The object of this paper is to develop an autonomous hexapod bio-robot system. It uses 12 R/C servos for actuators. The degree of freedom of each leg is 2. The 6 R/C servos are for raising and lowering the legs, and the other 6 are for moving the legs forward and backward. This bio-robot can be used to study the walking theory of the robot. The processor is an Atmel 89C51. This hexapod robot has remote control function. User can use the radio wave remote controller to control the robot to move forward, backward, or make a left or right turn. This robot also has autonomous function. Two micro switches and two IR sensors can be used to detect obstacles. The robot can make a left or right turn to avoid the obstacle.
