Abstract
A scissor-bending deployable and foldable metamorphic mechanism unit (SBDFMMU) based on the scissors mechanism is proposed, and the general constraints for constructing SBDFMMUs are given. The mathematical model of the movement of the mechanism unit is established, and degrees of freedom (DOFs) and the movement form of the mechanism is analyzed and calculated. The method of realizing the transformation of the SBDFMMU in the scissors mechanism motion and bending mechanism motion state is proposed. The calculation of the linkage length constraint condition and the angle initial condition required to realize the method are given by calculation and analysis. A method for controlling the bending curvature of the mechanism unit is proposed. The quantitative relationship between the limit linkage length and the bending curvature is obtained by numerical calculation. The mechanism units can be combined in series for the capture of large objects. Three-dimensional models of a single mechanism unit and a combination of two mechanism units are established, and motion simulations are performed to verify the feasibility of the design.
