A key contribution of this work is the creation of a user-friendly interface for recording and simulating hand gestures, allowing for intuitive control and remote operation. The versatility of 3D printing allowed for easy customization and achieved significant cost reductions, making it a more accessible option compared to existing market alternatives, aligned with the economic considerations of the Vietnamese population. Despite limitations such as the absence of an opposable thumb and concerns regarding material durability, the prosthetic arm demonstrated commendable degrees of freedom, succeeded in ultimately enhancing the user experience.
