Snarebot¶

Design¶

• Mechanical
• Double Arm Structure
  • Forearm (solenoid actuated) and wrist (servo actuated)
  • Forearm retract cannot contact drum (adds velocity only)
  • Drum hit is accomplished by servo positioning
    • Must ensure that solenoid duty cycle (10%, max 60sec per activation) is not exceeded
  • Heavy base with mounted circuits
  • brass tubing creates raised structure, held together by stay cables
  • Large solenoids mounted on base, connected to thin rods
  • drumsticks held dynamically in pvc foam holder
  • pvc foam holders pivot on brass structure, connected to the thin rods

• Electrical
  • 2 signal pins in, 5V in, 12V in, Ground in.
  • 2 outputs, which are 12V corresponding to the signal pins.
