Humanoid Robotic Hand

A 3D-Printed, cable-driven, single-model, lightweight humanoid robotic hand. ​ The hand is designed with the human body in mind, and the team has tried to replicate as close as possible the intricate movements found in nature. In the robotic hand, there are five bones in the palm, eight bones in the wrist, and 14 bones in the five fingers. The thumb consists of three joints named distal-interphalangeal (DIP) joint, interphalangeal joint, and trapeziometacarpal (TM) joint, whereas the other four fingers comprise three joints named DIP joint, proximal- interphalangeal (PIP) joint, and metacarpophalangeal (MCP) joint
