2. Introduction To UGV
• An unmanned ground vehicle (UGV) is a vehicle that operates while
in contact with the ground and without an on-board human presence.
• UGVs can be used for many applications where it may be
inconvenient, dangerous, or impossible to have a human operator
present.
• Generally, the vehicle will have a set of sensors to observe the
environment, and will either autonomously make decisions about its
behaviour or pass the information to a human operator at a different
location who will control the vehicle through teleoperation.
3. Contd..
• Though, when seeing the present trend in market of robotic
appliances UGV’s are not so famous.
• But we must know that there are some organizations in which UGV’s
are irreplaceable and used very frequently
• One thinks that instead of buying a UGV why not buy a
Quadcopter/Drone with same features but we should know that
Quadcopter are a bad choice for indoor operations.
• Quadcopter having the same features as that of Pibot are 3 times
more costlier than that of Pibot
4. Project Overview
• The basic idea behind Pibot is to built a robot that can be reachable in
the smallest place possible in order to carry on rescue and
surveillance operations which can be controlled from anywhere over
the internet.
• In addition to all this the Pibot will be totally customizable so that a
normal user can add his/her desired features without any hassle.
• The cost of the Pibot will be less than that of the similar
products(which are very few) available in the market.
• Pibot will be able to give all the functionalities of the computer(in
other words numerous ) as well as that of the UGV.
5. Features Of Pibot
• Moving easily on rough terrains.
• The controlling Platform of the Pibot will be available for most of the
platforms .
• The camera would be able to rotate in X as well as inY axis.
• The camera movement can be controlled remotely.
• The run time of Pibot would be around 2 to 3 hours minimum.
• Pibot will be having a GeolocationTracking feature which will enable
us to track it’s location on a map.
6. Contd..
• Pibot will feature a light detection sensor which would automatically
turn on the led installed on the Pibot if it sense’s less light conditions.
• Pibot will support audio streaming i.e. we can even send/receive
sound from/to Pibot.
• Owing to its small size Pibot will be able to go in small places easily.
• There would be a tagging feature on the map i.e. the user will be able
to tag the location which needs further attention (disaster
management).
• The camera stream from the Pibot will be recorded on the controlling
device.
7. Contd..
• Pibot will be easily customizable by the normal user who can add any
extra sensors/hardware/functionalities very easily.
• Pibot will be able to follow any movement autonomously if the given
feature is enabled.
• It can also send a message/notification to the user in case any
movement is detected.
• Pibot can be synced with other Pibot’s or Raspberry Pi enabled
Quadcopter.
• Pibot’s software can be easily updated through Internet so the Pibot
will never be outdated.
8. Parts Used/Required
• Raspberry Pi 2 Model B: The Raspberry Pi in case of
this projects works as a server and as a peripheral such
as camera, GPS module controlling device having a
processor of 900 MHz and a RAM of 1 GB. Apart from
this the Raspberry Pi will be helpful in providing various
software based features.
• Arduino Uno: It will be interfaced to the Raspberry Pi
through serial communication which would be used for
controlling motors and other sensors and leds.
• Camera:This will be used to provide live stream of the Pibot’s
position to its controller.
• GPS Receiver: It will be connected to the pi and will be used
to track the exact location of the Pibot in terms of latitude and
longitude which could be plotted on a map and it can be
further used in autonomous navigation.
9. Contd..
• Power Bank: A Power Source of 5v & 10000 Mah
used for powering the raspberry pi and the USB
Hub.
• Li-ion Rechargeable Battery: A Power Source of
12v &11000 MAH for powering Dc motors only.
• 12v DC Motors: 6 12v dc high torque motors for the
movement of the Pibot.
• 4/7 Port Powered USB Hub:As there are multiple
USB devices connected to the Pibot this powered
USB hub will be required to power up some of these
USB devices externally and thus reducing the load
on the raspberry pi.
• Two axis tilt and rotate servo pan:This will be used
to mount the camera on it hence providing two axis
movement to the camera.
10. Progress Done So Far
• Interfaced Raspberry Pi and Arduino Uno and built a robot that can be
controlled over local network/internet.
• Developed a desktop based application for controlling the robot and
viewing a live stream from the robot.
• Added a camera on the robot.
• Added motion detection feature in the robot
• Integrated Google Maps API in the desktop based application for
Geo-LocationTracking.
12. Target Customers
• Pibot can be useful under various categories such as:
• ForVarious Government Organizations:
• These vehicles can benefit the military with the ability to send these robot ahead of platoons
to examine the terrain they are about to enter.
• It will allow the soldiers to spot the hidden enemies.
• It can used to spot the hidden bombs.
• It can be used to defuse any explosive hence avoiding the possibility of a soldier being killed
by manually defusing the explosive.
• It can also be used to provide supplies to the solider in combat.
• Can be used to seek survivors where it’s not possible for a human to reach in case of any
natural calamities such as earthquakes.
• Can tag the position of survivors on a map so they can be rescued as soon as possible.
• It can be used to setup surveillance in those places where it is not possible for a human being
to be there
13. Contd..
• For Other Individuals/Organizations :
• Pibot can be used to survey different part of one’s organization without actually being there.
• It could be used for home security and surveillance.
• For the technology loving people it can be one of their gadgets which they want to use and
customizable as it will be the cheapest product in it’s segment.
14. Pibot Under Large Scale Production
• The total cost required to build a prototype will be approximately
Rs.25000/- but keeping in mind that on large scale production all the
hardware will be available at a cheaper cost it’s manufacturing cost
will be not more than Rs.20000/-.
