CONTENTS

What is an Unmanned Ground Vehicle?

• It is an exploration vehicle.• Unmanned Ground Vehicle is a Robot or

called as Rover. It is called as UGV.• It is used in the field of Military applications,

Space applications, Navy, Crew, Gaming etc.

INTRODUCTION

PROJECT ABSTRACT

Command Control mode:• The UGV is controlled by commands given from the base

station (Computer/Laptop). [Manual mode]Autonomous mode:• Capable of travelling from point A to point B without

human navigation commands.• Adjust strategies based on surroundings using obstacle

detection algorithms.Arm Controlled mode : The UGV is controlled by using commands based on

hand movements.

FLOW CHARTARMCON SIDE UGV SIDE

The command is given from the base station that is human will control with his wrist.

Human himself is the base station. Control Signals from hand are Pitch and Roll

which is up, down and right, left movements. Rover senses the directions given by human

using the Arduino hardware and software. Now the Control signals translated to

equivalent functions.

FUNCTION OF PITCH AND ROLL

Used in new explorations. Military purposes Bomb Disposal Search and Rescue Gaming Satellite communication Vehicle tracking

APPLICATIONS

RESULTS

Successfully built a stand-alone rover capable of both manual and autonomous modes of control.

Added a rotating camera platform that can target the enemy with/without human control.

Successfully implemented features including motion tracking, obstacle detection, path planning , gesture control and GPS.

FUTURE ENHANCEMENTS

• Additional sensors such as Passive infrared sensors, thermal imaging, Gas sensor, can be added to enhance the capabilities of the UGV.

• Secure satellite links for communication increases the security of UGV operation.
