Implementation of obstacle avoidance and zig bee control functions for omni directional mobile robot

  1. 1. IMPLEMENTATION OF OBSTACLE AVOIDANCE ANDZIGBEE CONTROL FUNCTIONS FOR OMNIDIRECTIONAL MOBILE ROBOT(ABSTRACT)Mobile robots perform various ways of tasks toserve humans such as home robot, inspection robot, securityrobot, school education robot, rehabilitation robot, and so on.The conventional mobile robots have used front-steering andrear- wheel driving mechanism to response all needed robotobvious motions, but the motion restriction is a majorproblem in the use of such mechanism. The omni directionalconfiguration is a most suggested mechanism for mobilerobot, which to have the capability of changing directionswithin the limited space in the indoor environment.The ODMR (Omni directional mobile robot) uses IRsensor to sense the obstacle and send the obstacle distancesignal to embedded controller. The embedded controllerreceives these obstacle detecting signals and then calculatesthe control signals to drive the motors to change the directionfor the robot. ZigBee interface is also provided on the robot togive some control signals from the Personal computerwww.nanocdac.com www.nsrcnano.com branches: hyderabad nagpur
  2. 2. attached with ZigBee enabled circuit. Using this ZigBeeinterface we can control the direction, speed for the robot.In our proposed robot we are using microcontroller tocontrol the IR sensor and robot Motors. Robot can move inany direction. But when any obstacle comes in front of therobot, IR sensor senses that obstacle and send appropriatesignal to the microcontroller. Once the microcontrollerreceives IR signal then it itself having program to givenecessary control instructions to motor or it will send that IRdetection signals to personal computer using wireless link ofZigbee. PC having programmed that will provide appropriatecontrol signals to microcontroller using Zigbee wireless link.After receiving this signal at microcontroller, it direct thatsignal to the motor.In this project we going use microcontroller, which thecurrent dominant microcontroller in mobile based productsand software development Tool as Keil, flash magic forloading hex file in to the microcontrollerSOFTWARE: Embedded ‘C’TOOLS: Keil, Flash magic.www.nanocdac.com www.nsrcnano.com branches: hyderabad nagpur
