“…As for a parallel mechanism, methods of reducing the measurement cost were reported (Tanaka et al, 2005;Imoto et al, 2008;Daney et al, 2005). As one of the methods of selecting optimal measurement poses, the possibility of using genetic algorithm (GA) was introduced (Daney et al, 2005): however, it was still on the idea stage, i.e., it was not experimentally applied to a practical parallel mechanism.…”
