Contact force optimization for precision grasping of rigid-soft coupled anthropomorphic hand
摘要
Abstract
Aiming at the compliant contacts characteristics of the rigid-soft coupled anthropomorphic hand in precision grasping modes,to make it have the ability of applying grasping force of anthropomorphic hand,the grasping force equilibrium equation and constrained optimization function were first established,and then a finger minimum force optimization method was proposed based on an external penalty function.The anthropomorphic hand could successfully achieve stable grasping of different objects by applying suitable forces,effectively preventing significant deformation or grasping failures during the grasping process.Experimental results show that the measured average values of individual finger forces exhibit absolute errors mostly within the range of 0 to 0.14 N,with relative errors falling between 0 to 18.57%.The proposed approach fulfils the demands of the rigid-soft coupled anthropomorphic hand,enabling stable and reliable grasping of various objects in precision grasping modes.关键词
