Actuator, and robot, brace, and haptic device including the same

Problem

How can vibration in electric motors and rotors be reduced?

Solution

actuator includes: a plurality of wires, one end of each wire of the plurality of wires being engaged with a load; a support member, another end of each wire of the plurality of wires being fixed to the support member; and a drive source configured to rotate the support member, to thereby twist the plurality of wires together, the actuator being configured to change a distance between the support member and the load in accordance with the rotation of the support member.

Key novelty

Each of the plurality of wires is fixed to the support member in a state in which the plurality of wires are twisted in advance in the same twist rotation direction, and when the distance between the support member and the load is reduced, the plurality of wires are rotated in a rotation direction the same as the twist rotation direction and then twisted together.
