Abstract

A robotic system for fueling or charging a vehicle having a vehicle connector, the robotic system including a robotic arm having a plurality of sequentially arranged articulated links and at least one group of operating cables extending from a proximal end of the arm to terminate at a control link, for controlling the position of that link, the cables each having a path comprising a passage in each successive more proximal link for closely receiving the cable, a flexible conduit operably connected with the robotic arm for delivering a fluid or an electrical current, respectively, to a vehicle, the conduit being connected to a source at a first end and a delivery connector at a second end, and a control system for operating the robotic arm and the hose or cable, wherein the control system directs the robotic arm to engage the vehicle connector with the delivery connector and, upon engagement of the vehicle connector and delivery connector, the control system relaxes the robotic arm to an under-constrained condition.

First claim

What is claimed is:

1. A robotic system for fueling or charging a vehicle having a vehicle connector, comprising:
a robotic arm having a plurality of sequentially arranged articulated links and at least one group of operating cables extending from a proximal end of the robotic arm to terminate at a control link, for controlling a position of the control link;
a flexible conduit operably connected with the robotic arm for delivering a fluid or an electrical current, respectively, to a vehicle, the flexible conduit being connected to a source at a first end and a delivery connector at a second end; and
a control system for operating the robotic arm and the flexible conduit;
wherein the control system directs the robotic arm to engage the vehicle connector with the delivery connector and, upon engagement of the vehicle connector and the delivery connector, the control system is configured to effect relaxation of the robotic arm to an under-constrained condition, and wherein the control system is configured to effect tensioning of the robotic arm prior to disengagement of the vehicle connector and the delivery connector.

2. The robotic system of claim 1 , wherein the flexible conduit is a hose.

3. The robotic system of claim 1 , wherein the flexible conduit is an electrical cable.

4. The robotic system of claim 1 , wherein the control system includes a sensor for detecting a relative position of the vehicle and the robot arm.

5. The robotic system of claim 1 , wherein the control system includes a sensor for detecting completion of the fueling or charging of the vehicle.

6. The robotic system of claim 1 , wherein the delivery connector is capable of being reconfigured in response to information about the vehicle connector.

7. The robotic system of claim 1 , wherein the delivery connector includes a plurality of delivery connectors of different configurations, and wherein the control system selects a selectable delivery connector of the plurality of delivery connectors which is suitable for use with the vehicle connector.

8. The robotic system of claim 1 , wherein the delivery connector is an electrical delivery connector which includes a plurality of pins or sockets, and the pins or sockets are capable of being configured in response to information about the vehicle connector.

9. The robotic system of claim 1 , wherein the delivery connector is a nozzle, and the nozzle is capable of being configured in response to information about the vehicle connector.

10. The robotic system of claim 1 , wherein the flexible conduit is a hose and the source is one of a plurality of sources containing different liquid fuels.

11. The robotic system of claim 1 , wherein the flexible conduit is a cable and the source delivers different electrical currents.

12. The robotic system of claim 1 , wherein the control system includes a sensor for identifying the vehicle.

13. The robotic system of claim 1 , wherein the control system includes a sensor for detecting a type of fuel present in the vehicle.

14. The robotic system of claim 1 , wherein the control system is configured to effect tensioning of the robotic arm upon completion delivering the fluid or the electrical current.

15. The robotic system of claim 1 , wherein the control system activates the flexible conduit to deliver the fluid to the vehicle to control battery temperature while the flexible conduit delivers the electrical current to the vehicle.

16. The robotic system of claim 1 , wherein the control system directs the robotic arm to engage the delivery connector with the vehicle connector and, upon detecting movement of the vehicle beyond a predetermined threshold, the control system initiates an action to prevent damage to the vehicle or the robotic system.

17. The robotic system of claim 1 , wherein the control system directs the robotic arm to engage the delivery connector with the vehicle connector and, upon detecting a connection failure, the control system initiates an action to prevent a hazard.
