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.

Autonomous behaviors for a remote vehicle

The present teachings provide a method of controlling a remote vehicle having an end effector and an image sensing device. The method includes obtaining an image of an object with the image sensing device, determining a ray from a focal point of the image to the object based on the obtained image, positioning the end effector of the remote vehicle to align with the determined ray, and moving the end effector along the determined ray to approach the object.

Auto-reach method and system for a remote vehicle

Auto-reach method for a remote vehicle

A system and method for allowing an operator to switch between remote vehicle tele-operation and one or more remote vehicle autonomous behaviors, or for implementing remote vehicle autonomous behaviors. The system comprises an operator control system receiving input from the operator including instructions for the remote vehicle to execute an autonomous behavior, and a control system on the remote vehicle for receiving the instruction to execute an autonomous behavior from the operator control system. Upon receiving the instruction to execute an autonomous behavior, the remote vehicle executes that autonomous behavior.

Autonomous behaviors for a remove vehicle

A method comprising running a persistent self-righting behavior comprising sensing an orientation of the remote vehicle and performing a progression of flipper movements until the remote vehicle is righted, and performing a retrotraverse behavior comprising: generating a list of time stamped waypoints separated by at least a minimum difference in time and distance; storing the list of time stamped waypoints in the memory; and generating, using a control system, a current return path interconnecting previously-traversed waypoints in reverse order of timestamps upon losing communication with the operator control unit or upon receiving a command from the operator control unit.

A method for enhancing operational efficiency of a remote vehicle using a diagnostic behavior. The method comprises inputting and analyzing data received from a plurality of sensors to determine the existence of deviations from normal operation of the remote vehicle, updating parameters in a reference mobility model based on deviations from normal operation, and revising strategies to achieve an operational goal of the remote vehicle to accommodate deviations from normal operation. An embedded simulation and training system for a remote vehicle. The system comprises a software architecture installed on the operator control unit and including software routines and drivers capable of carrying out mission simulations and training.

A system for allowing an operator to switch between remote vehicle tele-operation and one or more remote vehicle autonomous behaviors. The system comprises: an operator control unit receiving input from the operator including instructions for the remote vehicle to execute an autonomous behavior; a control system on the remote vehicle for receiving the instruction to execute an autonomous behavior from the operator control unit; and a GPS receiver, an inertial measurement unit, and a navigation CPU on the remote vehicle. Upon receiving the instruction to execute an autonomous behavior, the remote vehicle executes that autonomous behavior using input from the GPS receiver, the inertial measurement unit (IMU), and the navigation CPU.
