.... Overconstrained mechanisms often require mathematically perfect geometries. When analyzed assuming perfect geometry, redundant constraints are observed and motion is allowed. However, without perfect geometry, the previously redundant constraints become conflicting constraints and render the linkage immobile...

First, a new topological scheme and a new rectangular prism deployable linkage unit are proposed...

... and assign rotation axes to assemble the portions into movable blocks. Interestingly, this connects the Bricard classical linkages developed in 1897 to these ori-blocks with coincidence of the position and orientation of the axes when the blocks are replaced by links. The study bridges the gap between ori...
