About

Razvan Andrei Budau Petrea is a robotics researcher whose work focuses on the critical intersection of safety, precision, and human-robot interaction. His key research areas include interaction force sensing, impedance control, and the use of series elastic actuators (SEAs) for compliant yet robust robotic systems. Petrea’s most cited work, “On the Interaction Force Sensing Accuracy of Franka Emika Panda Robot” (2021, 14 citations), addresses a fundamental challenge in collaborative robotics: accurately measuring interaction forces without additional sensors. By leveraging existing joint torque sensors, his research reduces system complexity and cost while maintaining reliability. His highly influential paper, “Safe High Stiffness Impedance Control for Series Elastic Actuators using Collocated Position Feedback” (2023, 13 citations), tackles the inherent trade-off between safety and stiffness in SEAs. Petrea’s innovative control schemes enable robots to display high endpoint stiffness without compromising safety, a breakthrough for applications requiring both precision and compliance. This work has garnered significant attention, with a related 2022 version also receiving citations. Petrea’s contributions are paving the way for safer, more capable collaborative robots, making him a notable figure in the field of physical human-robot interaction.
