The major areas covered by this thesis arc the synthesis and analysis of the RRSS spatial mechanism. The RRSS mechanism is a four-link mechanism composed of two revolute (R) joints and two spheric (S) joints. The notation RRSS indicates the order of connection of the joints. A computer program in FORTRAN 77 has been written for three to seven positions synthesis, as well as analyses of the RRSS mechanism. Linear equations are involved in the synthesis of R-R dyad for three and four positions. For five to seven positions, non-linear equations arc involved and the R-R dyads arc synthesized using a least-squares algorithm. For S-S dyad synthesis, all equations arc non-linear. The analysis section of this thesis includes both kinematics and input-link rotatability analyses. A synthesized RRSS mechanism has been included as an example.
