Abstract :
This paper presents a systematic methodology to
convert planar 3 degree-of-freedom open 4-bar chain
into planar 1 degree-of-freedom 6-bar linkages. This
objective is achieved by adding 2RR chains to the
original mechanism. Hence, these additional chains
mechanically constrain the relative movement of the
end-effector to reach a required set of task positions.
Graphical enumeration technique is applied for
structural synthesis of all possible 6-bar linkages.
Structural code technique is introduced as a new
method for structural isomorphism. The proposed
methodology produces 7 different forms of 6-bar
linkages.
