About

Vinay Chawda is a robotics researcher whose work centers on the control of collaborative and rehabilitation robots, with a particular emphasis on physical human-robot interaction (pHRI). His most impactful contributions focus on enabling safe, intuitive, and high-performance interaction between humans and machines. A key area of his research involves the KUKA LBR IIWA, a lightweight robot designed for direct human collaboration. In his highly cited 2017 paper (32 citations), Chawda advanced torque control strategies for this platform, developing methods for smooth external torque estimation and inertial force cancellation—critical for detecting delicate contact events during interaction. He further refined these concepts in a companion paper (10 citations) by designing a low-latency tracking controller using KUKA’s Fast Robot Interface. Beyond industrial robots, Chawda has addressed the challenge of position drift in teleoperation systems, proposing improvements to the Time Domain Passivity Approach (22 citations). His work also extends to rehabilitation robotics, where he developed a low-cost force-sensing handle using force-sensing resistors (FSRs) to implement force-feedback controllers (7 citations). Through these contributions, Chawda has established himself as a researcher dedicated to making robots safer and more responsive for direct human collaboration.
