Abstract: A muscular strength assisting apparatus includes a muscular strength assisting portion that assists a user's muscular strength and a first connecting link including one side connected to one side of the muscular strength assisting portion and an opposite side rotatable relative to a shoulder of the user about a first rotation axis. The muscular strength assisting portion includes an upper arm module that assists muscular strength of an upper arm of the user and a link assembly including one side connected to one side of the upper arm module to be rotatable about a second rotation axis non-parallel to the first rotation axis and an opposite side disposed adjacent to a portion of a body of the user to be supported on the user.

Abstract: A strength assist device includes: a multi-link part including one or more links; a profile controller that is connected to one end portion of the multi-link part, and rotates around a central rotational axis; and an elastic force providing part that is connected to the other end portion of the multi-link part, and provides an elastic force to the multi-link part. When the profile controller rotates and one end portion of the multi-link part revolves around the central rotational axis, the elastic force applied to the multi-link part varies.

Abstract: An embodiment power transmission device includes an input shaft rotatable about a first rotation axis, first and second wires wound around an outer surface of the input shaft based on a first radial direction, each having a first side fixed to the input shaft, an output shaft rotatable about a second rotation axis, the output shaft including a shaft body, wherein the first and second wires surround an outer surface of the shaft body based on a second radial direction, and first and second wire holders to which a second side of the first wire and a second side of the second wire are respectively fixed. The first wire extends in a first circumferential direction of the shaft body, and then the first wire extends in a second circumferential direction opposite to the first circumferential direction of the shaft body.

Abstract: The present disclosure relates to a finger-gripper assembly and a finger-gripper assembly system including the same. The finger-gripper assembly includes a finger and a gripper to which the finger is coupled so as to be removable. The gripper includes an arm, an extender coupled to a lower end of the arm so as to be rotatable about a first axis, wherein the extender extends, from the arm along a second axis that extends in an extension direction and intersects with the first axis, and a connector coupled to a lower side of the extender so as to be movable along the second axis, wherein the connector is connectable to the finger.

Abstract: An upper arm module of a wearable muscular strength assisting apparatus is provided. The upper arm module includes a base part configured to be connected to a wearer's body, and an upper arm part having a first end thereof coupled to the base part to be rotatable about a fixed point. The upper arm part is coupled to the wearer's upper arm to apply a torque thereto. The upper arm module further includes an elastic body having a first end thereof fixedly coupled to the upper arm part and generating an elastic force by deformation. In particular, the upper arm module also includes a first link having a first end thereof rotatably coupled to the base part at a point of application, and a second link rotatably coupled to the second end of the first link at a first point.

Abstract: Systems and methods for a perception system for a lower body powered exoskeleton device are provided. The perception system includes a camera configured to capture one or more images of terrain in proximity to the exoskeleton device, an at least one processor. The at least one processor is programmed to perform footstep planning for the exoskeleton device based, at least in part, on the captured one or more images of terrain, and issue an instruction to perform a first action based, at least in part, on the footstep planning.

Abstract: A gripper includes a base unit and finger units coupled to a protruding direction-side of the base unit. Each of the finger units includes a first link structure coupled to the base unit, a second link structure rotatably coupled to the first link structure, and a third link structure rotatably coupled to both the first link structure and the second link structure, and the second link structure includes a finger tip. When the finger unit is pressed in the protrusion direction, the finger tip is brought closer to the base unit in the protrusion direction by the first link structure. When the finger unit is further pressed in the protrusion direction, the finger tip is rotated to be oriented in a direction opposite to the protruding direction in a state in which the finger tip is oriented in a gripping direction that is a direction perpendicular to the protruding direction.
