| Abstract: | A kind of humanoid robot paws was developed based on the under-actuated mechanism. Two kinds of gabbing modes (precise nipping and enveloped grabbing) that the paws could a-chieve were analyzed, the relationship between the force acted on object by end joint and inputting torque under precise nipping mode was analyzed by the application of moment equilibrium. Using the virtual work principle to analyze the relationship between forces ac-ted on object by every joint and inputting torque under the envelo-ping grabbing mode, and the grabbing quality of two kinds of grab-bing modes was compared. Finally two modes of grabbing on the cy-lindrical object were simulated in the simulative environment of COSMOSMotion, and the analysis on the grabbing quality was veri-fied. |
