In addition to being blown up, a combination of heat, sand, wind, and rain also can cause problems for robots. At a cost of anywhere from $4500 for the cheapest "Throwbot," to more than $100,000 for a high-end EOD robot, there's a lot of pressure and effort to repair the scarce and always in demand machines as quickly as possible. Two repair shops have crews on-call around the clock, with technicians provided from the Army, Navy, and Marines, as well as some civilian contractors. Spare parts are shipped in to Baghdad via FedEx or DHL. - Doug Mohney.
With over 1500 deployed robots in Iraq and Afghanistan, with twice as many in service by the end of the year, the U.S. Army has set up a facility in Baghdad for in-theatre robot repairs. As of September 2005, the facility is averaging around 50 repairs a week (up from 20-30 in the spring) and offers a four hour repair guarantee. If it can't be fixed in four hours, the troops leave with another working robot. All a "customer" has to do is to bring in their broken robot - or in the case of a fatal encounter with an IED, the remains of the robot. Even if the robot isn't fixable, usable parts are scavenged for use in other repairs.
