This mechanismis  an  evolution  of  the  NaVARo  robot,  a  3-RRR  parallel  robot,  for  which  the  second  revolute  joint  of  the  threelegs is replaced by a scissor to obtain a larger working space and avoid the use of parallelograms to operate thesecond revolute joint.  To obtain better spatial rigidity, the leg mechanism is constructed by placing the scissorsin an orthogonal plane to the plane of the manipulator displacement (3-RRR or even the 3-RPR).
