Topic: Design and control of hand and leg exoskeletons for neuro-rehabilitation of stroke patients


The webinar will be conducted by IIT Gandhinagar on 3rd March 2021. The webinar will be conducted by Prof. Ashish Dutta Professor, Mechanical Engineering, IIT Kanpur, India.

Speaker Bio:

 Prof. Ashish Dutta obtained his PhD in Systems Engineering from Akita University, Japan, M.Tech from Jadavpur University and B.Tech from NIT Calicut. From 1994 to 2000 he was with the Bhabha Atomic Research Center, Mumbai where he worked on telemanipulator design and control for nuclear applications. Since 2002 he is with I IT Kanpur, where he is currently the Jag Mohan Chair Professor in Mechanical Engineering and Dean of Digital Infrastructure and Automation. He was also a visiting professor in Nagoya University, Japan in 2006 and is currently a visiting professor at Kyushu Institute of Technology, Japan. His research interests are in the areas of humanoid robotics, motion planning in 3D, intelligent control systems and rehabilitation engineering. He has over 100 publications in various international journals, conferences, book chapters, books, etc. Prof. Dutta has also served as member of advisory board of ISRO Chandrayan II Lunar mission (2009), member of Bureau of Indian Standards, Task force on Al of the Ministry of Commerce and Industry (2017-), Secretary of The Robotics Society (India) 2011-2017, etc.

Topic Abstract:

  • Patients suffering from loss of hand or leg functions caused by stroke or spinal cord injuries have driven a surge in the development of wearable robotic devices. This talk covers several aspects of the design, control and experimentation of hand and leg exoskeletons for rehabilitation of stroke patients.
  • The designs are based on the human joint motion trajectory, in order to emulate the motion of the varying instantaneous axis of rotation of the joint axes. The two finger exoskeletons are capable of simple grasping while the three finger exoskeletons are capable of fine object manipulation. The leg exoskeleton is capable of providing gait therapy.
  • A Brain Computer Interface that utilizes the wearers EMG and EEG signals controls the exoskeletons during neuro rehabilitation therapy. A challenge based impedance control system has also been developed that engages the patient during therapy and ensures effective robot-human cooperation.
  • Experimental results obtained during clinical trials with stroke patients prove the effectiveness of these devises.
