An index finger of a robot fits in a palm whose function is to perform a certain task or to touch any object for sensing it. The finger is mostly made up of ABS (Acrylonitrile-Butadiene-Styrene) is a low-cost engineering thermoplastic that is easily machined. The assembly consists of the Front piece, Middle piece, Lower piece, Servo Motor, and Motor handle. The main aim of the paper is to evaluate the structural analysis of Index Finger Assembly. Input will be the Index Finger Assembly SOLIDWORKS model and the outputs will be Total deformation, Stress, and Strain plots. The model and analysis are performed using SOLIDWORKS and ANSYS Workbench. Structural analysis is performed on Index Finger Assembly with ABS (Acrylonitrile-Butadiene-Styrene) and Structural Steel material to validate Equivalent stress, Equivalent elastic strain, and Total Deformation.
