Repawse emerged from a growing recognition of the limitations faced by disabled pets and the need for more humane, intelligent rehabilitation solutions. Inspired by both news reports on prosthetics for animals and personal experiences with pet injury, Leijing Zhou sought to bridge the gap between human medical advancements and veterinary care. This project reflects a commitment to extending dignity and mobility to animals, harnessing technology to improve quality of life for pets and their caregivers.
What sets Repawse apart is its use of surface electromyographic (sEMG) control, a technology that reads muscle signals from a dog's healthy forelimb to predict and synchronize the movement of an impaired hindlimb. This active, real-time assistance ensures a natural gait, supporting efficient rehabilitation. The exoskeleton’s custom-fit design, achieved through 3D printing and precise body scans, offers unmatched comfort and biomechanical alignment, addressing the unique needs of each animal.
The realization of Repawse relied on advanced manufacturing techniques and carefully selected materials. Lightweight aluminum alloy forms the structural core, while soft memory foam lining and anti-slip rubber soles provide comfort and safety. The device is powered by a rechargeable lithium battery, ensuring practicality for daily use. Technical specifications include a compact form factor and integration of microcontroller-based control systems, highlighting the project’s focus on both function and user experience.
Developing Repawse involved overcoming significant challenges, particularly in interpreting animal muscle signals—a field with limited existing research. The design team conducted extensive field studies, EMG data collection, and iterative prototyping to refine the system’s predictive accuracy and mechanical performance. This dedication resulted in a device that not only restores mobility but also prioritizes animal welfare and comfort.
Repawse’s impact has been recognized with the Silver A' Design Award in 2025, celebrating its technical excellence and innovative approach. By transferring active-control exoskeleton technology from human healthcare to veterinary applications, Repawse sets a new standard in pet rehabilitation, offering hope and improved quality of life for disabled animals worldwide.
Repawse exemplifies how thoughtful design and cutting-edge technology can transform lives, inspiring future advancements in animal welfare and assistive mobility solutions.
