About

N. M. P. Arachchige is a robotics researcher specializing in assistive and rehabilitation technologies, with a particular focus on upper-limb prosthetics and human-robot interaction. Their most notable contribution is the development of MoBio, a 5-degree-of-freedom (DOF) trans-humeral robotic prosthesis introduced in a 2017 paper that has garnered 22 citations. This work addresses a critical gap in prosthetic design by incorporating two DOF at the wrist—wrist radial/ulnar deviation—along with elbow flexion/extension and forearm supination/pronation, enabling more natural and functional movements. By leveraging anthropometric features, Arachchige’s design enhances the prosthesis’s ability to mimic human arm kinematics, improving user comfort and dexterity. This innovation stands out in a field where most trans-humeral prostheses offer limited wrist mobility. Arachchige’s research has implications for improving the quality of life for individuals with upper-limb amputations, and their work continues to influence the development of more intuitive and adaptive prosthetic systems. Their contributions underscore a commitment to bridging engineering and clinical needs, making them a key figure in advancing robotic prosthetics.
