The 310 small unmanned ground vehicle is a man-portable robot for dismounted mobile operations, including explosive ordnance disposal.
IRobot said the contract received from the U.S. Army's Robotic Systems Joint Program Office includes an initial $2 million order for spares to be delivered in the first quarter of next year.
"iRobot is pleased to continue its partnership with the Army to provide world-class robotic capabilities that help keep our warfighters out of harm's way," said Frank Wilson, senior vice president and general manager of iRobot's Defense & Security business unit.
The company said it also received a separate $3.7 million order from the RSJPO for heads-down SUGV controllers. The handheld controller includes a 5.6" LCD display screen that is sunlight readable.
The controllers will be delivered by the end of this year.
"We are delivering the heads-down controller in response to specific requests from the field," Wilson said. "This easy-to-use controller provides the operator with a high degree of situational awareness while conducting dangerous missions."
