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 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:
Driving modules, motion assistance apparatuses including at least one of the driving modules, and methods of controlling at least one of the motion assistance apparatus may be provided. For example, a driving module including a driving source on one side of a user and configured to transmit power, an input side rotary body connected to the driving source and configured to rotate, and a first decelerator and a second decelerator configured to operate using the power received from the driving source through the input side rotary body, wherein a gear ratio from the input side rotary body to an output terminal of the first decelerator differs from a gear ratio from the input side rotary body to an output terminal of the second decelerator, may be provided.
Abstract:
In a joint assembly of a walking assistance robot that is capable of performing an operation with 3 degrees of freedom, similarly to a user's joint, a rolling motion and a sliding motion are simultaneously made, and a rotation center changes so that the joint assembly can make a similar motion to that of an actual knee joint of the user. Thus, when the user wears the walking assistance robot and walks, misalignment can be prevented from occurring in the knee joint.
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.
