Modification of Anthropomorphic Robotic Hand With Enhanced Strength and Symmetricity

The objective of this research is to model and analysis the design of anthropomorphic robotic hand as per required criteria which manifest enhanced and optimized solutions to common designing problems such as stress distribution, better suitable material, cosmesis and symmetricity characteristics. Current robotic hand designs are openly available. Tolerance issues, printing errors, and poor instructions lead to a significant number of robotics that cannot be assembled, do not work correctly, or break with light use. The aim is to provide a solution to these problems through the use of equation based scaling and proper instructions. After modelling the utility and application of anthropomorphic hand mostly depends upon its efficient and effective mechanism with its cosmesis properties as well. So design must need to analyse cosmesis properties as well which mainly focus upon its decorative and adaptive look. Now a days looks matter a lot because its adaptive nature depends upon human mentality of its perception. As per daily life applications its interactions with local atmospheric constraints is a continuous process which directly impact upon the longevity of material and its performance. Design is done on CATIA V5 R20 and Analysis is done on Ansys 15.0. Finally got Von Misses stress values, principal stress values and displacement values through analysis 5000N payload (assumed on the basis of industrial criteria). The load gives safe values without any failure. Concluded that strength and symmetricity got in a single model.
