The MARCbot is a robot that U.S. Army soldiers are currently using to help identify improvised explosive devices (IEDs) in Iraq. It was developed by Exponent for the U.S. Army’s Rapid Equipping Force to meet a critical operational need identified during combat operations as observed by Exponent employees in theater. Based upon the first Exponent robots sent to Afghanistan in 2002, the first improved MARCbot IIs for IED sweeps were initially sent to Iraq in May 2004. Spiral improvements were made in direct response to soldier feedback obtained from IED sweep missions, resulting in the current MARCbot IV configuration.

Soldiers performing IED sweeps use this remote observation platform to inspect suspicious objects from a distance instead of walking or driving near the objects. The MARCbot is designed to effectively meet the needs of these soldiers during the sweeps.


  • Remote observation distance greater than 100 meters
  • Low-light camera and LED arrays provide nighttime mission capability
  • Pan/tilt camera can be raised to a height of 3 feet and tipped forward as far as 1.2 feet for viewing the tops of boxes, and looking into cans and over burlap sacks
  • Platform is able to navigate most curbs
  • Powered by military standard x90 batteries (BB-2590, BB-390) instead of expensive, proprietary batteries
  • Low-cost platform intended as a disposable-type asset to address otherwise problematic technical support/logistics of complex, expensive robots.

User Feedback

If the IED blows up, the only thing that’s hurt is the robot, and we can easily replace a robot.

I want one of these for all of my combat vehicles.
—Company Commander, Baghdad, Iraq

It allows us to get eyes on. You can see a lot with binoculars and everything else, but with this, you’re right on it.
