“…There exist different methods for kinematic synthesis of planar chains with simple joints (Tischler et al, 1995;Belfiore, 2000;Rao & Deshmukh, 2001): intuition and inspection (Crossley, 1964), graphs theory (Dobrjanskyi and Freudenstein, 1967;Woo, 1967). Others consist in transformation of binary chains (Mruthyunjaya, 1979;Mruthyunjaya, 1984-a;Mruthyunjaya, 1984-b;Mruthyunjaya, 1984-c), in the concept of Assur groups Manolescu, 1964;Manolescu, 1979;Manolescu, 1987), or Franke's notation (Davies & Crossley, 1966;Crossley, 1966). Recently, new methods based on genetic algorithms or neuronal networks are also used (Tejomurtula & Kak, 1999;Abo-Hamour et al, 2002;Cabrera et al, 2002;Laribi et al, 2004).…”
