Abstract:

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.
