Robot Electromechanical Design Features 

Sensors

  • 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").
  • Measured last years optical sensor to have angle of operation of around +- 10 Degrees
  • Proposed optical beam-break for climber hooks - - - new IR-only sensor is Vishay TEST2600; new IR LED is Vishay TSAL6100
    • LED is 130mW/sr at center; 65mW/sr at +/- 10 degrees
    • 6" distance between emitter and detector = 15.24cm (r2=232.2cm2)
    • 130/232=0.56mW/cm2 yields about 1.5mA detector Ic; 65/232=0.28mW/cm2 yields about 0.8mA detector Ic; rated performance light intensity is 1mW/cm2, so we would be a bit below this but probably still usable.
  • Banner sensors
    • Q10RN6R is open-collector NPN (Dark Operate), so 10K pullup in Digital Sidecar is sufficient - no extra interface componets needed.

Robot Lights & Driver Circuits

  • Tricolor LED strip
    • 2A per 150 LEDs. 40mA per LED. Approx 750mA per 2 foot strip.
