Folding unit based on the plane symmetric Bricard linkage. Folding unit based on the plane symmetric Bricard linkage. (A) Six links are connected to each other by revolute joints. The linkage is separated into two layers: a folding linkage layer and an assembly linkage layer. The folding linkage layer consists of link 1 and link 6. The assembly linkage layer is on top of the folding linkage layer and comprises the remaining four links. (B) As link 6 rotates about link 5, the assembly layer folds link 1 with respect to link 6. (C) By joining a folding unit with its chiral (prime symbol denotes links of the chiral folding unit) by connecting link 1 to link 6′ and link 2 to link 5′, rotation of link 1 about link 6 propagates down the chain.
