Abstract
A parallel link mechanism is configured so that a plurality of linear actuators which are supported on a base are used to linearly shift one end part of each of links so as to move an end effector coupled to the other end parts of the links. The manipulator further includes a rotation support part that is provided between the end effector and the parallel link mechanism and that supports the end effector rotatably around a predetermined rotational axis, and a hydraulic drive mechanism that generates in the end effector rotating power around the rotational axis. The manipulator imparts, from the exterior to the hydraulic drive mechanism, change in the working-fluid hydraulic pressure so as to generate movement for rotating the end effector.
Claims4
A manipulator for microscopic work that executes a predetermined operation related to microscopic work on a work object instead of a person, the manipulator for microscopic work comprising:
- a tip operation part that is configured to execute a handling operation of the work object or an instrument for work;
- a link mechanism that is configured to be capable of changing a position and an orientation of the tip operation part in a space in which the work object is present;
- and
- a support part that is between the link mechanism and the tip operation part and is configured to support the tip operation part on the link mechanism, wherein
- the support part includes a first drive mechanism that is configured to drive the tip operation part to generate the handling operation and a second drive mechanism that is configured to rotate the tip operation part around a predetermined rotational axis, and not only the second drive mechanism but also the link mechanism is configured to be capable of rotating the tip operation part around predetermined rotational axis, wherein
- the rotation of the tip operation part is performed in a first angle range by using the link mechanism,
- the rotation of the tip operation part by using the second drive mechanism is performed in a second angle range,
- a size of the first angle range is different from a size of the second angle range, and
- the first angle range is smaller than the second angle range.
