A link actuation device includes a proximal-end-side link hub, a distal-end-side link hub, three or more link mechanisms each coupling the link hubs such that a posture of the distal-end-side link hub can be changed relative to the proximal-end-side link hub. Each link mechanism includes a proximal-side end link member, a proximal-side intermediate link member, a distal-side intermediate link member, and a distal-side end link member. Actuators for arbitrarily changing the posture and a distance from the distal-end-side link hub to the proximal-end-side link hub are provided to three or more link mechanisms of the three or more link mechanisms. A control unit calculates a rotation angle of the proximal-side end link member according to a targeted posture of the distal-end-side link hub and a targeted distance between the centers of the spherical links, and controls the respective actuators so as to attain the calculated rotation angle.

An actuator system includes a frame configured to remain stationary relative to a carriage within the frame and connected to the frame by a flexure assembly configured to constrain the carriage for only linear motion along an axis of the actuator system. A rotary base is configured to receive rotational input. Cross-blade flexures operatively connect the carriage to the rotary base, the cross-blade flexures including a plurality of blade flexures and being oriented at an oblique angle to the rotary base and to the axis of the actuator system. A rotary flexure operatively connects the rotary base to the frame. The cross-blade flexures and the rotary flexure are configured to convert rotary motion of the rotary base into linear motion of the carriage and to maintain axial and lateral stiffness.

A vehicle mechanism with a housing may have a spindle/nut assembly and a rotation lock, where in order to displace a spindle rod of the spindle/nut assembly in the longitudinal direction of the spindle rod, a rotational movement of a spindle nut of the spindle/nut assembly is blocked by the rotation lock. In order to support the spindle nut such that it cannot rotate, and/or to facilitate an assembly of the vehicle mechanism, and/or the rotation lock, the rotation lock may have at least one elastomer element for retaining the rotation lock on the housing.

A barricade includes a foundation frame, a finger wedge barrier, a hinge hingedly coupling the finger wedge barrier to the foundation frame, and an actuator mechanism coupled to the foundation frame and the finger wedge barrier. The finger wedge barrier is configured to rotate about the hinge between a stowed configuration and a deployed configuration, and the actuator mechanism is configured to rotate the finger wedge barrier between the stowed configuration and the deployed configuration. The actuator mechanism includes an actuator comprising a housing and a rod configured to reciprocally move in the housing, a first linkage having a first end rotatably coupled to the rod and a second end rotatably coupled to the finger wedge barrier, and a second linkage having a first end rotatably coupled to the rod and a second end rotatably coupled to the foundation frame.

A mower-conditioner includes first and second conditioning rolls, adjustment assembly, and a linkage. The adjustment assembly includes a first member having a first helical surface and a second member having a second helical surface in contact with each other. The linkage is coupled between the at least one adjustment assembly and the first conditioning roll. The rotation of the at least one adjustment assembly about a pivot axis causes the first conditioning roll to move via the linkage, which adjusts the distance between the first and second conditioning rolls.

A control arm assembly for controlling a robot system includes a gimbal that is moveable and rotatable about three axes, and a handle assembly coupled to the gimbal. The handle assembly includes a body portion having a controller disposed therein and a first actuator disposed thereon. The first actuator is mechanically coupled to the controller via a four-bar linkage such that actuation of the first actuator causes mechanical movement of a component of the controller which is converted by the controller into an electrical signal.
