robot Visual Indicators (pretty lights)

  • ready to feed frisbee - at feed slot - green for OK to feed, red for don't feed
  • how many frisbees loaded - visible from all sides
  • shooter up to speed and ready?
  • robot in position to climb - at top & sides of climber structure
  • climber deployed - at top & sides of climber structure
  • climber arms fully hooked on pyramid horizontal bar - at top of climber stucture
  • climber at full extension - at top & sides of climber structure
  • climber at full retract - at top & sides of climber structure
  • robot front direction indicator - arrows (?) on sides that point forward
