A novel intelligently tracking car is presented in this paper, based on IEEE Standard 802154, Zigbee wireless module and ultrasonic sensors. The system is designed based on the PIC18F4620 micro-controller and MRF24J40MA RF Transceiver Module. The system uses RF Communication for the identification and synchronization of nodes, and ultrasonic module for distance measurement and positioning, thus controlling the motors in the car to track the specific target at a certain distance. The control network is composed of sub-nets to control different systems using time-division strategy. Meanwhile, the network is responsible for managing accessing of new systems and switching between sub-nets. Test results prove that the designed system is reasonable for intelligently tracking, and is useful in practical engineering.
