Title:
VARIABLE STIFFNESS ACTUATOR
Document Type and Number:
WIPO Patent Application WO/2018/083762
Kind Code:
A1
Abstract:
This variable stiffness actuator (10, 10A) has a shape memory member (20) with a phase which can be changed between a first phase and a second phase. When in the first phase, the shape memory member is in a low stiffness state, and when in the second phase, the shape memory member is in a high stiffness state which is a state of having a stiffness that is higher than that of the low stiffness state. The variable stiffness actuator further has: an inducing member (30) that causes the shape memory member to change its phase between the first phase and the second phase; and a connection member (40, 40A, 40B, 40C, 40D, 40E, 40F, 40G, 40H, 40I, 60) that resiliently connects the shape memory member to the inducing member. The shape memory member, inducing member, and connection member are all conductive, and the shape memory member, inducing member, and connection member are electrically connected.
