2012:Shooter and Collector

Shooter Design

• 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?

Resources

• Ball Trajectory Calculation spreadsheet
• Math behind the above spreadsheet
• Foil Sim III - Air flow simulator; useful for approximating drag effects on a ball
