It has been designed and fabricated robot obstacle avoidance using ultrasonic Sensors based microcontroller AT89S51. Ultrasonic sensors to function as an input that will beprocessed by the microcontroller AT89S51 to turn on or turn off the motor.Obstacleavoidance robot consists  of three pairs of ultrasonic sensors, where a pair of ultrasonic sensors consist of a series of sensor transmitter and receiver sensor circuit, a DC motor drive  circuit  and the minimum system using IC AT89S51. Transmitter and receiver sensors ultrasonic sensors placed side by side, at a distance of 10 cm or less than 10 cm where tension is 900 mV or more than 900 mV robot  will  turn.
