Abstract:
Example embodiments relate to a link assembly and a leg supporting apparatus using the same. A top end of a frame mounted on a user's thigh can move along a downwardly-concave trajectory. A center of weight of the leg supporting apparatus placed on the top end of the frame converges on a lowest point of the downwardly-concave trajectory so that the user's weight can be stably supported.
Abstract:
A supporting frame and a motion assistance apparatus including the same may be provided. In particular, the supporting frame including a first frame including a hinge connecting portion, a second frame configured to slidingly move with respect to the first frame, and an assistance force sensing portion on at least one of the first frame and the second frame may be provided.
Abstract:
A driving module including a driving source configured to generate power, a rotary rod connected to the driving source to rotate by receiving the power from the driving source, a power conversion block coupled with the rotary rod to be straight-line-driven in a longitudinal direction of the rotary rod in response to a rotation of the rotary rod, and a power transmission unit configured to operate in response to a driving of the power conversion block is disclosed.
Abstract:
A robot arm capable of being driven with a small force while having an enhanced rigidity includes a joint unit formed by stacking a plurality of link modules up against each other, and at least one driving device allowing the joint unit to pivot along at least one axis, wherein the driving device includes a cable disposed to pass through the plurality of link modules a plurality of times, a plurality of multi-turn pulleys configured to change a path of the cable when the cable passes therethrough, such that the cable passes through the plurality of link modules, and a driving unit configured to pull or push the cable such that the joint unit pivots.
Abstract:
A surgical apparatus having sufficient rigidity in a fixed mode and being freely operable in a steering mode includes one or more arm modules having at least one degree of freedom, each arm module including at least one steering cable to steer the arm module and a plurality of link units to form the at least one arm module, each link unit including a head disposed at an upper portion thereof and having a hemispherical shape, a seat formed at a lower portion thereof, and a sliding ball arranged at the seat, wherein the link units are arranged such that the head of one of the link units is seated on the seat of the other of the link units, and the head of one of the link units and the seat of the other of the link units are slid with respect to each other by the sliding ball.
Abstract:
A frame module includes a frame configured to enclose a portion of a user, and at least one reinforcement belt of which both end portions are connected to both sides of the frame, thereby restricting a splaying level of the frame in a predetermined direction.
Abstract:
An exercise assist method includes receiving a user input signal comprising exercise setting information from an external device; measuring, based on the user input signal, a joint angle of a hip joint of a user wearing an exercise assist device configured to assist a user in performing a leg movement; and controlling torque of the exercise assist device to be applied to a leg of the user based on the measured joint angle and the exercise setting information.
Abstract:
A motion assistance apparatus includes a waist frame configured to support a waist of a user, and a proximal support configured to support a proximal part of the user. A pressure applied to a thigh of the user by the proximal support in a sitting state in which the user is sitting may be greater than a pressure applied to the thigh of the user by the proximal support in a standing state in which the user is standing upright.
Abstract:
A driving module including a driving source configured to generate power, a gear train including a decelerating gear set configured to receive driving power from the driving source and a ring gear attached to one side thereof, and a rotary joint including at least one planetary gear configured to rotate using power received from an output end of the decelerating gear set and to revolve along the ring gear is disclosed.
Abstract:
A motion assistance apparatus may include a shank frame configured to support a shank of a user, a thigh frame configured to rotate relative to the shank frame and support a thigh of the user, and a driving frame configured to assist a motion of a hip joint of the user by transmitting power directly or indirectly to the shank frame.
