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.
