Knee Exoskeleton

July 25, 2025

The Dnsys Z1 Knee Exoskeleton is a lightweight, AI-powered wearable designed to enhance mobility, reduce joint strain, and boost leg strength across a wide range of activities. Developed by a team of robotics engineers with backgrounds at DJI, Segway, and Xiaomi, the Z1 represents a leap forward in personal exoskeleton technology, offering real-time adaptive support in a form factor small enough to fit in a backpack.

Each unit weighs just 1.5 pounds and mounts to the back of the thigh and calf in under 15 seconds. Once activated, its dual 450-watt motors deliver up to 900 watts of combined power, lifting the thigh and pushing off the calf to assist with walking, climbing, squatting, and even cycling. The system uses torque, position, and force sensors to detect movement initiation and responds within 0.01 seconds, applying assistance precisely when needed.

The Z1’s onboard AI continuously learns the user’s gait and activity patterns, adjusting support dynamically for different terrains and motions. Whether ascending stairs, hiking steep trails, or skiing downhill, the exoskeleton reduces perceived effort and offloads up to 330 pounds of pressure from the knees. This not only improves endurance but also helps protect joints from long-term wear.

Battery life is extended with kinetic energy recovery during downhill movement to boost runtime. The system is IP54-rated for water resistance, making it suitable for outdoor use in varied conditions. Users can switch between assist modes via a companion app, with future updates planned for specialized activities like skiing and resistance training.
