Abstract: Provided is a drive device that can remove the influence of static friction by driving two drive axes with three drive units. A drive device includes: a first drive unit; a second drive unit; a third drive unit; a first differential unit connected to the first drive unit and the second drive unit; a second differential unit connected to the second drive unit and the third drive unit; and a control unit that controls the first to third drive units. The control unit controls the second drive unit at a constant speed, and controls a speed of each of the first drive unit and the third drive unit relative to that of the second drive unit.

Abstract: A support arm device includes a first drive part that is fixed to a base part and cause a first drive shaft to perform shaft rotation, a second drive part that is fixed to the base part and cause a second drive shaft to perform shaft rotation, and an arm part including at least one parallel link and that supports a predetermined tool. The arm part is caused to change an attitude to cause the predetermined tool to perform a predetermined rotational motion by the first drive part and the second drive part being driven.

Abstract: A grip force sensation feedback device including a first rotary member that has an outer peripheral surface including a part of a first virtual conical surface, the first rotary member being rotated around a first cone axis; a second rotary member that has an opposed surface which includes a part of a second virtual conical surface and which is opposed to the outer peripheral surface of the first rotary member, the second rotary member being rotated around a second cone axis; a wire that has both end portions connected to the second rotary member and that has a central portion wound around the first rotary member; and a driving portion that provides a force sensation feedback to a finger of a user in contact with the second rotary member by rotating the first rotary member and thereby causing a rotation of the second rotary member.

Abstract: A parallel link robot includes a movable portion, a base, a plurality of drive sources, a plurality of links, and a tension member. The plurality of drive sources is attached to the base. The plurality of links is respectively connected to the plurality of drive sources. The tension member is connected between the movable portion and at least one of the plurality of links such that a bending tension is generated.

Abstract: An expansion/contraction mechanism includes at least three expansion/contraction members that are formed by coupling respective ends of a plurality of link members sequentially rotatably to each other, and that are capable of performing expansion/contraction operation in predetermined expansion/contraction directions by adjusting an angle between the mutually-coupled link members; and a plurality of connection members that are provided with being aligned along the expansion/contraction directions in a space surrounded by the at least three expansion/contraction members arranged in a state in which the expansion/contraction directions face a substantially same direction, and that are configured to connect the at least three expansion/contraction members to each other. Each of the plurality of connection members pivotally supports the respective link members of the at least three expansion/contraction members that are positioned in a direction orthogonal to the expansion/contraction directions when viewed from itself, so as to be rotatable around itself.
