Chulalongkorn University Unveils Exoskeleton Wheelchair to Aid Mobility

BANGKOK,March 4, 2025/PRNewswire/ --Chulalongkorn University has introducedthe Exoskeleton Wheelchair, an innovative robotic suit designed to help people with disabilities stand, walk, and move more independently. The breakthrough was developed byAssoc. Prof. Dr. Ronnapee Chaichaowarat from theFaculty of Engineering,aiming to improve mobility beyond traditional wheelchairs.

A New Frontier in Robotics

The robotics lab atChulalongkorn University, located on the 9th floor of Chulapat-14 Building, serves as a hub for students and researchers fromThailandand abroad to collaborate on cutting-edge robotics projects. Dr. Ronnapee envisioned this lab as an alternative learning space, where students build and test robots through hands-on experimentation.

The World's First Thai-Made Exoskeleton Wheelchair

Nicknamed"Thai Iron Man,"this innovation is the first exoskeleton wheelchair built by Thai researchers. Unlike conventional wheelchairs, it can transform to help users stand and walk, making it easier to navigate stairs or public transport. The project received funding fromThailand'sNational Research Council(NRCT) in 2021–2022 and was a finalist in the 2024 Young Technologists Award.

How It Works

The Exoskeleton Wheelchair is a wearable robotic device that supports users by combining a wheelchair and exoskeleton into a hybrid system. Made with lightweight carbon fiber, and equipped with foldable wheels, the robot allows users to switch between sitting and walking modes with ease. A motorized system controls hip and knee joints, while the ankle joint remains flexible to ensure natural motion.

Engineering Meets Human Anatomy

Dr. Ronnapee integrated biomechanics and kinematics compatibility to create a device that mimics natural human movements. The exoskeleton must align with the user's body to prevent discomfort or strain. A four-bar linkage system was implemented to enhance flexibility, ensuring the device moves in sync with human joints.

Challenges and Future Development

The prototype cost130,000 bahtand was funded by research grants. However, Assoc. Prof. Dr. Ronnapee believesThailand'saging population will drive demand for wearable robots. The team is currently developing a second prototype with improved stability for standing and walking. Clinical trials with patients are planned, pending Research Ethics Committee approval. If successful, this Thai-made exoskeleton wheelchair could revolutionize mobility assistance and positionThailandamong global leaders in robotics.
