A Multi-Threshold-based Force Regulation Policy for Prosthetic Hand Preventing Slippage

Dapeng Yang, Guangxin Wu
2021 IEEE Access  
In this paper, a new slippage prevention strategy is proposed to improve the prosthetic hand's grasp stability.  ...  The slippage occurs between the fingers and object will result in grasp failure that badly affects the prosthetic hand's operation.  ...  Actually, humans may not have quantitative knowledge about gripping force, and the habitual forces using by different individuals are not identical.  ...
