Abstract
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.
