Adapting to the technological evolution
The SMSS Research Group has been a center of excellence for Smart Materials research, teaching, and practice since its founding in 2001.
Dr. Bishakh Bhattacharya is a Professor, Department of Mechanical Engineering at IIT Kanpur, India. He is currently the HAL Chair for the period of Feb 2021 - Jan 2024, Member (Senate Nominee) of the Board of Governors (BoG) of IIT Kanpur and Coordinator, Centre of Excellence - Telemedicine & Robotics, Gangwal School of Medical Sciences and Technology, IIT Kanpur. He is the former Head of the Design Programme from 2011-2013. He also served as a head of Cognitive Science Programme and coordinated the Space Technology Cell of the Institute. He was a visiting professor at the University of Sheffield, where he researched on Structural Health Monitoring of Complex Autonomous Systems in collaboration with Prof. K. Visakan, Department of Automatic Control and Systems Engineering. He was also a visiting Professor at IPS-Waseda University, Japan and jointly developed a series of Pipe Health Monitoring robots with Prof. Harutoshi Ogai. As a DST-JSPS recipient, he is working in collaboration with Prof. Hiroaki Wagatsuma of Kyushu Institute of Technology, Japan on a Child Robot Interaction study. He is active in creating Web and Video-based course materials for India’s National Program on Technology Enhanced Learning (NPTEL) initiative.

This work presents a novel Shape Memory Alloy spring actuated continuum robotic neck that derives inspiration from pennate muscle architecture. The proposed design has 2DOF, and experimental studies reveal that the designed joint can replicate the human head’s anthropomorphic range of motion. We enumerate the analytical modelling for SMA actuators and the kinematic model of the proposed design configuration. A series of experiments were conducted to assess the performance of the anthropomorphic neck by measuring the range of motion with varying input currents. Furthermore, the experiments were conducted to validate the analytical model of the SMA Multiphysics and the continuum backbone. The existing humanoid necks have been powered by conventional actuators that have relatively low energy efficiency and are prone to wear. The current research envisages application of nonconventional actuator such as SMA springs with specific geometric configuration yielding high power to weight ratio that delivers smooth motion for continuum robots as demonstrated in this present work.
