A　suitable　comprehensive　evaluation　method　for　similarity　comprehensive　evaluation　of　humanoid　motion　(mainly　to　robotic　arm)　is　proposed.　For　different　robotic　arms,　a　static　comprehensive　evaluation　model　is　established　by　projection　pursuit　evaluation　based　on　indexes　of　humanoid　robot　arm　motion　in　robotics　and　ergonomics　field.　Based　on　projection　pursuit　evaluation　with　timing　information　entropy　and　time　degrees,　a　dynamic　comprehensive　evaluation　method　is　proposed　by　linear　weighting　to　each　time＇s　static　model＇s　indexes　weight　according　to　timing　weighted　vectors.　Through　comparing　similarity　comprehensive　evaluation　result　based　on　static　and　dynamic　comprehensive　evaluation　model,　the　results　show　that　similarity　based　on　dynamic　comprehensive　evaluation　model　is　high.　By　comparing　reliability,　similarity　and　dispersion　of　static　and　dynamic　comprehensive　evaluation　models,　the　results　show　that　dynamic　comprehensive　evaluation　result　has　better　accuracy,　stability　and　lower　dispersion,　and　the　result　is　more　reasonable　and　real.　Therefore,　the　dynamic　comprehensive　evaluation　method　proposed　in　this　paper　is　more　suitable　for　similarity　comprehensive　evaluation　of　humanoid　robot　arm　motion.　Copyright　©　by　HIGH　TECHNOLOGY　LETTERS　PRESS.
