Abstract:This paper investigates the development of an exact constraint parallel robotic arm unit. In addition to the advantages of simple structure and compact size, the six points exactly constrained parallel robotic arm unit is both statically and kinematicaly deterministic, thus is more suitable for precision position application. Theoretical analysis based on the principle of exact constraint is given to explore the degree of freedom and constrain pattern of the parallel robotic arm unit. Furthermore, the orientat… Show more
