Abstract: Disclosed is a reconfigurable rotary series elastic element (RSEE) comprising: an inner tension spring mount: an outer tension spring mount; and a plurality of tension springs connected between the inner tension spring mount and outer 5 tension spring mount. A position at which each spring connects to one or both of the inner tension spring mount and outer tension spring mount: can be changed to adjust a relationship between an output torque and deflection angle of the RSEE; and is configured such that, during relative rotation of the inner tension spring mount and outer tension spring mount, an amount of tension in 10 at least one said tension spring differs from an amount of tension in at least one other said tension spring.

Abstract: The present disclosure provides a device for assisting an upper arm of a user, which includes: a support mechanism configured for supporting the device on a torso of the user; an arm link member connectable to the upper arm: a joint member coupled with the arm link member and the support mechanism, and a force generating member arranged on the support mechanism. The device, in use, transfers a load from the upper arm, through the joint member to the torso. The force generating member is configured for providing a resisting torque between the arm link member and support mechanism, and the force generating member is mechanically configured to apply a relatively larger resisting torque at a predetermined range of motion of the upper arm and to apply a relatively lesser resisting torque outside the predetermined range.
