Abstract:
1. A compliant joint comprising: a housing; a rotating member rotatably installed in the housing; and a cam selectively maintaining a connection between the housing and the rotating member or releasing the connection between the housing and the rotating member, wherein: the cam is connected to the rotating member such that the cam is dependent on the rotating member to rotate together with the rotation of the rotating member, or is independent of the rotating member to move in an axial direction of the rotating member separately from the rotating member; the cam is connected to the housing such that the cam can maintain the connection with the housing if an external force applied to the rotating member is below a designated value, and release the connection with the housing if the external force applied to the rotating member is greater than the designated value; elastic members are installed between the cam and the rotating member so as to adhere the cam closely to the rotating member; and the cam includes rollers connected to the housing, and the housing includes cam guide units selectively connected to or separated from the rollers.
