About
Khemwutta Pornpipatsakul is a robotics researcher focused on advancing rehabilitation technology through innovative mechanical design and control. Their primary research areas include robotic rehabilitation for both upper and lower extremities, impedance control, and human-robot interaction. Pornpipatsakul’s most impactful contribution is a method for modulating joint stiffness to achieve Cartesian stiffness control in 2-DOF planar robotic arms for upper-limb rehabilitation (22 citations), addressing a critical gap in traditional impedance control approaches. They also developed a high-transparency linear actuator using an electromagnetic brake for damping modulation (14 citations), significantly improving safety in physical human-robot interaction. Their work on four-bar linkage planar arms (12 citations) highlights design advantages over serial robots for rehabilitation applications. More recently, Pornpipatsakul introduced the concept of a mechanical impedance tunnel for cost-effective desktop rehabilitation robots (4 citations) and developed an adaptive phase-shift control for independent crank ergometers in cycling rehabilitation (3 citations). Their research demonstrates a systematic approach to making rehabilitation robotics safer, more affordable, and more effective for stroke patients and others requiring physical therapy.
