There are more than 2,000 ground robots fighting alongside flesh-and-blood forces in Afghanistan, according to Lt. Col. Dave Thompson, the Marine Corps’ top robot-handler. If his figures are right, it means one in 50 U.S. troops in Afghanistan isn’t even a human being. And America’s swelling ranks of groundbot warriors are being used in new, unexpected, life-saving ways.
But there’s one small problem: however numerous, these rolling and crawling robots are still pretty stupid. And there’s not much hope they’ll get any smarter anytime soon.
Groundbots first made inroads among bomb-disposal units. The human bomb-techs could take cover and steer in a remote-controlled Talon or PackBot to disable a dangerous explosive device. But a third of the 1,400 fresh ground bots deployed to Afghanistan in 2009 and 2010 weren’t for EOD, Thompson pointed out during a presentation at a Washington, D.C. trade show “Robots are not just for explosive ordnance disposal teams anymore … They [ground troops] are using them in ways we never expected.”
For instance, at least one unit sent its four-wheeler-size M-160 — a tracked vehicle fitted with a “flail” for detonating buried mines — to scout ahead of a (manned) Husky bomb-detecting vehicle. Route-clearing for the route-clearer, if you will. Thompson played a video that “showed a powerful roadside bomb destroying the M160,” National Defense reported. “That would have otherwise been the Husky and its occupants,” the magazine helpfully pointed out.
Bots are also being used to inspect vehicles approaching checkpoints, Thompson explained. Many other uses for unmanned ground vehicles are classified, he added.
Thompson seems bullish about groundbots’ prospects, but other military robotics engineers have expressed their disappointment. For all the growing popularity and utility of America’s robot soldiers, they’re still way too dumb to do much of anything on their own.
