Easy and fun to assemble. The detection block can be replaced if desired without changing the basic design of the device.
- intelligence relies on the PIC16F630 (DIP14) microcontroller
- programming connector on the top card
- pre-programmed circuit code protected
- red LEDs indicating operation
- obstacle detection is done by three infrared batteries placed on a separate card
- common IR power control
- separate sensitivity adjustment for each pair
- provides a designated signal at the "voltage level" of the obstacles it detects
- two DC motors with gearing and large wheels
- 68 mm wheels with rubber coating
- mounts directly on the bevel gear at the rear of the motor
- runs on 4x AA batteries (battery holders under the base plate)
