ROBOT(black line)

The electric scheme is based on microcontroller ATmega128L. The source of power is eight batteries (type AA).
The photodiodes matrix (5x4) is located on the bottom of the case. The matrix is used for direction of the robot in movement along a black line. The bottom under the robot is lit up with infra-red light-emitting diodes.
Each conducted wheel of the robot is equipped with a gauge of turns.
There is an infra-red light-emitting diode and a photodiode on the front side of the robot. They are to identify an obstacle in front of the robot. The gauge can identify an obstacle in distance up 0,6 meters.
The identifications of light exposure in front of the robot is carried out by three photo-resistor. They are connected to analog inputs of microcontroller.
