Abstract

Remote manipulation method and system of the master-slave type in which an operation procedure plan is prepared for defining each of a sequence of pieces of work as being performed by manual operation or automatic operation at least on the basis of information on the level of skill of a human operator and the sequence of pieces of work is performed in accordance with the plan, whereby work can be done efficiently with human operator'"'"'s skill taken into consideration.

Claims

1. A remote manipulation method for performing work including a sequence of operational steps using a manually operable master device and a slave device operable in response to said master device and a programmable control means coupled between said master device and said slave device, comprising the steps of:

producing an operation procedure plan on the basis of data indicating a level of skill of a human operator and data indicating a goal for work to be performed, said plan including a combination of manual operations and automatic operations allocated according to said level of skill of the human operator;

programming said control means in accordance with said plan so that each of said operational steps is defined as being carried out by manual operation of said master by said human operator and/or by automatic operations defined by commanding data produced by said control means; and

actuating said slave by carrying out said manual operations in response to actuation of said master device by said human operator and by carrying out said automatic operations under control of said control means in accordance with said plan.

2. A method according to claim 1, further comprising the steps of updating the data indicating the level of skill of human operator in the course of manual operations of said master device and evaluating said level of skill of said human operator.

3. A method according to claim 2, further comprising the step of updating said operation procedure plan upon said updating of said data indicating the level of skill of the operator.

4. A remote manipulation system having a manually operable master device and a slave device responsive to both manual operation of the master device by a human operator and automatic operation defined by commanding data for performing work including a sequence of operational steps, the system comprising:

planning means for producing an operation procedure plan on the basis of data indicating a level of skill of a human operator and data indicating a goal for work to be performed, said plan including a combination of manual operations and automatic operations allocated according to said level of skill of the human operator and in which each of said operational steps is defined as being carried out by manual operations of said master device or by automatic operations defined by commanding data;

slave managing means coupled to said master device and said planning means for controlling said slave device to carry out said manual operations in response to actuation of said master device by said human operator and automatic operations in said plan; and

interface means coupled between said master device and said slave managing means for providing information on an operational step in said plan to be carried out by manual operation.

5. A system according to claim 4, further comprising memory means for storing said human operator skill level data and said plan.

6. A system according to claim 5, further comprising evaluating means coupled to said memory means for evaluating the skill level of said human operator.

7. A system according to claim 4, in which said interface means includes means for displaying on a display screen an actual image of an object undergoing said work, an actual image of a gripper of said slave device and task items for an operational step to be carried out.

8. A system according to claim 7, in which said interface means further includes means for displaying a position of a goal of the gripper and attendant conditions representative of information for limiting actuation of said slave by said manual operation.

9. A remote manipulation method for performing work including a sequence of operational steps using a manually operable master device and a slave device, comprising the steps of:

preparing an operation procedure plan in which each of said operational steps is defined as being performed by manual operation of the master device or automatic operation defined by operators of commanding data, including determining whether each operational step is to be performed by manual operation or automatic operation at least on the basis of information on the level of skill of a human operator; and

actuating said slave device in accordance with said manual operations and automatic operations in said operational procedure plane for performing said operational steps, whereby work is performed efficiently with the level of skill of a human operator taken into consideration.

10. A method according to claim 9, further comprising the step of updating said operation procedure plan depending upon changes of the level of skill of said human operator in the course of performance of said sequence of operational steps.

11. A remote manipulation system having a manually operable master device and a slave device responsive to both manual operation of the master device by a human operator and automatic operation defined by operators of commanding data for performing work including a sequence of operational steps, the system comprising:

memory means;

means for preparing an operation procedure plan in which each of said operational steps is defined as being performed by manual operation of the master device or automatic operation of commanding data, including means for determining whether each operational step is to be performed by manual operation or automatic operation at least on the basis of information on the level of skill of the human operator, and means for storing said plan in said memory means;

means associated with said memory means and said master device for managing said manual operations;

means associated with said memory means for managing said automatic operations; and

slave control means responsive to the outputs of said manual operation managing means and said automatic operation managing means for actuating said slave device in accordance with said manual operations and automatic operations designated by said operation procedure plan for performing said work.

12. A system according to claim 11, further comprising means associated with said memory means for updating said operation procedure plan depending upon changes of the level of skill of said human operator in the course of performance of said sequence of operational steps.

13. A system according to claim 11, further comprising means for sensing behavior of said slave device and supplying said memory means with information on the current status of said slave device.
