Abstract:
1. An attitude control device used to control the attitude of a mounted object, the attitude control device comprising: a first flat-plate member extending in a plane defined by an X-axis and a Y-axis; a second flat-plate member disposed in parallel with the first flat-plate member while being spaced apart from the same, recesses being formed in surfaces of the two flat-plate members facing each other; a spherical member interposed between the first flat-plate member and the second flat-plate member while fitting its portions in the recesses; a first actuator interposed between the first flat-plate member and the second flat-plate member, the first actuator being expandable in a Z-axis direction perpendicular to the plane defined by the X-axis and the Y-axis; and a second actuator connected to the second flat-plate member, the second actuator being expandable in a suitable direction in the plane defined by the X-axis and the Y-axis, wherein the second flat-plate member is movable relative to the first flat-plate member while being in an attitude with an object mounted thereon, and the spherical member is bonded to the first flat-plate member and/or the second flat-plate member by an adhesive elastically deformable.
