| Abstract: | This paper proposed a new type fingertip force sensor which can be applied in Robot finger. The sensor can detect loading information in three directions and export corresponding signal for control system of robot,in order to control or adjust the force of fingertip and implement a series of behaviors, for example,picking and putting objects.The sensor materials were selected.Structural models and measuring bridge were designed.Finite element method was applied in numerical simulation.The spatial distribution of stress at measured points was obtained.The computational results show that double-hole fingertip force sensor can measure load in three directions accurately in the case of complex stress. |
