PARALLEL MECHANISM
First Claim
1. A parallel mechanism comprising:
- a fixed plate comprising four directions;
four turnable actuators each comprising a rotor and disposed in the respective four directions of the fixed plate with pivot axes of two adjacent turnable actuators among the four turnable actuators being orthogonal to one another and with pivot axes of two opposing turnable actuators among the four turnable actuators being parallel to one another;
four peripheral driving mechanisms each comprising;
an upper arm comprising a bar integral with the rotor of a turnable actuator among the four turnable actuators corresponding to the upper arm;
a lower arm;
an upper joint coupling the upper arm and the lower arm to one another; and
a lower joint coupling the lower arm and a movable plate to one another;
andthe movable plate comprising a plane direction and being driven by the four turnable actuators through the four peripheral driving mechanisms with at least four degrees of freedom comprising one rotational degree of freedom along the plane direction of the movable plate.

Abstract
A parallel mechanism includes a fixed plate, four turnable actuators, four peripheral driving mechanisms, and a movable plate. The four turnable actuators are disposed in respective four directions of the fixed plate with pivot axes of two adjacent turnable actuators being orthogonal to one another and with pivot axes of two opposing turnable actuators being parallel to one another. The four peripheral driving mechanisms each include an upper arm made up of a bar integral with a rotor of a turnable actuator corresponding to the upper arm. An upper joint couples the upper arm to the lower arm. A lower joint couples the lower arm to the movable plate. The movable plate is driven by the four turnable actuators through the four peripheral driving mechanisms with at least four degrees of freedom including one rotational degree of freedom along a plane direction of the movable plate.
