Communication of Multi Mobile-Robots Based On ZigBee Network

Taskeen Sultana, Zeenath

Robots can replace human working in some high-risk environment and scientific research Activities. With the rapid development of economic and technology, more and more service robots are widely used in a lot of machineries. How to effectively and reliably control the robots to serve human has become the focus of the study. The introduction of service robot wireless control system greatly improved travel efficiency and convenience for the disabled. It plays an important role not only to the operator but also to the caregiver. A novel wireless control system is designed in the paper. It can control the robot and feedback information in real time with ultrasonic obstacle avoidance function. The wireless monitoring hardware system for service robot is composed of upper PC workstation, MCU module, wireless communication module, ultrasonic sensor, wireless image transmission module, service robots and other parts. ultrasonic obstacle avoidance circuit used to obtain obstacles information sufficiently program to measure the distance between service robot and obstacles around.The wireless CMOS camera is chosen for the real-time image transmission Image contains a wealth of environmental information around the robot, which is equivalent to the function of its eyes. The wireless receiver (EM250 Single-Chip ZigBee which is of 2.4GHz, IEEE 802.15.4-compliant transceiver).) is connected to the upper computer. The caregiver can monitor and control the robot in real time. It can also recognize and determine the initial target pose of robot.PC is the master of the system. Its role is to determine the next step of the motion and send commands based on the environmental information around the service robot. For solving the problem of the cooperation between multi-robots, a communication system based on the ZigBee network was designed. In the hardware of the robots, the ZigBee nodes are introduced. The multi-robots form a star network by the ZigBee nodes, and they keep communication with each other by the central node. The ZigBee network has many characteristics such as low cost, low power-consume, strong anti-jamming ability and real-time performance etc, it adapts to the application of intelligence. Experiments showed that the communication between the robots is reliable. This scheme is a good way for robots to complete complex task and improve working efficiency.
