This document proposes a wireless intelligent control system for service robots. The system uses Zigbee modules for wireless communication between a PC workstation and a service robot. The robot is equipped with an ultrasonic distance sensor for obstacle avoidance, an ARM LPC 2148 controller, a wireless camera for image transmission, and an L293D motor driver. The system is designed to allow real-time feedback control of the robot over Zigbee networks for applications like home automation and sensor networks. Hardware requirements include the controller, Zigbee modules, sensors, and software like KEIL is needed for development. The goal is effective and reliable wireless robotic control with ultrasonic obstacle detection.
