The Defense and Security business of iRobot has been acquired by Arlington Capital Partners, a private equity firm.

iRobot, the largest provider of ground-based robots to the Department of Defense, will operate independently under the name Endeavor Robotics.

"We are proud to form Endeavor Robotics and honored to continue delivering robotics that protect those in harm's way," said Sean Bielat, chief executive officer of Endeavor Robotics. "Our team is developing exciting new technology and we are actively reviewing acquisition opportunities that will propel our growth."

iRobot's -- and now Endeavor's product line -- is comprised of four classes of robots for warfighters and first responders: FirstLook, SUGV, PackBot and Kobra.

"As an independent company dedicated to tactical robotics, Endeavor Robotics will have new flexibility to meet the needs and protect the lives of our customers serving on the frontline and in dangerous environments," said Tom Frost, president of Endeavor Robotics. "We've always done our best work when we worked closely with our customers. Our new structure enables us to double down on that strategy.

"We believe that the future is in open architecture and collaborative solutions and we look forward to making that a reality."

Frost is the former senior vice president and general manager of iRobot's Defense & Security business. Bielat is the former iRobot Defense & Security executive officer.

The financial details of the acquisition were not disclosed.
