Abstract

A method of controlling at least one of a first robot and a second robot to collaborate within a system, the first robot and the second robot being physically separate to one another, the method including: receiving sensed data associated with the second robot; determining position and/or orientation of the second robot using the received sensed data; determining an action for the second robot using the determined position and/or orientation of the second robot; and providing a control signal to the second robot to cause the second robot to perform the determined action to collaborate with the first robot.

Claims

1. A method of controlling at least one of a first robot and a second robot to collaborate within a system, the first robot and the second robot being physically separate to one another, the method comprising:

receiving sensed data associated with the second robot;

determining position and/or orientation of the second robot using the received sensed data;

determining an action for the second robot using the determined position and/or orientation of the second robot; and

providing a control signal to the second robot to cause the second robot to perform the determined action to collaborate with the first robot.

2. A method as claimed in claim 1, wherein the sensed data is associated with a first end of the second robot, the first end comprising one or more devices for performing the determined action.

3. A method as claimed in claim 1, further comprising controlling a three dimensional scanner to obtain the sensed data.

4. A method as claimed in claim 3, wherein the three dimensional scanner is mounted on the first robot.

5. A method as claimed in claim 3, wherein controlling the three dimensional scanner includes:

controlling an emitter to emit electromagnetic waves, the sensed data being received from an electromagnetic wave sensor.

6. A method as claimed in claim 3, wherein controlling the three dimensional scanner includes:

controlling an ultrasonic transducer to emit ultrasonic waves, the sensed data being received from the ultrasonic transducer.

7. A method as claimed in claim 1, further comprising controlling a magnetic transmitter arrangement to provide one or more magnetic fields, the second robot being at least partially positioned within the one or more magnetic fields, the sensed data being received from a magnetic field sensor mounted on the second robot.

8. A method as claimed in claim 1, wherein determining the action for the second robot further comprises using stored data of the structure of the system.

9. A method as claimed in claim 1, wherein the determined action includes movement relative to the system.

10. A method as claimed in claim 1, wherein the determined action includes holding an object within the system to prevent movement of the object within the system.

11. A method as claimed in claim 1, wherein the determined action includes obtaining one or more images of the first robot and/or the system.

12. A method as claimed in claim 1, wherein the determined action includes machining an object within the system.

13. A method as claimed in claim 1, further comprising:

receiving sensed data associated with the first robot;

determining position and/or orientation of the first robot using the received sensed data;

determining an action for the first robot using the determined position and/or orientation of the first robot; and

providing a control signal to the first robot to cause the first robot to perform the determined action to collaborate with the second robot.

14. A non-transitory computer readable storage medium comprising computer readable instructions that, when read by a computer, cause performance of the method as claimed in claim 1.

15. Apparatus for controlling at least one of a first robot and a second robot to collaborate within a system, the first robot and the second robot being physically separate to one another, the apparatus comprising a controller configured to:

receive sensed data associated with the second robot;

determine position and/or orientation of the second robot using the received sensed data;

determine an action for the second robot using the determined position and/or orientation of the second robot; and

provide a control signal to the second robot to cause the second robot to perform the determined action to collaborate with the first robot.

16. Apparatus as claimed in claim 15, wherein the controller is configured to:

receiving sensed data associated with the first robot;

determining position and/or orientation of the first robot using the received sensed data;

determining an action for the first robot using the determined position and/or orientation of the first robot; and

providing a control signal to the first robot to cause the first robot to perform the determined action to collaborate with the second robot.

17. Apparatus as claimed in claim 15, further comprising:

the first robot including a first controller and a first actuator; and

the second robot including a second controller and a second actuator.

18. Apparatus as claimed in claim 17, wherein the first robot is a continuum robot having a first base, the first controller and the first actuator being housed within the first base, and wherein the second robot is a continuum robot having a second base, the second controller and the second actuator being housed within the second base, the first base and the second base being movable relative to one another.

19. Apparatus as claimed in claim 17, wherein the first robot and the second robot each comprise a first end having an interface for interchangeably receiving at least a first device and a second device.

20. Apparatus as claimed in claim 19, wherein the first device includes one or more of:

imaging apparatus;

machining apparatus;

clamping apparatus, and the second device includes one or more of;

imaging apparatus;

machining apparatus;

clamping apparatus.
