Autonomous Mobile Robot Based on Differential Global Positioning System

The autonomous mobile robots have self perception, decision making and execution function with larger working space compare with the traditional industrial robots, which are widely used for the situation of medical monitoring, military reconnaissance, substation inspection and etc. It has the advantages of saving human resources, avoiding dangerous situations and more efficient. In order to implement Autonomous Mobile, a centimeter-level high-precision system are designed based on Differential GPS. A new algorithm are mainly introduced which is to confirm the position of the mobile robot with single high precision GPS and without compass.
