  • Turret-mounted
    • Approx. 280 degrees of rotation minimum need final range
    • 1-degree precision
    • Mechanical hardstops
    • Absolute angular position sensor
    • Need motor and power controller
  • 2-Wheel shooter
    • Must be able to impart backspin
    • Fixed angle of shot -- approximately 60-70 degrees above floor
    • Each wheel independently controlled (to control backspin)
    • Powered by Fisher-Price motor on speed controllers
    • Sensor for RPM on each
      • Provide sufficient resolution for rapid speed control update
      • Identify sensor characteristics
  • Camera mounted on turret
    • Must have direct light source inline with lens
    • Do we need pan? tilt?

Beater Bar Design

  • Fixed position within frame, as close to perimeter as possible
  • 1 speed forward, 1 speed reverse (full speed? can use relay?)
  • Pushes balls in and on to first conveyor section
  • Identify motor

Wings/V-collector Design

  • V-shaped collector outside of robot
  • Articulated up/in and down/out -- 2-position motion
  • Just a plain bars, no actual motion on the bars themselves
