The US Navy has awarded two indefinite-delivery, indefinite-quantity (IDIQ) contracts to iRobot's Defense & Security business unit.
Awarded by the Naval Surface Warfare Center, Indian Head Explosive Ordnance Disposal Technology Division, the contracts have a combined total ceiling of $96m.
As part of this development, iRobot has received initial orders worth $7.9m.
iRobot Defense & Security business unit senior vice-president and general manager Tom Frost said: "Our family of robots are smart, light, rugged and easy to use.
"We take pride in the role they play to keep our service members safe, and we remain committed to ensuring the US Navy's MTRS fleet is equipped with the latest in robotic technologies to combat threats that persist globally."
With a total ceiling of $46.7m, the first IDIQ contract covers support services, upgrades and spares for man-transportable robotic system (MTRS) MK1 robots.
Under this contract, iRobot received an initial order worth $7.5m and work is scheduled to be completed by September next year.
The second, multi-year IDIQ contract, worth $49.1m, involves the production of new MTRS MK1 robots, depot-level repair parts, spares, consumables and approved accessories to support configuration management and engineering enhancements.
The company has now received an initial order valued at $374,000 and work under this order is expected to be completed by September next year.
In August, iRobot secured an order from the US Navy to deliver its model 110 FirstLook robots and accessories.
In a separate development, the company received a contract from the US Marine Corps Systems Command to deliver 75 small unmanned ground vehicles (SUGV).
