Abstract: Provided is a motion assistance apparatus that includes a fixing module which is fixed to a part of the body of a user, a support module which supports another part of the body of the user and is rotatable relative to the fixing module, a first driving module which is positioned between the fixing module and the support module and abducts the support module relative to the fixing module, and a second driving module which flexes the support module relative to the fixing module. The first driving module includes an abduction motor, and a first axis serving as an abduction axis of the first driving module is positioned at the same height as or lower than a second axis serving as a flexion axis of the second driving module.

Abstract: Provided is a robot pressing mechanism which includes a pressing device extending in a first direction, a support device connected to the pressing device and moving in the first direction relative to the pressing device, and a flat spring configured to connect the pressing device to the support device. The support device includes a guide member spaced apart from the pressing device in a direction crossing the first direction. The flat spring includes a first plate coupled to the pressing device and extending in the first direction, a second plate coupled to the guide member and extending in a direction in which the guide member extends, and a third plate bent to connect one end of the first plate to one end of the second plate.
