TTK Center for Rehabilitation Research and Device Development

Indian Institute of Technology Madras


R2D2 is the TTK Center for Rehabilitation Research and Device Development at IIT Madras, headed by Prof. Sujatha Srinivasan of the Department of Mechanical Engineering. The group is involved in research related to human movement, and the design and development of rehabilitation and assistive devices for people with movement impairments.

R2D2 engineers affordable products for rehabilitation needs in India and beyond, works with clinical specialists, NGOs, hospitals, etc., to field-test the designs, and fosters a research environment to evaluate assistive device designs from biomechanical and functional standpoints.

Using appropriate technology, scientific methods and innovative translational models, R2D2 aims to enable easy accessibility and affordability of assistive devices and rehabilitation resources. R2D2 has successfully transferred technology to like-minded industrial partners including its startup, NeoMotion.


Chairman of TTK Prestige, Mr. TT Jagannathan has been a pillar of support for R2D2. He recently visited our center and took keen interest in our projects.


The first product from R2D2 was launched on November 05, 2019 in collaboration with industry partner, Phoenix Medical Systems! The Standing Wheelchair, named Arise, was launched at IITM Research Park by the Hon'ble Union Minister of Social Justice and Empowerment, Shri Thaawarchand Gehlot.
