1. Implementation of Obstacle Avoidance and ZigBee Control Functions for Omni Directional Mobile Robot

2. Aim Of The Project
To implement the obstacle avoidance and Zigbee control functions for Omni directional mobile robot.

3. 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.

4. What is Zigbee?
Technological Standard Created for Control and Sensor Networks .
Based on the IEEE Standard.
Created by the Zigbee Alliance
Low data rate
Low power consumption
Small packet devices

5. 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.
