Abstract

Compliant kaleidocycles can be widely used in various applications, such as deployable structures, origami structures and metamorphic robots, due to their unique features of continuous rotatability and multistability. Inspired by origami kaleidocycles, a kind of symmetric multistable compliant Bricard mechanism with an arbitrary number of units is presented and analyzed in this paper. First, the basic dimension constraints are developed based on mobility analysis using the screw theory. Second, the kinematic relationships of the actual rotation angle are obtained. Third, a method to determine the number of stabilities and the position of stable states, including the solution for the parameterized boundaries of stable regions, is developed. Finally, experimental platforms are established and the validity of the proposed multistable mechanisms is verified.
