Abstract
In recent years,robots have been used in various scenes .It is useful to work in hazardous locations where human can not be activities. There are many cases interrupted communication in the accident. So the robot which can do autonomous movement is required. It is necessary that creating an environment map and selecting an optimum route. In this study,we try an autonomous mobile robot to recognize the position and posture of its body by using a depth sensor and rotary encoder ,and use Dijkstra's algorithm to have the shortest path plan to the goal of the robot.
