A method includes maneuvering a robot in (i) a following mode in which the robot is controlled to travel along a path segment adjacent an obstacle, while recording data indicative of the path segment, and (ii) in a coverage mode in which the robot is controlled to traverse an area. The method includes generating data indicative of a layout of the area, updating data indicative of a calculated robot pose based at least on odometry, and calculating a pose confidence level. The method includes, in response to the confidence level being below a confidence limit, maneuvering the robot to a suspected location of the path segment, based on the calculated robot pose and the data indicative of the layout and, in response to detecting the path segment within a distance from the suspected location, updating the data indicative of the calculated pose and/or the layout.

Localization and mapping using physical features

A cleaning robot includes a chassis, a drive system connected to the chassis and configured to drive the robot, a signal generator and sensor carried by the chassis, and a controller in communication with the drive system and the sensor. The signal generator directs a signal toward the floor surface. The sensor is responsive to reflected signals from the floor surface. The controller controls the drive system to alter direction of the robot responsive to a reflected signal indicating an edge of the floor surface.

Mobile robot area cleaning

A method of object detection for a mobile robot includes emitting a speckle pattern of light onto a scene about the robot while maneuvering the robot across a work surface, receiving reflections of the emitted speckle pattern off surfaces of a target object in the scene, determining a distance of each reflecting surface of the target object, constructing a three-dimensional depth map of the target object, and classifying the target object.

Mobile human interface robot

A mobile robot including a robot body, a drive system supporting the robot body, and a controller in communication with the drive system. The robot also includes an actuator moving a portion of the robot body through a volume of space adjacent the mobile robot and a sensor pod in communication with the controller. The sensor pod includes a collar rotatably supported and having a curved wall formed at least partially as a surface of revolution about a vertical axis. The sensor pod also includes a volumetric point cloud sensor housed by the collar and observing the volume of space adjacent the robot from within the collar along an observation axis extending through the curved wall. A collar actuator rotates the collar and the volumetric point cloud sensor together about the collar axis.
