This robot controlled by a visual basic program, and can move in three different speeds by a pulse
width modulated (PWM) signal generated by a PIC microcontroller. This robot can carry objects sized
from 3 - 18 cm from place to another within 150 m.
The robot can be operated in two modes, normal control and light tracker mode.
Many sensors are used, such as light sensors; tilt sensor, stall current sensing, battery level
sensing, and some limit switches and touch sensors used in the hand.

It can keep its speed constant when it goes on a hill (tilted)
And turn on the light when it's in dark.
Its follows the light when operated in light tracker mode.
Also to keep the IC's in safe it disconnects the current when it's stuck. And the hand stopped while
holding something.

4 DC motors was used controlled by a PIC microcontroller 16F877
and 3 motor driver.

it takes about 4 monthes,and costs about 600$
