A mobile cleaning robot can include a robot body, a bumper, and a bumper impact system. The bumper can be connected to and supported by the robot body. The bumper impact system can include a first sensor connected to the body in a first orientation with respect to the body and the bumper. The bumper impact system can include a second sensor connected to the body in a second orientation with respect to the body and the bumper different from the first orientation. The first sensor and the second sensor can together be configured to sense an impact region of the bumper based on a magnitude and a direction of movement of the bumper relative to the robot body.

Autonomous floor-cleaning robot having obstacle detection force sensors thereon and related methods

A mobile robot can include a robot body; a drive system supporting the robot body above a floor surface for maneuvering the robot across the floor surface; a bumper frame on a front periphery of the robot body, the bumper frame supported by the robot body; and a bumper impact system comprising: a first sensor at a first orientation with respect to the bumper frame that is configured to generate a first signal in response to a magnitude and a direction of movement of the bumper frame relative to the robot body; a second sensor at a second orientation with respect to the bumper frame that is configured to generate a second signal in response to a magnitude and a direction of movement of the bumper frame relative to the robot body, the second orientation being different from the first orientation; and a processor.
