Master operation input device and master-slave manipulator
A master operation input device operates a slave manipulator provided with joints adapted to multiple degrees of freedom. The master operation input device includes a grip portion and a first operation portion. The grip portion is variable in position and orientation while being gripped by an operator. The grip portion is configured to give command values regarding the position and orientation of a distal end of the slave manipulator in accordance with the variation in position and orientation. The distal end is the farthest end when the slave manipulator is viewed from a fixed end thereof. The first operation portion is located to be operable by a fingertip of the operator when the grip portion is gripped. The first operation portion is operable independently of the grip portion.

a grip portion which is variable in position and orientation while being gripped by an operator, the grip portion being configured to give command values regarding the position and orientation of a distal end of the slave manipulator in accordance with the variation in position and orientation, the distal end being the farthest end when the slave manipulator is viewed from a fixed end thereof;
a first operation portion to operate at least one of the joints of the slave manipulator, the first operation portion being operable independently of the grip portion; and
a second operation portion to operate an effector provided in the joint at the distal end of the slave manipulator, the second operation portion being attached to the first operation portion, the second operation being operable independently of the first operation portion,
wherein each of the first operation portion and the second operation portion is located to be operable by a fingertip of the operator when the grip portion is gripped.
2. The master operation input device according to claim 1 , wherein the first operation portion has the same structure as a joint at the distal end of the slave manipulator regarding the grip portion, and the first operation portion is configured to give a command value regarding a driving amount to drive the joint at the distal end of the slave manipulator in response to a manual operation.
3. The master operation input device according to claim 1 , wherein the grip portion, the first operation portion, and the second operation portion are collinear.
4. The master operation input device according to claim 1 , wherein the first operation portion is supported by the grip portion.
5. The master operation input device according to claim 4 , wherein the grip portion is attached to an arm portion which is driven in accordance with the variation in position and orientation of the grip portion.
6. The master operation input device according to claim 5 , wherein the first operation portion is further supported by the arm portion.
7. The master operation input device according to claim 1 , wherein the joint at the distal end of the slave manipulator comprises joints adapted to multiple degrees of freedom, and
the first operation portion is configured to give command values regarding driving amounts of the joints provided the joint at the distal end of the slave manipulator.
8. A master-slave manipulator comprising:
a slave manipulator provided with joints adapted to multiple degrees of freedom;
a master operation input device to operate the slave manipulator; and
a control unit configured to calculate a driving amount of each joint of the slave manipulator from the command values regarding the position and orientation and from a command value regarding a driving amount to drive the joint at the distal end of the slave manipulator, the control unit driving each joint of the slave manipulator in accordance with a calculation result of the driving amount,
wherein the master operation input device comprising:
a grip portion which is variable in position and orientation while being gripped by an operator, the grip portion being configured to give command values regarding the position and orientation of a distal end of the slave manipulator in accordance with the variation in position and orientation, the distal end being the farthest end when the slave manipulator is viewed from a fixed end thereof;
a first operation portion to operate at least one of the joints of the slave manipulator, the first operation portion being operable independently of the grip portion; and
a second operation portion to operate an effector provided in the joint at the distal end of the slave manipulator, the second operation portion being attached to the first operation portion, the second operation being operable independently of the first operation portion, and
wherein each of the first operation portion and the second operation portion is located to be operable by a fingertip of the operator when the grip portion is gripped.
9. The master-slave manipulator according to claim 8 , wherein the first operation portion has the same structure as a joint at the distal end of the slave manipulator regarding the grip portion, and the first operation portion is configured to give a command value regarding a driving amount to drive the joint at the distal end of the slave manipulator in response to a manual operation.
10. The master-slave manipulator according to claim 8 , wherein the grip portion, the first operation portion, and the second operation portion are collinear.
11. The master-slave manipulator according to claim 8 , wherein the first operation portion is supported by the grip portion.
12. The master-slave manipulator according to claim 11 , wherein the grip portion is attached to an arm portion which is driven in accordance with the variation in position and orientation of the grip portion.
13. The master-slave manipulator according to claim 12 , wherein the first operation portion is further supported by the arm portion.
14. The master-slave manipulator according to claim 8 , wherein the joint at the distal end of the slave manipulator comprises joints adapted to multiple degrees of freedom, and the first operation portion is configured to give command values regarding driving amounts of the joints provided at the joint at the distal end of the slave manipulator.
