ROBOTIC ARM STRUCTURAL FRAME ENHANCEMENT BY GYROID LATTICE CUBE INTEGRATION

2020 International Journal of Mechatronics and Applied Mechanics  
The article deals with the mechanical behaviour of a robotic arm having a gyroid lattice cell based structural frame within the arm itself. The gyroid is well know for its poriforous structure that can provide remarkable mechanical properties such as stiffness, strength and substantial energy absorption due to the regular and organic structure. Therefore, the gyroid structures are widespread throughout the various industry palette, such as automotive, aerospace, biomedicine and mechanical

The most used technology, especially in mechanical engineering, is the modern additive technology. In this particular case, the gyroid structure is obtained using the selective laser sintering (SLS) additive manufacturing technique. Prior to the manufacturing phase, a designing phase must be conducted starting with a 3D model. Once the final structure has been obtained through 3D designing techniques it is suitable for implementating it within the robotic arm's structural frame. To sum up, in the article have been presented the following: the steps troughout the generative process of the lattice structure, the implementation within the structural frame and manufacturing, including experimental mechanical effort studies.
