Navigation control device of mobile robot

The invention relates to a navigation control device of a mobile robot, which is based on the distributed structure of a CAN (Controller Area Network) bus, and comprises an ARM9 (Advanced Reduced instruction-set computer Machine9) processing unit, an ARM7 processing unit and a DSP (Digital Signal Processor) processing unit, wherein the ARM9 processing unit is used for carrying out the communication connection with the ARM7 processing unit and the DSP processing unit via the CAN bus, so as to complete the information fusion and navigation planning of various sensors; the ARM7 processing unit is used for acquiring the information of the sensors and sending the information thereof to the ARM9 processing unit; and the DSP processing unit is used for receiving the motion control instruction of the ARM9 processing unit, so as to achieve the servo control of the motion executing mechanism of the robot. By achieving the distributed connection of the embedded micro-processor via the CAN bus, the device of the invention can effectively reduce the computational burden of each processing unit and guarantee the real-time performance of the system; by arranging a plurality of interfaces, the invention improves the flexibility in expanding and updating the navigation control device; and by using the embedded micro-processors, the invention has the advantages of low consumption, thereby meeting the requirements for the running time of the robot in families and public environment.
