Parallel manipulators are mechanical devices constituted of two rigid bodies, the base and the platform, connected by other rigid bodies, the legs, which are anchored via joints that allow any rotation around them. The classification of mobile parallel manipulator is an open problem; in particular, mobile manipulators that admit infinitely many legs are still not completely understood. We show that by employing a duality between the space of realizations and the space of possible legs of a manipulator, we can construct a family of mobile mechanisms with infinitely many legs which, to our knowledge, was not present in the literature. This is a joint work with Josef Schicho.
