Abstract

It is proposed that a real or virtual slave system with p degrees of freedom is controlled by means of a manual control member comprising a handle (10) formed by an active part (12) and one or two information return parts (14). A speed or displacement transducer or sensor (24) can be mounted in the active part (12) in order to produce signals used for controlling the slave system. Actuators, e.g. fitted in a support connected to the handle (10) by a flexible cord (22), receive informations from the slave system and transform them into a torque. This torque is transmitted to the information return part (14), e.g. by cables (30,34), so that a stress or force representative of the information from the slave system is applied to the hand of the operator.

Claims

a handle having an outer surface mainly formed of an active part and of at least one information return part, the information return part being separate from and movable with respect to the active part and having at least two degrees of freedom;

means for controlling movements of the slave system in response to an action on the active part of the handle; and

means for controlling movements of each information return part with respect to the active part, in response to information return signals from the slave system.

15. A manual control member according to any of claims 1 to 14, wherein the information return part includes at least one button for controlling the coupling of the control member to the slave system.

16. A manual control member according to any of claims 1 to 14, wherein the handle includes at least one display.

2. A manual control member of a slave system, wherein the member comprises;

a handle having an outer surface mainly formed of an active part and of a single information return part forming an end portion of the handle, the information return part being separate from and movable with respect to the active part and has at least two degrees of freedom;

means for controlling movements of the slave system in response to an action on the active part of the handle; and

means for controlling movements of each information return part with respect to the active part, in response to information return signals from the slave system.

3. A manual control member of a slave system, wherein the member comprises:

a handle having an outer surface mainly formed of an active part forming two end portions of the handle, and of a single information return part, the information return part forming a central portion of the handle, intercalated between the end portions, the information return part being separate from and movable with respect to the active part and having at least two degrees of freedom;

means for controlling movements of the slave system in response to an action on the active part of the handle; and

means for controlling movements of each information return part with respect to the active part, in response to information return signals from the slave system.

4. A manual control member of a slave system, wherein the member comprises:

a handle having an outer surface mainly formed of an active part perforated by openings, and of at least one information return part having protuberances located in the openings, the information return part being separate from and movable with respect to the active part and having at least two degrees of freedom;

means for controlling movements of the slave system in response to an action on the active part of the handle; and

means for controlling movements of each information return part with respect to the active part, in response to information return signals from the slave system.

5. A manual control member of a slave system, wherein the member comprises:

a handle having an outer surface mainly formed of an active part and of two information return parts, the information return parts being separate from and independently movable with respect to the active part and having at least two degrees of freedom;

means for controlling movements of the slave system in response to an action on the active part of the handle; and

means for controlling movements of each information return part with respect to the active part, in response to information return signals from the slave system.

6. The manual control member according to claim 5, wherein the information return parts are arranged symmetrically with respect to a median plane of the handle and form an end portion of the handle.

7. A manual control member of a slave system, wherein the member comprises:

a handle having an outer surface formed of an active part, of at least one information return part, the information return part being separate from and movable with respect to the active part and having at least two degrees of freedom, and of at least one flexible member ensuring a continuity of the outer surface between the active and information return parts;

means for controlling movements of the slave system in response to an action on the active part of the handle; and

means for controlling movements of each information return part with respect to the active part, in response to information return signals from the slave system.

8. A manual control member of a slave system, having p degrees of freedom, wherein the member comprises:

a handle having an outer surface mainly formed of an active part and of q information return parts separate from and movable with respect to the active part, each information return part having r degrees of freedom with respect to the active part, with r>

2.

means for controlling movements of the slave system in response to an action on the active part of the handle;

a support independent of the movement control means of the slave system; and

means for controlling movements of each information return part with respect to the active part, in response to information return signal from the slave system, the movement control means of each information return part including at least one actuator mounted in the support and movement transmission means connecting the actuator to the information return part.

9. The manual control member according to claim 8, wherein the active part of the handle is connected to the support by a flexible cord through which the movement transmission means extends.

10. The manual control member according to claim 8, wherein the active part of the handle is mechanically connected to the support by an articulated arm through which the movement transmission means extends.

11. The manual control member according to claim 8, wherein the movement transmission means includes at least two cables slidably disposed in sheaths, a first of the cables connecting a first actuator to each information return part through a movement inversion means and a second of the cables directly connecting a second actuator to each information return part.

12. The manual control member according to claim 11, comprising p second actuators.

13. A manual control member of a slave system, wherein the member comprises:

a handle having an outer surface mainly formed of an active part and of at least one information return part, the information return part being separate from and movable with respect to the active part and having at least two degrees of freedom;

means for controlling movements of the slave system in response to an action on the active part of the handle; and

means for controlling movements of each information return part with respect to the active part, in response to information return signals from the slave system, the movement control means of the information return part comprising at least one actuator mounted in the handle.
