Np. Belfiore, AN ATLAS OF REMOTE ACTUATED BEVEL GEAR WRIST MECHANISMS OF UP TO 9 LINKS, The International journal of robotics research, 12(5), 1993, pp. 448-459
An atlas of topological and functional representations of bevel gear-t
ype basic robotic wrists of up to nine links with all the actuators co
nnected to the frame link is presented. Each wrist mechanism is depict
ed by means of a canonical diagram that can be adopted as a schematic
model for the final constructive embodiment. The corresponding graphic
representation is also shown, together with a reference number that c
lassifies the structure through the concepts of nonfractionated degree
of freedom and equivalent-open-loop chain.
