Mobile robot and method of operating thereof
First Claim
1. A method of operating a mobile robot, the method comprising:
- driving the robot according to a drive command issued by a remote operator control unit in communication with the robot;
determining a driven path of the robot from an origin;
after experiencing a loss of communications with the operator control unit, determining a retro-traverse drive command to maneuver the robot along a return path back to a communication location where the robot had established communications with the operator control unit;
driving the robot according to the determined retro-traverse drive command; and
in response to overshooting the communication location, driving the robot to the communication location by traversing the portion of the driven path that progressed past the communication location without re-traversing the entire return path back to the communication location.

Abstract
A method of operating a mobile robot includes driving the robot according to a drive command issued by a remote operator control unit in communication with the robot, determining a driven path from an origin, and after experiencing a loss of communications with the operator control unit, determining an orientation of the robot. The method further includes executing a self-righting maneuver when the robot is oriented upside down. The self-righting maneuver includes rotating an appendage of the robot from a stowed position alongside a main body of the robot downward and away from the main body, raising and supporting the main body on the appendage, and then further rotating the appendage to drive the upright main body past a vertical position, causing the robot to fall over and thereby invert the main body.

12. A method of operating a mobile robot, the method comprising:
-
driving the robot according to a heading issued by a remote operator control unit in communication with the robot; upon detecting a deviation between a drive heading of the robot and the issued heading, determining a heading correction; and driving the robot according to the determined heading correction until the drive heading matches the issued heading. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
