Visualization and verification for conceptual design of UNS LPPD hand using CAD/CAE

This paper presents a visualization and verification for conceptual design of UNS LPPD hand based on previous studies. LPPD conducted and focused some researches on providing the low-cost prosthetic hand to respond the need of affordable prosthetic hand in Indonesia. Based on previous research, the new conceptual prototype is designed. The design must consider mechanical criteria by using simple electronic and mechanical properties for control and low energy consumption. This research focused on making the low-friction prosthetic hand design on finger and drive function mechanism. The conceptual prototype was realized into physique prototype and need to be tested for making sure the system is running well. The first step of this research visualizes the concept to detailed design using CAD and prototyping method to bring on the conceptual design of UNS LPPD hand. The end of this research is verifying the design by calculation and testing using engineering analysis techniques.
