LEGO fun



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,
