About
Renato Coral Sampaio is a robotics and automation researcher whose work bridges industrial repair, control systems, and biomechatronics. His primary contributions lie in developing specialized robotic systems for repairing hydraulic turbine blades damaged by cavitation erosion and cyclic loading—a critical challenge in hydropower maintenance. His most cited work (45 citations) presents a calibration method for laser triangulation scanners mounted on robot arms, enabling precise 3D surface mapping for automated welding repair. Sampaio has also advanced inverse kinematics optimization for five-degree-of-freedom robots, achieving model calibration that improves repair accuracy. Beyond industrial robotics, he has explored nonlinear model predictive control (NMPC) implemented on FPGA hardware with custom-precision floating-point operations, demonstrating real-time optimization capabilities. His work extends to machine learning, where he developed a multi-objective particle swarm optimization tool for tuning SVM hyperparameters. More recently, Sampaio has ventured into biomechatronics, analyzing lower limb exoskeletons for augmentation and rehabilitation. His research consistently addresses real-world automation challenges, from turbine blade restoration to control system hardware implementation, making tangible impacts on industrial maintenance and robotic precision.
