PC CONTROLLED ROBOT USING ZIGBEE WIRELESS
COMMUNICATION
ABSTRACT:
The Xbee/Xbee-PRO RF Modules are designed to operate within the ZigBee protocol and
support the unique needs of low-cost, low-power wireless sensor networks. The modules require
minimal power and provide reliable delivery of data between remote devices. The modules operate
within the ISM 2.4 GHz frequency band
Zigbee is a worldwide open standard for wireless radio networks in the monitoring and
control fields. The standard was developed by the ZigBee Alliance (an association of international
companies) to meet the following principal needs
low cost
ultra-low power consumption
use of unlicensed radio bands
cheap and easy installation
flexible and extendable networks
integrated intelligence for network set-up and message routing
To control the direction of the robot we are using Xbee modules one as transmitter and the
other as receiver. The transmitter is fixed to PC and the receiver is fixed to the robot on the other
end. We send signals from PC through the Xbee (transmitter) to the receiver which is in built to the
robot.

We can use this process to visually control the robot direction even though we are far away
by connecting a camera in front of the robot.
