Abstract:
A holder may be more easily mounted on a user's body by applying tension to a cable. An inner side surface of the holder with which the user's body comes in contact transmits uniform pressure to the user's body such that the holder may be more comfortable to the user.
Abstract:
According to an aspect of the present invention, it is possible to implement a joint assembly operating similar to a user's actual ankle joint. An ankle joint included in a walking assistant robot is pivotable around a rotation axis located outside the ankle joint.
Abstract:
Disclosed is a manipulator including a wire driving actuator to bend base and terminal sections of a joint assembly in multiple directions by a base section wire and a terminal section wire. The terminal section driving wire is operatively connected to the base section driving wire such that the terminal section driving wire is moved by a distance equal to a movement distance of the base section driving wire. Accordingly, it is possible to prevent bending of the terminal section upon bending the base section.
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.
