A device includes a tube and a sleeve configured to at least partially encircle a portion the tube along its length. The tube is flexible and airtight and defines a longitudinal axis along a center of the tube, and is configured to bend along the longitudinal axis upon at least partial evacuation of the tube to form a joint. The joint defines a joint angle relative to the longitudinal axis, thereby approximating a revolute joint with torsional stiffness. Actuating a joint includes partially evacuating a flexible tube defining a longitudinal axis, thereby forming a bend in the tube at an angle with respect to the longitudinal axis at a perimeter of a rigid sleeve at least partially encircling the tube, and restoring a neutral pressure to the tube, thereby removing the bend in the tube.
