1) The document describes the development of a tele-operated unmanned ground vehicle (UGV) for metal detection that can be operated remotely from a ground station. 2) The UGV uses hardware components like an Intel Edison development board, motor driver, batteries, webcam and a metal detection sensor. It transmits video streaming via an MPEG server and can be controlled through a RESTful API. 3) The UGV has applications in bomb detection and hazardous material investigations to help military and security personnel operate safely from a distance. While it has limitations, the remote-controlled metal detector has the potential to save lives.

4. History
In October 1921 a working remote controlled car was
reported by the RCA's(Radio Corporation of
America) World Wide Wireless magazine. The car was
unmanned and controlled wirelessly via radio; it was
thought that the technology could someday be adapted
to tanks.

5. History
In the 1930s, the USSR developed Teletanks which was a
machine gun-armed tank. These tanks were remotely controlled
by radio from another tank. These were used in the Winter
War (1939-1940 ) against Finland. These tanks were also used at
the start of the Eastern Front after Germany invaded the USSR in
1941.

6. History(Contd.)
From 1942, the Germans used the Goliath tracked mine for
remote demolition work. The Goliath was a small tracked vehicle
carrying 60 kg of explosive charge directed through a control
cable.

7. RAB uses Portable Mine Detector
7
Portable Mine Detector is widely used for searching bombs , mines , IEDs
and other explosives in Bangladesh. RAB members are using this instruments
for a long period of time. For using this , the physical presence of operator is
mandatory.

portable mine detector (contd.)

9. Bangladeshi Military Operations
• The Bangladeshi Army sometimes visit in extremely rough
terrain to rescue someone or to observe an area for conducting
missions. This may cost their lives.

10. UGV vs Military Operations (Contd.)
10
For that kind of risky situations if they use tele-operated UGV , it can save
many lives. They can observe hostile area by operating the UGV from a
secure place. It can also detect weapon caches because it provides video
streaming.

11. Motivation
TALON is a lightweight, unmanned military robot. The robot isTALON is a lightweight, unmanned military robot. The robot is

15. Working Principles
• A battery of the metal detector activates the transmitter circuit (red) that passes
electricity down through a cable in to the transmitter coil (red) at the bottom.
• When electricity flows through the transmitter coil, it creates a magnetic field all
around it.
15

16. Working Principles(Contd.)
• Magnetic field makes an electric current flow inside metal object.
16

17. Working Principles(Contd.)
• This flowing electric current creates another magnetic field all around the
object.
• The magnetic field goes through the receiver coil (blue) .
• The magnetic field makes electricity flow around the receiver coil and up into
the receiver circuit (blue) at the top.

22. Services(Contd.)
22

23. Services
• Two Services are Used :
1. MPEG Server: The Moving Picture Experts Group (MPEG) is
the family of standards and file formats which are used in
digital video. This server were used to get video streaming
.Server sends a signal to the Webcam .Then we get the video
streaming.
2. Restful API: Representational State Transfer - can be used
over nearly any protocol, when used for web APIs it typically
takes advantage of HTTP. This was used for controlling the
car.
23

24. Applications
1. To detect bombs or IEDs.
2. Rescue operation is pretty dangerous for rescue team as well as rescue
dogs because the rescue operators don't know about the rescue
environment. For this situations the robot is effective.
3. Miners often has to go narrow and rough caves . By sending the robot
miners don’t need to risk their lives.
24

25. Limitaions
• It can only detect the metal but unable to find the type of
metal.
• It is unable to disarm bombs.
• We have used professional metal detection components, but
due to wire connections problem sometimes this vehicle give
false information.
• This vehicle still not capable of donig rescue and recovery
missions.
25

26. Conclusion
>>Our ultimate goal is to help the military or national security
personnel to do their daily patrol monitoring, bomb detecting job
safely.
>>On that purpose, we have build a tele-operated UGV metal
detector using two services like MPEG Server and Restful API.
>>Despite having some limitations, our car will be a helping
hand to save many lives.
26

27. Future Work
Besides Metal Detection it can be also implemented :
1. Add a parking sensor and radar to ensure the car security in
parking place.
2.Use a humidity sensor to measure the humidity of certain area.
3.Can be used in irrigation.
4.Will be possible to make rescue and recovery missions like
demining, watering in burning buildings or place.
5.Using GPS to scan the topography ahead, predictive satellite-
aided transmission monitors driving behaviour and matches it to
the road conditions.
