ABSTRACT

The objective of the project is to build a tank car that can be controlled by

gesture wirelessly. User is able to control motion of the tank by wearing the

controller glove and performing predefined gestures. This tank can detect block

objects and stop automatically in addition; feedback messages are sent to the

controller and warn the user by a vibration motor. This project provides a basic

platform for much potential application such as a wireless controlled car racing

games, gesture human-machine interfacing, and etc.

For this project, AT89C2051 microcontroller and Accelerometer are

employed for the controller; AT89s52, Dual H-bridge chip are employed for the

controlled tank. A pair of RF transmitter &receiver module is used to communicate

between the controller and tank.

This tank can detect block objects and stop automatically in addition,

feedback messages are sent to the controller and warn the user by a vibration

motor.

ACKNOWLEDGEMENT

It gives us immense pleasure to express our gratitude to Prof.V.B.KANANI, our guide

who provided us constructive criticism and a positive feedback during the preparation of this

project.

We indebted to Prof.C.H.VITHLANIHead of Department Electronics &

Communication Engineering and other teaching and non-teaching staff who were always there

whenever we needed any help. Without them and their co-operation, guidance in this project

work would have been inevitable and their presence behind us is totally indispensable.
