Military and consumer robot manufacturer iRobot Corp. in Bedford will unveil a new product Tuesday intended for the health care industry as it diversifies its product line in preparation for looming defense cuts.

The 5-foot-4-inch, 140-pound “telemedicine” robot will be produced in partnership with InTouch Health of Santa Barbara, Calif., a maker of in-hospital robots, and is designed to help patients with health emergencies get more rapid treatment from specialists — especially at night, when hospital staff levels are lower, the company said.
