The Department of Robotics and Automation, Paavai Engineering College, organized an online guest lecture on “Metal to Muscle: The Magic of Shape Memory Alloys in Robotics” on 26th September 2025 through Microsoft Teams. The resource person for the session was Dr. Avinash Kumar, R&D – ITQ Engineer II, General Mills, Powai, Mumbai. The program was coordinated by Dr. R. Rajeshkannan and Mr. K. Mohanraj, under the guidance of the Convener, Dr. V. Subburam, HoD/R&A, and Patron, Dr. M. Premkumar, Principal.
The lecture was organized to provide insights into the emerging role of shape memory alloys (SMAs) as artificial muscles in robotic systems. Dr. Avinash Kumar began the session by explaining the motivation behind using SMAs, emphasizing their unique ability to transform from inert metal to dynamic actuators that mimic the function of biological muscles. He introduced the fundamentals of SMAs, covering the concepts of shape memory effect, superelasticity, and phase transformation between martensite and austenite.
He highlighted the advantages of SMAs—such as compactness, lightweight structure, silent operation, and high energy density—while comparing them with traditional actuators like motors and hydraulics in robotics. The lecture also showcased real-world applications, including soft robotic hands, wearable assistive devices, biomedical tools, and morphing aerospace structures, where SMAs provide flexibility and adaptive motion.
The session concluded with an interactive Q&A, which enabled participants to clarify their doubts and deepen their understanding. Dr. Avinash Kumar inspired the audience to explore the future potential of SMAs in robotics, particularly in the development of soft robots, assistive technologies, and energy-efficient actuation systems.
