About
Xikai Tu is a prominent researcher in rehabilitation robotics and assistive exoskeleton systems, with a career dedicated to developing innovative technologies that restore mobility and independence for stroke survivors and individuals with neurological impairments. His most recognized contribution is the RUPERT wearable upper extremity exoskeleton robot, a five-degree-of-freedom, pneumatically actuated system designed for both clinical and in-home stroke therapy — a paper that has garnered over 143 citations and established him as a leading voice in accessible rehabilitation engineering. Tu's work consistently bridges hardware innovation and intelligent control, as demonstrated by his integration of functional electrical stimulation (FES) with robotic exoskeletons to enable reach-to-grasp training and gait rehabilitation. His more recent research advances the field further through data-driven reinforcement learning frameworks for adaptive hip exoskeleton personalization and human-in-the-loop optimization strategies, reflecting a sophisticated understanding of human-robot interaction. Across more than a decade of contributions, Tu has championed low-cost, patient-centered solutions — from bilateral telerehabilitation systems to hybrid cooperative control architectures — collectively accumulating hundreds of citations and meaningfully shaping how robotic rehabilitation devices are designed, controlled, and deployed in real-world therapeutic settings.
