Robots battle for military prize
By Jonathan Fildes, Science and Technology reporter, BBC News
From http://news.bbc.co.uk/1/hi/technology/6919271.stm
The Grand Challenge has been set up to meet the needs of urban warfare
For two weeks during the summer of 2008, an army of autonomous robots will march across the Wiltshire countryside.
The machines will compete in the UK Ministry of Defence Grand Challenge, a competition to find new technology to support ground troops in urban areas.
Winning designs include a swarm of miniature helicopters and a host of sensor-laden unmanned aerial vehicles.
"Technology plays a huge role in our forces, It often makes the difference between success and failure - and sometimes life and death," said Defence Procurement Minister Lord Drayson on announcing the winners.
"The challenge is to produce a semi-autonomous system that can detect, identify, monitor and report a range of physical threats in an urban environment."
The winner of the competition will win the R J Mitchell Trophy, named after the "father of the Spitfire" WWII fighter plane and also funding from the Ministry of Defence (MoD).
Target lock
In total, the challenge received 23 proposals from firms and research institutions.
Grand Challenge judges have now chosen to fund six of them to compete in the finals; a further eight teams have entered the challenge with private funding. Fourteen teams have now been picked as finalists to go head to head in a range of trials next year.
The competition, carried out in August 2008, will focus on the urban environment and will be carried out at Copehill Down, an army training centre on Salisbury Plain.
"There are going to be four categories of targets: an improvised explosive device; a sniper; some kind of four-by-four vehicle with a gun on it; and bunches of 'hoods' dressed in semi-military uniform carrying arms," Mike Martin, chief judge of the challenge, told the BBC News website.
The winner will not necessarily be the team that identifies all of the targets correctly, according to Mr Martin.
For example, a remote-controlled vehicle will lose points for needing input from a human operator.
"Something that is completely autonomous - you just launch it; it goes off, does its own thing and comes back and says unequivocally X, Y and Z are targets - would score maximum points," said Mr Martin.
Urban challenge
The Grand Challenge will deliberately focus on robots that can aid troops in the urban environment, an increasingly common battle arena. Built during the Cold War and modeled on an East German village, the mock-up settlement will be swept by the teams for possible threats.
Copehill was built during the Cold War to teach urban fighting
"Urban operations are both very important and they're becoming more difficult to carry out safely," said Lord Drayson. "The challenge of the urban environment is the degree to which you have this unstructured clutter and the unexpected."
"This is an environment which is growing in density and complexity on a daily basis."
As well as dealing with the sheer complexity of having to differentiate between a sniper and an innocent civilian leaning out of a window, the vehicles will also face a number of environmental hazards.
Of particular concern to the teams, which have been allowed to map the Copehill site, are the wind, trees and the near-invisible overhead cables that criss-cross the site.
"They could be a problem for us because we might be flying quite low, but we should be able to pick them up on the cameras," said Jeremy Old of Team Dragonfly.
The privately funded group has proposed a 2m-long, lightweight, hovering vehicle equipped with a zoom lens and with thermal or infrared imaging.
"We can fly quite slowly which will give us time to react, but it all needs thinking about."
Numbers game
The teams now have 12 months to build their prototypes.
Some have relatively simple designs, based around a single vehicle.Major General John Cooper added: "The threat you are facing is not only small arms, in terms of direct fire, but also potentially anti-tank [weapons]... and increasingly complex improvised explosive devices.
The winner of the Challenge will receive a trophy and funding
Barnard Microsystems, for example, plans to adapt an unmanned aerial vehicle (UAV ) it has designed to survey oil pipelines in remote areas.
"The platforms have got autonomous threat detection sensors on them based on visual, thermal and radar," explained Dr Julia Richardson, head of the team.
One of the most innovative designs was proposed by a team from Swarm Systems.
Its proposal consists of eight to 10 "dinner-plate sized" quad-rotor helicopters which would be able to fly in and out of buildings.
"There is only so much information you can capture from one vehicle," Stephen Crampton, the head of the team, told the BBC News website.
Equipped with high-resolution cameras, the swarm will use numbers to its advantage.
"You can get images from different points of view, which is often very important because something you can see from one angle, you can't from another," said Dr Owen Holland, another member of the team.
Others, such as team Stellar has proposed a multiple vehicle approach. Its Saturn (Sensing and Autonomous Tactical Reconnaissance Network) proposal consists of two different UAVs and an unmanned ground vehicle (UGV).

GFS enters new flying-saucer UAV in UK MoD's Grand
Challenge
By Rob Coppinger
DATE: 8 February 2008
SOURCE: Flight
International
GFS Projects is to participate in
the UK Ministry of Defence's Grand
Challenge competition in August using a new 800 mm diameter
Coanda-effect vertical take-off and landing unmanned air vehicle that will
co-operate with a robotic ground vehicle.
The UAV will have a carbonfibre structure provided by the UK composites specialist Lola Group, a
two-stroke engine running on an oil/petrol mix and a maximum take-off weight of
18.5 kg. Payload capacity is 4 kg and maximum fuel load 2.5 kg. Test
flights are expected at the end of April.
"We are working with [product engineering
specialist] MIRA on the MoD's Grand Challenge and we are talking to a raft
of people about investment. We have completed the first contract with the [US
military]," says GFS founder Geoff Hatton. MIRA will provide the robotic ground
vehicle for the challenge and Hatton is meeting with the US military to discuss
a possible follow-on contract.
Air blown over the curved surface of the saucer-shaped vehicle generates lift
as a result of the Coanda
effect. Gust response is still an issue, Hatton says, and its resolution is
linked closely to the vehicle's mass. The heavier the UAV, the more effective its
gust resistance.

Silicon Valley Team
- Silicon ValleySystems Limited
- IDUS Consultancy
- Moonbuggy Limited
- Kingston University
- Reading University
- Bruton School for Girls
They are offering
a combination of fixed, ground and air platforms with optical, laser range
finder and acoustic sensors.
The following from an advertisement (see http://www.jobs.ac.uk/jobs/JN363/Researcher/) for a position at
Kingston University gives some idea of their contribution:
Researcher
Visual Surveillance
Computing, Information Systems and Mathematics, Digital Imaging Research
Centre
The successful candidate will contribute to the development of image
processing and computer vision methods, to be deployed in the system to be
demonstrated. Such methods will extract features from the available video
streams derived from fixed and moving camera platforms and output these and
other data that are indicative of the level of threat.
The work will include both laboratory and field experiments to evaluate
existing and innovative approaches. A knowledge of programming using C/C++ in
this application domain is essential. A PhD in Computer Science or a related
discipline, or work with embedded or real time systems design, would be
desirable.
From http://technology.newscientist.com/channel/tech/dn13796-english-village-to-be-invaded-in-spybot-competition.html
A third team, Silicon Valley, has opted to rely less heavily on autonomous
vehicles. They have used off-the-shelf technology for the hardware as much as
possible, and focused more development onto image recognition and analysis
software.
"If you can automate that part, then you have a useful tool," explains team
leader, Norman Gregory. "What we intend to do is deploy various platforms,
depending on what the scenario is."
The team will use a mixture of ground and air-based vehicles, although the
team is not yet releasing the exact details. The main ground vehicle is the size
of a ride-on lawnmower and can be GPS-guided or
remotely directed by a human.

Micro Air Vehicle (MAV) persistence in the urban environment
- from http://www.bluebearsystems.com/Default.asp?page=387

This project is the third MAV project awarded to BBSR, supported by the Research Acquisition Organisation, UK MOD. The work uses our rapid prototyping approach to design, integrate and flight
test new and emerging technologies in the following areas:
- planform configurations
- flight control algorithms and flight control modes
- flight and surveillance sensors
- power sources

-from http://technology.newscientist.com/channel/tech/dn13796-english-village-to-be-invaded-in-spybot-competition.html
One funded team, the Stellar
Consortium, uses two aerial robots and one ground-based one.
A 3m wing-span unmanned air vehicle (UAV) will fly 65 metres above the
village and use cameras to gather wide-area surveillance used by software to
direct a smaller, 1m UAV flying at 20 metres, and an unmanned ground vehicle
(UGV), (see image, middle right).
Those two vehicles use thermal, visual, and radar sensors to make more
detailed observations that can be reported back to the base station.
"Physically, the vehicles all have to be launched by someone," explains Julia
Richardson, Director of Stellar Research, "but after that, the mission-planning
software hosted at the ground station takes full control."

Owl swarm
A team called Swarm Systems uses more robots. "We need to gather as much sensory
information as possible," says team leader Stephen Crampton, "so we're using
eight vehicles. And we're going by air because it gives you more viewing
angles."
Dubbed "Owls", their battery-powered, Frisbee-sized vehicles weigh under a
kilogram and have four small propellers (see image, right). Able to hover and
dart like birds, they are GPS-guided and communicate with one another, and the
base station, using Wi-Fi. Each Owl carries a trio of 5 megapixel cameras.
"Without giving too much away, the processing power on board each of these
vehicles is pretty impressive," adds Crampton. "They could run full-blown
Windows Vista."

Team i-Spy
A combined short
range and medium range UAV system to deliver optical and thermal sensing.
A TECHNOLOGY whiz kid from Camden Town could change the face of warfare if his
ideas are adopted by the armed forces. Tom Foran is entering the MoD's
Grand Challenge to find new ways of detecting threats to its troops. The
20-year-old and his team of fellow students from Middlesex University are
designing a UAV (unmanned autonomous vehicle) that will fly above the ground
spotting snipers, bombs and enemy vehicles. The hi-tech spy plane will be
mounted with thermal imaging equipment and robotic cameras and will relay
information back to base without the need for a pilot. The York Way
resident said: "Other teams entering the challenge are designing ground-based
UAVs. But we are developing a flying vehicle as the air is probably the safest
place to be in a battlefield. "Being airborne will also give the best
viewing angles and provide the most detailed information."
The five-man team, including lecturer Dr Stephen Prior and a PhD student, expect
the project to cost more than £30,000. Dr Prior said: "We are now
seeking partners to help fund the development of this exciting work."
