This paper analyzes the mechanical behavior of three materials used in robotic arms: Nylon, PLA, and ABS, with an emphasis on three important parameters: total deformation and equivalent stress in different conditions of loading. In this regard, a finite element analysis was applied via the ANSYS software to simulate structural stiffness as well as their resistance against stress that these materials undergo when strengthened with steel reinforcements. The investigation shows that the performance of Nylon, especially when reinforced with steel, is excellent compared to PLA and ABS in terms of deformability and spread in stress distribution. Therefore, it is more applicable to applications that include higher durability along with minimum deformation when load is applied. The general design and analysis shall indicate some valuable insights in the design of small–scale robotic arms to be used in industries as well as educational institutions.
