Abstract

A robotic vehicle capable of collapsing into a small form factor for ease of transportation and providing for a quick transition to a deployed configuration. The vehicle can be configured to carry a payload when deployed. The vehicle can have an elongate body with two folding spoke-wheels at either end of the body that conform to the shape of the body when collapsed and extend perpendicular to the body when deployed. The vehicle can have an elongate body with two folding arms that each includes a drive motor and a gear assembly. The gear assembly is configured to receive removable wheels at either end of the body. The arms can be parallel to the length of the body when collapsed and extend perpendicular to the body when deployed. The vehicle can include a removable bracket configured to receive an explosive payload.

Claims

1. A robotic vehicle comprising:

a body defining an interior compartment and an exterior surface, the body including two ends;

a pair of motors disposed within the interior compartment;

an electronics package disposed within the interior compartment electronically coupled to each one of the pair of motors, the electronics package being coupled to a video camera and at least one transmitter configured to transmit images from the video camera;

a collapsible wheel assembly coupled to each end of the body, the wheel assembly including a hub, a plurality of spokes coupled to the hub at a pivot, and a removable end cap physically mated to the hub, the hub being operably coupled to one of the pair of motors; and

a payload removably coupled to the exterior surface of the body;

wherein the removable end cap maintains the plurality of spokes in a first deployed configuration when mated to the hub.

2. The robotic vehicle of claim 1, wherein the payload is coupled to the exterior surface of the body by a bracket that surrounds a portion of the body and suspends the payload below the body.

3. The robotic vehicle of claim 1, wherein the payload is coupled to the exterior surface of the body by a bracket that surrounds a portion of the body and suspends the payload in front of the body.

4. The robotic vehicle of claim 1, wherein the plurality of spokes each include a curved foot at an end opposite an end where each spoke is coupled to the hub.

5. The robotic vehicle of claim 1, wherein the removable end cap includes a locking mechanism that secures the end cap to the hub;

and

wherein the removal of the end cap allows the plurality of spokes to transition from a stowed configuration to a deployed configuration by rotation about the pivot, the end cap retaining the plurality of spokes in the stowed configuration or the deployed configuration when physically mated to the hub.

6. A robot device comprising:

a body defining an interior compartment and an exterior surface;

a pair of arms coupled to the exterior surface the body by a pivot, each one of the pair of arms including a spring-loaded locking pin configured to mate with a first port in the body when the arms are in a deployed position, and a second port in the body when the arms are in a stowed position, wherein each of the pair of arms can rotate between zero and ninety degrees between the deployed position and the stowed position;

a motor disposed on each one of the pair of arms;

a gear assembly coupled to the motor on each one of the pair of arms;

a removable wheel assembly operably coupled to each gear assembly;

a detachable tail assembly; and

a payload coupled to the body.

7. The robot device of claim 6, wherein each one of the pair of arms can rotate on the pivot independently of the other arm.

8. The robot device of claim 6, wherein the payload is coupled to the body with a removable bracket.

9. The robot device of claim 6, wherein the payload is coupled to an exterior surface on the underside of the body.

10. The robot device of claim 6, wherein the robot device can be completely contained in a container having a volume of between 45 and 55 cubic inches when in the stowed position.

11. The robotic device of claim 6, further comprising a tail coupled to the body and configured to act as a counterweight to offset the angular rotation of the pair of wheels.

12. A robotic vehicle comprising:

a body defining an interior compartment and an exterior surface, the body including two ends;

a pair of motors disposed within the interior compartment;

an electronics package disposed within the interior compartment electronically coupled to each one of the pair of motors;

a pair of wheels, each wheel being removably coupled to one of the pair of motors at each end of the body;

a pair of mounting brackets configured to surround a portion of the body at each end, and including an attachment point;

a payload coupled to the attachment point of the bracket.

13. The robot vehicle of claim 12, wherein the robot vehicle can be completely contained in a container having a volume between 250 and 350 cubic inches.

14. The robot vehicle of claim 12, wherein the robot vehicle can be completely contained in a container having a volume between 45 and 55 cubic inches.

15. The robotic vehicle of claim 12, wherein the payload is coupled to the exterior surface of the body by the mounting brackets such the payload is below the body.

16. The robotic vehicle of claim 12, wherein the payload is coupled to the exterior surface of the body by the mounting brackets such the payload is in front of the body.

17. The robotic vehicle of claim 12, further comprising a tail coupled to the body and configured to act as a counterweight to offset the angular rotation of the pair of wheels.

18. The robotic vehicle of claim 17, wherein the tail coupled to the body comprises a pair of removable counterweights that have a mass proportional to the mass of the payload.

19. A controller for a robotic vehicle comprising:

a joystick having a 360-degree range of horizontal motion and including a switch that is activated when the joystick is depressed vertically;

a pair of transmitters and receivers configured to communicate with the robotic vehicle;

a video display screen having a backlight that can be adjusted to vary a brightness level of the video display screen, the video display screen being configured to receive a video signal input from at least one of the pair of receivers; and

a processor coupled to the backlight, the joystick, and the pair of transmitters and receivers, the processor being configured to interpret operator actuation of the joystick and direct the robotic vehicle in response to the actuation of the joystick by transmitting commands via the pair of transmitters;

wherein the processor is further configured to adjust the brightness level of the video display screen by varying the intensity of the backlight in response to the combined actuation of the joystick and the switch.

20. The controller of claim 19, where in the video display screen is a liquid crystal display (LCD) screen.
