- Lightweight, super-strong robots will lead human soldiers
into battle within 10 years -- at least according to iRobot.
-
- The robots, called small unmanned ground vehicles, or
SUGVs, will detect the presence of chemical and biological weapons, identify
targets for artillery and infantrymen, and ferret out snipers hiding inside
urban buildings. Today, humans mainly perform these tasks, often becoming
the first casualties of battle while looking for snipers or explosives.
-
- The SUGV (pronounced "sug-vee") will be a smaller
and lighter version of the PackBot, a 42-pound robot with tanklike rubber
treads designed by iRobot, a company based in Burlington, Massachusetts.
-
- IRobot, which was co-founded by Massachusetts Institute
of Technology roboticist Rodney Brooks, is the same company that developed
the Roomba robot vacuum cleaner.
-
- American soldiers are already using PackBots to search
inside caves in Afghanistan, and to remove roadside bombs in Iraq. A PackBot
proved its worth last week when it uncovered a bomb in Iraq and was destroyed
in the process.
-
- "One robot was blown up," said retired Vice
Adm. Joe Dyer, general manager of iRobot's government and industrial robotics
division. "That was a cause for celebration, because the robot saved
the life of a soldier."
-
- Urban warfare is dirty business, as the Army's experience
in Fallujah, Iraq, shows. Soldiers piling into narrow doorways are particularly
vulnerable to gunfire, and snipers are hard to spot once their shots begin
echoing throughout apartment blocks.
-
- But soldiers in the future, the Army hopes, will be able
to pull SUGVs from their backpacks and drop the robots through the windows
of buildings where enemies may be hiding.
-
- IRobot wants to bring the weight of the SUGV down to
25 pounds (not including its robot arm) while retaining sturdiness. The
PackBot, for example, can be dropped onto concrete from a height of about
6 feet. The company said one PackBot survived a 30-foot drop from a cliff.
-
- As they do with PackBots today, soldiers will operate
the SUGVs remotely, with rugged laptops and handheld computers, and through
wireless or fiber-optic links. Targeting systems, chemical and biological
sensors, and other devices, which are being developed by Raytheon, will
operate at the end of the SUGV's robotic arm.
-
- SUGVs will be one of 18 networked components in the U.S.
Army's $14.7 billion Future Combat Systems program, which will include
manned and unmanned ground and aerial vehicles, as well as new sensor systems.
IRobot this week signed a $32 million deal with leading contractors to
develop SUGVs.
-
- Future Combat Systems program leaders envision a future
of highly mobile and flexible "units of action," consisting of
manned and unmanned combat vehicles.

will be able to deploy these units "from bases in the United States
directly into the open desert," said retired Lt. Gen. Daniel Zanini,
corporate vice president at Science Applications International."It
will ensure the U.S. remains the world's dominant force for land combat."
-
- Science Applications International, along with Boeing,
is the lead systems integrator for Future Combat Systems.
-
- Some of the robots that are being developed may also
be used to shoot at human targets, iRobot suggested. But the company said
SUGVs will provide advanced reconnaissance first. The company does not
want to be seen as putting human soldiers out of business.
-
- Robot vision systems have serious limitations, and the
risk that a robot might kill an innocent civilian is too great, said iRobot
CEO Colin Angle.
-
- But Angle did not rule out the eventual use of weapons
on robots, and noted that Raytheon is developing a targeting system for
the SUGV.
-
- "We're not using these robots to hand out flowers,"
Angle said.
