Robot Electromechanical Design Features
Climbing Mechanism
- sensors for climbing arms locked on: optical beam break (mechanical lever switch is backup solution)
- 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 - - - 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.
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 - four stripes
- repurpose four stripes for climber status
- robot front direction indicator - arrows (?) on sides that point forward
