The CYBUG KIT is designed to behave and appear insect-like, and has full obstacle avoidance and reversing motors. The robo-organism is nocturnal ( most active at night ) and can be configured to be photo-tropic ( light seeking ) or photo-phobic ( light avoiding ). A quick adjustment of the potentiometer causes the CYBUG to behave aggressively as a predator, or timid and slow moving like a herbivore. No two CYBUG are exactly the same and you will come to recognize the unique characteristics of each! The CYBUG's behavior can be enhances by adding on the Higher Brain Function daughter-boards: The HUNGER ( HBF-1 ) and PREDATOR (HBF-2). Instruction manual discusses operation of CYBUG and all components used at a novice level. ( Kit requires soldering iron and basic handtools. 3 hours estimated completion time.)
