Abstract

In a master-slave manipulator system, manipulation device can be manipulated intuitively even when clutch manipulation is performed. A master-slave manipulator system includes: mode switching device for switching between a master-slave mode, in which the slave manipulator is controlled, and an observation device visual field tracking clutch mode, in which transmission of an operation command to the slave manipulator from the manipulation device is cut off to move the manipulation device to an optional position and orientation; a switching unit control section that reads a signal of the mode switching device to forward a mode signal to the manipulation device control section; and a visual field transform section that forwards a third control command to the manipulator control section and forwards a fourth control command to the visual field change control section on the basis of an operation command read by the manipulation device control section at the time of the observation device visual field tracking clutch mode so as to make an agreement between a direction of motion of an image of the slave manipulator displayed on the display device and a direction of manipulation of the manipulation device.

Claims (39)

1. A master-slave manipulator system comprising:

manipulation means that is manipulated in order to create an operation command;

a manipulation means control section that reads the operation command to forward a first control command;

a manipulator control section, by which a second control command for controlling of respective joints of a slave manipulator is output on the basis of the first control command;

the slave manipulator that operates on the basis of the second control command;

observation means that observes a motion of the slave manipulator;

visual field changing means that changes a visual field of the observation means;

a visual field change control section that controls the visual field changing means;

display means that displays an image of the manipulator observed by the observation means on a screen;

mode switching means for switching between a master-slave mode, in which the slave manipulator is controlled, and an observation means visual field tracking clutch mode, in which transmission of an operation command to the slave manipulator from the manipulation means is cut off to move the manipulation means to an optional position and orientation;

a switching unit control section that reads a signal of the mode switching means to forward a mode signal to the manipulation means control section; and

a visual field transform section that forwards a third control command to the manipulator control section and forwards a fourth control command to the visual field change control section on the basis of an operation command read by the manipulation means control section at the time of the observation means visual field tracking clutch mode so as to make an agreement between a direction of motion of an image of the slave manipulator displayed on the display means and a direction of manipulation of the manipulation means.

2. A master-slave manipulator system comprising:

manipulation means that is manipulated in order to create an operation command;

a manipulation means control section that reads the operation command to forward a first control command;

a manipulator control section, by which a second control command for controlling of respective joints of a slave manipulator is output on the basis of the first control command;

the slave manipulator that operates on the basis of the second control command;

observation means that observes a motion of the slave manipulator;

visual field changing means that changes a visual field of the observation means;

a visual field change control section that controls the visual field changing means;

display means that displays an image of the manipulator observed by the observation means on a screen;

mode switching means for switching between a master-slave mode, in which an object operated by the manipulation means comprises the slave manipulator and the observation means, and an observation means visual field tracking master-slave mode, in which an object operated by the manipulation means comprises an observation means visual field;

a switching unit control section that reads a signal of the mode switching means to forward a mode signal to the manipulation means control section; and

a visual field transform section that forwards a third control command to the manipulator control section and forwards a fourth control command to the visual field change control section on the basis of an operation command at the time of the observation means visual field tracking master-slave mode so as to make an agreement between a direction of motion of an image of the slave manipulator displayed on the display means and a direction of manipulation of the manipulation means.

3. A master-slave manipulator system comprising:

manipulation means that is manipulated in order to create an operation command;

a manipulation means control section that reads the operation command to forward a first control command;

a manipulator control section, by which a second control command for controlling of respective joints of a slave manipulator is output on the basis of the first control command;

the slave manipulator that operates on the basis of the second control command;

observation means that observes a motion of the slave manipulator;

visual field changing means that changes a visual field of the observation means;

a visual field change control section that controls the visual field changing means;

display means that displays an image of the manipulator observed by the observation means on a screen;

mode switching means for switching among a master-slave mode, in which the slave manipulator is controlled, an observation means visual field tracking clutch mode, in which transmission of an operation command to the slave manipulator from the manipulation means is cut off to move the manipulation means to an optional position and orientation, and an observation means visual field tracking master-slave mode, in which an object operated by the manipulation means comprises the slave manipulator and an observation means visual field;

a switching unit control section that reads a signal of the mode switching means to forward a mode signal to the manipulation means control section; and

a visual field transform section that forwards a third control command to the manipulator control section and forwards a fourth control command to the visual field change control section on the basis of an operation command read by the manipulation means control section at the time of the observation means visual field tracking clutch mode so as to make an agreement between a direction of motion of an image of the slave manipulator displayed on the display means and a direction of manipulation of the manipulation means.

4. The master-slave manipulator system according to claim 1 , wherein double-arm manipulation means is used as the manipulation means, and two or more manipulators are used as the slave manipulator, and in the observation means visual field tracking clutch mode, zooming-out and zooming-in of a visual field by the observation means are realized in accordance with positive and negative of a differential of a distance between position command input portions of the double-arm manipulation means.

5. The master-slave manipulator system according to claim 2 , wherein double-arm manipulation means is used as the manipulation means, and two or more manipulators are used as the slave manipulator, and in the observation means visual field tracking clutch mode, zooming-out and zooming-in of a visual field by the observation means are realized in accordance with positive and negative of a differential of a distance between position command input portions of the double-arm manipulation means.

6. The master-slave manipulator system according to claim 3 , wherein double-arm manipulation means is used as the manipulation means, and two or more manipulators are used as the slave manipulator, and in the observation means visual field tracking clutch mode, zooming-out and zooming-in of a visual field by the observation means are realized in accordance with positive and negative of a differential of a distance between position command input portions of the double-arm manipulation means.
