Abstract: A method of operating a remote vehicle configured to communicate with an operator control unit (OCU) includes executing a click-to-drive behavior, a cruise control behavior, and a retro-traverse behavior on a computing processor. The click-to-drive behavior includes receiving a picture or a video feed and determining a drive destination in the received picture or video feed. The cruise control behavior includes receiving an absolute heading and velocity commands from the OCU and computing a drive heading and a drive velocity. The a retro-traverse behavior includes generating a return path interconnecting at least two previously-traversed waypoints of a list of time-stamped waypoints, and executing a retro-traverse of the return path by navigating the remote vehicle successively to previous time-stamped waypoints in the waypoints list until a control signal is received from the operator control unit.

Abstract: An operator control unit has a user interface that allows a user to identify a mode of display and interaction that narrows the user's options for his next interaction with the user interface. The user interface utilizes portals to transition between environments such as indoors to outdoors, outdoors to indoors, different rooms of a building, and different floors of a building, the portals representing one or more of stairways and doors, and being used in remote vehicle path planning as waypoints that may require execution of predetermined behaviors.
