The first control circuit board is electrically coupled to the first motor, and the second control circuit board is electrically coupled to the second motor. The output component of the first speed reducer and the first connecting member are coaxial and arranged along a first direction, and the output component of the second speed reducer and the second connecting member are coaxial and arranged along a second direction that is perpendicular to the first direction. The output shaft of the first motor is connected to the input component of the first speed reducer, and the output shaft of the second motor is connected to the input component of the second speed reducer.

A linkage mechanism includes a chest assembly of a robot; a servo arranged within the chest assembly and comprising an output shaft; a first linkage member including a first end and a second opposite end, the first end being connected to the output shaft; a forearm assembly rotatably connected to the second end of the first linkage member, and a second linkage member. Opposite ends of the second linkage member are rotatably connected to the chest assembly and the forearm assembly.

A laundry apparatus contains a steamer for providing steam, a first unit for blowing the steam towards a fabric and a second unit for blowing a hot gaseous matter towards the fabric, wherein the hot gaseous matter is formed by heating the gaseous matter also with the steam. An apparatus for removing wrinkles from garments contains a hanger for hanging a garment, a steam tube to blow steam into a sleeve of the garment, and an expandable component underneath the shoulder. The expandable component is in a compact state when the sleeve of the garment is initially hung from the shoulder, and in an expanded state to close the passage between the sleeve and a torso of the garment, wherein the steam blocked by the expandable component operates to remove wrinkles in the sleeve.

A bidirectional energy storage device for a joint includes: a sleeve comprising two, opposite open ends; a first sliding member and a second sliding member that are slidably disposed at the open ends of the sleeve, respectively; an elastic member comprising two, opposite ends that are respectively in contact with the first sliding member and the second sliding member; a first telescopic link comprising a first end and an opposite, second end, the first end of the first telescopic link pivotally connected to the first sliding member, the first telescopic link configured to rotate to drive the first sliding member to slide; a second telescopic link comprising a first end and an opposite, second end, the first end of the second telescopic link pivotally connected to the second sliding member, the second telescopic link configured to rotate to drive the second sliding member to slide.

A power transmission device is provided including: a base, provided with a pair of left and right drive pulleys; an intermediate member, rotatably supported by the base about a first axis; and a driven member, rotatably supported by the intermediate member about a second axis. A pair of left wires wound in opposite directions are fixed to the left drive pulley and the driven member. A pair of right wires wound in opposite directions to each other are fixed to the right drive pulley and the driven member. By the drive pulleys, when the driven member is rotated in the same direction about the second axis, torque in opposite directions about the first axis is applied to the driven member, and when the driven member is rotated in opposite directions about the second axis, torque in the same direction about the first axis is applied to the driven member.

A workpiece conveying apparatus for a pressing machine includes: a first arm supported so as to be rotatable within a substantially horizontal plane; a second arm supported on the first arm so as to be rotatable within the substantially horizontal plane; a workpiece holding device supported on a distal end side of the second arm so as to be rotatable within the substantially horizontal plane; a first arm drive mechanism configured to drive the first arm to rotate; a second arm drive mechanism configured to drive the second arm to rotate with respect to the first arm; a workpiece holding device rotation drive mechanism configured to drive the workpiece holding device to rotate with respect to the second arm; and a tilt drive mechanism configured to drive the workpiece holding device to rotate with respect to the second arm.

A manipulator includes a base body, a first link supported to be capable of advancing and retracting with respect to the base body, a first leaf spring connected to a tip of the first link as a rotation pair by a first base end pin, a second link that is arranged with the first link side by side and is supported to be capable of advancing and retracting with respect to the base body, a second leaf spring connected to a tip of the second link as a rotation pair by a second base end pin in the same direction as the first base end pin, and a driven link that is connected to tips of the first and second leaf springs as rotation pairs by first and second tip pins in the same direction as the first and second base end pins, respectively.
