Small 3-wheel ROBOT with PIC16F84 brain & InfraRed eyes, By: TJACO. Page: 1-2-3-4-Home

The circuit is built on another piece of circuit board which is identical to the base plate. The circuit is placed on top of the base plate. The 3.6 Volt battery pack (from a cordless phone) is also glued to the base plate.

Circuit description

The circuit behind CERBERES can be divided in 3 parts:

A double motor drive to drive two small electric motors forward / reverse / full stop. Two infrared emitters and receivers to sense objects. A "brain" which is a PIC 16F84 µController which will drive the motors in reaction to the sensor readings.
