About

Raúl A. Castillo Cruces is a pioneer in cooperative robotic systems for computer-assisted orthopaedic surgery, where his work bridges the gap between autonomous robotics and human–machine collaboration. His research focuses on developing robotic arms that work in direct cooperation with surgeons, rather than replacing them, to enhance precision and safety during procedures. His most cited paper, "Improving robot arm control for safe and robust haptic cooperation in orthopaedic procedures" (2007, 15 citations), presents foundational methods for integrating navigated cooperative robotics into surgical workflows, emphasizing haptic feedback and robust control to ensure safe interaction. A subsequent study, "Cooperative Robotic System to Support Surgical Interventions" (2008, 8 citations), further advances this paradigm by combining 3D digitizing and navigation systems to improve instrument tracking and surgical accuracy. Castillo Cruces’ contributions have helped shape the field of computer-assisted surgery, moving it from purely navigational tools toward systems that actively assist and collaborate with surgeons. His work remains influential for researchers developing human-centered robotic systems in medicine, particularly in orthopaedics, where safety and adaptability are paramount.
