Redefining Robotic Engineering: Harnessing Generative Design, Additive Manufacturing, Printable Conductive Materials, and Wireless Technologies to Develop Novel Articulated Robot Arms

This article demonstrates how four distinct technologies converge to create a new design for articulated robotic arms. Each technology has proven its robustness, processability, and use cases. Generative design is a common approach in mechanical engineering, while additive manufacturing is proven and accepted, even in military applications. Printable conductive materials are used in PCBs and electronics, and wireless technology is indispensable and ubiquitous. A key challenge is that these technologies can interfere with each other. For example, in 3D printing with Fused Filament Fabrication, the curing temperature of conductive ink must be compatible with the plastic's welding temperature. Conductive traces must not interfere with the wireless technology's wavelength to ensure proper function. These factors must be considered in generative design or when using AI in design phases. Despite the challenges, initial tests show promising results. This approach allows for custom-made robotic arms, reduces weight and cabling, and provides flexibility in production processes and materials, paving the way for new robotic applications.
