Compact Zig bee Hand Held Unit For Robot Control project is developed by using Zig Bee protocol . This protocol is a free open source protocol which can be downloaded and used for developing this type of applications. This protocol is a low cost protocol with low power wireless sensor network. This protocol will provide reliable delivery of data between remote sensors. This application works at ISM 2.4 GHZ frequency.

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.
