In the final year, with the development of industry and technology it became necessary to design the robots specially
within dangerous regions that are difficult for human to reach. The autonomous clever robots are robots which can perform required tasks in unstructured ambiences without ceaseless human steering. In this paper an intelligent
mobile robot was designed to avoid obstacles depending on threshold method that is used a three ultrasonic sensors: the first is located on the right, the second is on the front and the third is on the left and the microcontroller (Arduino UNO). The robot gets the information from surrounding area through mounted sensors on the robot, through frequency signals that were continuously emitted by the ultrasonic sensors. These signals are reflected back when the obstacle is detected which then considered as input to the sensors through echo pin. The objective of this research is to design and implement the intelligent mobile robot which can be performed required tasks in unstructured ambiances without incessant human guidance.

Keywords: Microcontroller, three ultrasonic sensors, mobile robot.
