Abstract
The purpose of the present work is to design, analyse, manufacture and test semi-circular bellow rubber actuators to function like fingers of an artificial robot hand. The models of the bellow actuators is designed using Solidworks, its’ deflection is analysed using Ansys and tested using the test apparatus designed by us. The effect of parameters are also analysed using Minitab. Bellow actuators made with nitrile and natural rubber are found to sustain up to 6.5 bar and 3.5 bar internal pressure respectively. These bellow actuators exhibit good bending characteristics. A 5-DoF artificial hand, made with nitrile rubber actuators, is found to lift objects weighing up to 220 grams.
