Abstract

A system that includes a first self propelled steerable vehicle having a first end and a second end, a second self propelled steerable vehicle having a first end and a second end and an electronic device that maintains a relative position between at least one of the first end and the second end of the first self propelled steerable vehicle and at least one of the first end and the second end of the second self propelled steerable vehicle.

Claims

1. A system, comprising:

a first propelled steerable vehicle having a first end and a second end;

a second propelled steerable vehicle having a first end and a second end; and

an electronic means for maintaining a relative position between at least one of the first end and the second end of the first propelled steerable vehicle and at least one of the first end and the second end of the second propelled steerable vehicle.

2. A system according to claim 1, wherein

the electronic means includes at least one processor in electrical communication with at least one the first propelled steerable vehicle and the second propelled steerable vehicle.

3. A system according to claim 1, wherein

the electronic means includes an infrared sensor.

4. A system according to claim 1, wherein

the electronic means includes a laser.

5. A system according to claim 1, wherein

the electronic means includes visible light.

6. A system according to claim 1, wherein

the first and second propelled steerable vehicles are in electrical communication.

7. A system according to claim 6, wherein

the first and second propelled steerable vehicles are configured to transport a load that can be damaged if subject to two opposite, lateral forces.

8. A system according to claim 7, wherein

the electronic means is configured to maintain the first end of the first propelled steerable vehicle in such a relative position with the second end of the second propelled steerable vehicle that an angle between a line drawn between the first propelled steerable vehicle and the second propelled steerable vehicle and a perpendicular line drawn between the first propelled steerable vehicle and the second propelled steerable vehicle does not exceed about 6 degrees.

9. A method, comprising the steps of

sending signal between at least one of a first end and a second end of a first propelled steerable vehicle and at least one of a first end and a second end of a second propelled steerable vehicle,

determining the relative position of the at least one of the first end and the second end of the first propelled steerable vehicle and the at least one of the first end and the second end of the second propelled steerable vehicle, and

maintaining the relative position to a predetermined range.

10. A method according to claim 9, wherein

the step of maintaining the relative position to a predetermined range includes automatically adjusting the speed of at least one the first propelled steerable vehicle and the second propelled steerable vehicle.

11. A method according to claim 9, wherein

the step of determining the relative position includes using an infrared sensor.

12. A method according to claim 9, wherein

the step of determining the relative position includes using a laser.

13. A method according to claim 9, wherein

the step of determining the relative position includes using visible light.

14. A method according to claim 9, further including the step of

transmitting the relative position to an electrical system that it is electrical communication with both of the first and second propelled steerable vehicles.

15. A method according to claim 9, further including the step of

transporting a load between the first and second propelled steerable vehicles, wherein the load can be damaged if subject to two opposite, lateral forces.

16. A method according to claim 15, wherein

the step of maintaining the relative position includes maintaining the first end of the first propelled steerable vehicle in such a relative position with the second end of the second propelled steerable vehicle that an angle between a line drawn between the first propelled steerable vehicle and the second propelled steerable vehicle and a perpendicular line drawn between the first propelled steerable vehicle and the second propelled steerable vehicle does not exceed about 6 degrees.

17. A vehicle, comprising:

a first propelled steerable vehicle having a first end and a second end and a first electrical system configured to be able to control the velocity of the first propelled steerable vehicle;

a second propelled steerable vehicle having a first end and a second end and a second electrical system configured to be able to control the velocity of the second propelled steerable vehicle; and

a measuring device able to calculate a relative position between at least one of the first end and the second end of the first propelled steerable vehicle and at least one of the first end and the second end of the second propelled steerable vehicle and capable of sending the relative position to at least one of the first and second electrical systems to thereby adjust the velocity of at least one of the first and second propelled steerable vehicle.

18. A vehicle according to claim 17, further comprising

a coupling mechanism configured to couple the first electrical system and the second electrical system and allow electrical communication therebetween.

19. A vehicle according to claim 17, wherein

the first and second propelled steerable vehicles are configured to transport a load that can be damaged if subject to two opposite, lateral forces.

20. A vehicle according to claim 17, wherein

the measuring device is configured to maintain the first end of the first propelled steerable vehicle in such a relative position with the second end of the second propelled steerable vehicle that an angle between a line drawn between the first propelled steerable vehicle and the second propelled steerable vehicle and a perpendicular line drawn between the first propelled steerable vehicle and the second propelled steerable vehicle does not exceed about 6 degrees.
