About

Krishan Kumar Gotewal is a robotics researcher specializing in gravity compensation, remote handling systems, and autonomous inspection for extreme environments, particularly nuclear fusion reactors. His most influential work, “A review on passive gravity compensation” (2017, 32 citations), addresses a fundamental challenge in articulated robot arms: the energy wasted on supporting their own weight against gravity. By analyzing gravitational torque from link mass, Gotewal provides design principles for passive mechanisms that reduce actuator load, improving efficiency and payload capacity. This contribution is critical for large-scale manipulators in manufacturing and hazardous settings. Gotewal’s applied research targets tokamak fusion reactors, where hostile conditions demand remote maintenance. He led the development of a prototype work-cell for validating ITER remote handling control standards (2016, 9 citations) and created a hyper-redundant robot for tokamak inspection (2017, 5 citations), enabling access to constrained spaces. His implementation of an OROCOS-based real-time controller (2017, 3 citations) ensures precise, safe operation in high-radiation environments. More recently, Gotewal explores deep Q-learning for robotic arm navigation (2018, 3 citations), advancing autonomous decision-making for tokamak inspection. His work bridges fundamental mechanics and cutting-edge AI, directly supporting the maintenance of next-generation fusion energy systems.
