OVERVIEW OF THE XBEE CONTROLLED VEHICHLE
This project illustrates the control of a robotic vehichle with a Joystick via X Bee wireless communication. One Mbed is available on the Robot and the other Mbed is mounted on the Controller for the Robot. An SD Card, a Speaker and an Audio Amplifier will be used to give out audible sounds as the robot translates. An IMU will also be available as an alternative means of steering the robot. A H bridge will be used for controlling the direction of the robot as it locomotes on a planar surface.
