News Release

Bedford, Mass., July 23, 2008 – iRobot Corp. (Nasdaq: IRBT) today announced it received an additional order under its current contract with the U.S. Army Program Executive Office for Simulation, Training, and Instrumentation (PEO STRI) totaling $17.5 million.

This is the fourth order under the $286 million Indefinite Delivery/Indefinite Quantity (IDIQ) xBot contract, which will deliver more than 220 additional robots to the Army by December 31, 2008. Orders with PEO STRI now total $44.5 million.

“Robots will continue to support soldiers in theater as unmanned systems increase critical mission effectiveness,” said Joe Dyer, president of iRobot Government and Industrial Robots. “The continued investment from the U.S. Army is a clear symbol of iRobot’s growing position as a supplier of critical battlefield equipment.”

The robot included in this contract is the PackBot 510 with FasTac Kit, which will help warfighters investigate suspicious objects, identify roadside bombs and other improvised explosive devices (IEDs), as well as uncover unexploded ordnance while keeping soldiers in theater at safe distances.

The PackBot 510 represents the next generation of PackBot technology that increases overall robot speed by 30 percent, accelerates travel over tough terrains of rocks and mud to speeds of up to 5.6 miles per hour, and supports climbing grades of up to 60 degrees. Light enough for deployment by one warfighter, but strong enough to carry 30 pounds the PackBot 510 leverages a digital modular architecture to support interchangeable, modular payload capabilities that address specific missions.

iRobot has delivered more than 1,500 PackBot robots that make a difference everyday by conducting dangerous missions that keep warfighters out of harm's way.
