About

N. G. Tsagarakis is a leading figure in humanoid robotics and rehabilitation technology, with research spanning compliant locomotion, dexterous manipulation, and medical robotics. He is best known for his pioneering work on the design and control of humanoid platforms, including the iCub robot, for which he developed a low-cost, under-actuated hand that advanced the field of affordable robotic manipulation. His contributions to bipedal walking are equally significant; his 2011 study on energy minimization through reinforcement learning (60 citations) demonstrated how passive compliance and adaptive control can dramatically reduce power consumption in humanoid robots. In rehabilitation robotics, Tsagarakis introduced a high-performance, 2-degree-of-freedom over-actuated parallel mechanism for ankle therapy (78 citations), offering a mechanically simpler yet highly effective alternative to existing platforms. His work on modelling and simulation for humanoid locomotion, particularly for the open-source C-Cub robot, has provided critical tools for the research community. With a career defined by the integration of mechanical ingenuity and intelligent control, Tsagarakis continues to shape the future of human-centered robotics, making his research essential reading for students and engineers working at the intersection of biomechanics, machine learning, and robot design.
