Comments:
- 1-1 differential drive
- 2 touch sensors used to count every half revolution for accurate movement and collision detection
- motors driven via PWM to avoid damage during collisions since we are not using the clutch gear
- tray and RCX2 is on a hinge, somewhat like a hatch back, for easy access to battry compartment
- funny looking antenna thing is used to indicate the tray has been loaded. Light sensor repurposed as a touch sensor
Cheers,
