Implementation of Obstacle Avoidance and ZigBee Control Functions for Omni Directional Mobile Robot
Aim Of The Project To implement the obstacle avoidance and Zigbee control functions for Omni directional mobile robot.
Working Of Our Project In our project we are using IR sensor to sense the obstacle and send the obstacle distance signal to embedded controller. The embedded controller receives these obstacle detecting signals and then calculates the control signals to drive the motors to change the direction for the robot. ZigBee interface is also provided on the robot to give some control signals from the Personal computer attached with ZigBee enabled circuit. Using this ZigBee interface we can control the direction, speed for the robot.
What is Zigbee? Technological Standard Created for Control and Sensor Networks . Based on the IEEE 802.15.4 Standard. Created by the Zigbee Alliance Low data rate Low power consumption Small packet devices
What Does Zigbee Do? Designed for wireless controls and sensors. Operates in Personal Area Networks (PAN’s) and device-to-device networks Connectivity between small packet devices Control of lights, switches, thermostats, appliances, etc.
Implementing Method It consists of two sections Transmitter Section PC Zigbee Transmitter Receiving Section LPC2148 MICROCONTROLLER DC Motor Zigbee Receiver IR Transmitter and Receiver
