About

T. S. Chandar is a robotics researcher whose work centers on robust control strategies for robot manipulators, with a particular emphasis on uncertainty and disturbance estimation (UDE). His most significant contribution is the development of UDE-based robust trajectory tracking controllers, which enable rigid link manipulators to maintain precise performance despite system nonlinearities, parameter variations, and external disturbances—a foundational paper that has garnered 135 citations and established him as a key figure in this domain. Chandar has further advanced the field by extending these principles into discrete-time formulations, as demonstrated in his 2023 work on discrete robust control, ensuring practical applicability in digital control systems. Beyond theoretical contributions, he has applied his expertise to socially impactful projects, notably co-developing "Sahayantra," a patient assistance robot designed to alleviate the burden on healthcare workers during the COVID-19 pandemic by reducing exposure risks and compensating for nursing shortages in India. With a career spanning foundational theory and real-world humanitarian robotics, Chandar’s work continues to influence both academic research and practical automation solutions.
