Wearable Robotics for Rehabilitation and Enhancement - 2021 - now

Cable-driven exoskeleton with series elastic actuators
Soft exoskeleton with power modulation units

We develop wearable robotic exoskeletons to improve the efficiency, speed and gait symmetry of walking or recover the motor function, especially for people with motor deficits or chronic stroke. Building upon comprehensive analysis of the human-robot interaction, our primary focus is to speed and systematize the design process itself by developing and using versatile hardware prosthesis and exoskeleton emulators and algorithms for human-in-the-loop optimization. We also perform basic scientific research on related topics, for example the efficacy of various assistance modes during walking. And we develop efficient actuators, such as linear series elastic actuators and power modulation actuators.

Intelligent Cane Robot for Walking Enhancement

Cane Robot V1.0 - 2021 - 2022

Intelligent Cane Robot with close range human following
Macnam wheel chassis with passive suspension

I have developed an intelligent cane robot V1.0 system with close range human following to assist user. The human following control effectiveness has been validated in outdoor experiments with six healthy subjects. The experimental scenarios included different terrains (i.e., straight, turning, and inclined paths), road conditions (i.e., asphalt and brick roads) and walking speeds. The obtained results showed that the average tracking error in the X and Y directions was less than 4.1 and 4.4 cm, respectively,

Cane Robot V2.0 - 2022 - now

Intelligent Cane Robot Adapt to different terrains (i.e., straight, turning, and inclined paths)
Macnam wheel chassis with active suspension

I have developed an intelligent cane robot V2.0 system with active suspension to assist user. The cane robot V2.0 maintains high stiffness while adapting to different terrains. The Cane Robot effectiveness has been validated in hospital with one post-stoke patient.
