4.  What is an Unmanned Ground Vehicle?
• It is an exploration vehicle.
• Unmanned Ground Vehicle is a Robot. It is
called as UGV.
• It is used in the field of Military applications,
Gaming etc.

5.  PROJECT ABSTRACT
Command Control mode:
• The UGV is controlled by commands given from the
base station(Computer/Laptop).
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.

13.  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 Arduino hardware and software.
 Now the Control signals translated to
equivalent functions.

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

16.  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.

17. • 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.
