Abstract: The localization of mobile robots is the precondition and key to the navigation control of mobile robots. Combining the technology of Cricket wireless localization with mobile robot control system, a robot control system based on the localization of wireless sensor networks was developed to complete the information transmission/incorporation between the Cricket localization system and mobile robot system and implement the localization and navigation control of the mobile object. The Cricket system exhibits high precision in localization with the error of sampling data fluctuating within 3 cm under static condition. The system time delay is around 60 ms when the mobile object changes its location at a relative rapid speed.
