In the design and manufacture of robots robot forms and concepts influenced by the function and purpose of the robot. Six-legged robot (hexapod) is the most widely used because hexapod has many advantages, among them is the flexibility in movement pattern, since it is more stable robot because the robot is at least three or more feet on the ground when moving. In this study, researchers discuss robotic navigation system by utilizing the expert system which uses Forward chaining inference method, and then use as a robot brain Raspberry and microcontroller Atmega 32 as drive control robot legs. Later in this study researchers used an ultrasonic distance sensor as the sense of sight robot. Results of this research is a hexapod robot which navigate by using the rule of an expert to be able to navigate a location that has been determined by the expert.
