The chapter presents a family of new deployable mechanisms obtained by conjoining an indefinite number of copies and variants of the same basic spatial linkage. The unit mechanism is an assembly of scissor and Sarrus linkages able to move in two or three independent directions. Unlike most deployable structures, which have one degree of freedom, the proposed devices can be deployed and compacted independently in two or three directions. Moreover, the physical boundary of the mechanism can be used to approximate and control the shape of some geometric curves. Kinematic simulations are performed to validate the proposed designs.

Abstract
The chapter presents a family of new deployable mechanisms obtained by conjoining an indefinite number of copies and variants of the same basic spatial linkage. The unit mechanism is an assembly of scissor and Sarrus linkages able to move in two or three independent directions. Unlike most deployable structures, which have one degree of freedom, the proposed devices can be deployed and compacted independently in two or three directions. Moreover, the physical boundary of the mechanism can be used to approximate and control the shape of some geometric curves. Kinematic simulations are performed to validate the proposed designs.
