Xtand Capricorn AI-Powered Knee Exoskeleton — Coming Soon | Pre-Order Now

Active robotic power for every step, climb, and descent.

The Xtand Capricorn is the flagship active knee exoskeleton in the Xtand Human Power Chain system. Engineered for high-demand sports, heavy mountain trekking, joint rehabilitation, and demanding physical work, Capricorn steps beyond passive dynamic compression to deliver real-time motorized power assistance. By continuously analyzing your biomechanics, it actively offloads joint torque, absorbs impact during descents, and propels your legs forward when climbing—giving you unmatched endurance and joint longevity.

Key Features

• Active Bionic Assistance & Torque Offloading

  Driven by active robotic motion algorithms, Capricorn senses muscle exertion and joint angles in milliseconds. It provides targeted motorized force assistance during leg extensions—reducing knee loading by up to 40% during steep ascents, heavy squats, and high-impact landings.

• Adaptive Gravity & Impact Shield (Downhill Protection)

  Descending steep trails or stairs places up to 4x your body weight on the patella. Capricorn’s intelligent braking and dampening system dynamically absorbs force on impact, eliminating joint fatigue and protecting cartilage during downhill movement.

• Real-Time Gait Analytics & AI Motion Recognition

  High-precision embedded IMU sensors evaluate your movement trajectory, step symmetry, and knee range of motion. Sync with the Xtand App via Bluetooth 5.1 to track live joint force, impact distribution, and long-term joint health trends.

• Ergonomic Carbon Fiber Core & All-Day Fit

  Crafted with ultra-strong, lightweight carbon fiber structural elements and breathable, high-performance textiles. Capricorn delivers rigid joint stabilization without restricting your natural movement envelope or adding uncomfortable bulk.

• Dual Operation Modes & Personalized Power Tuning

  Easily toggle between Smart AI Assist Mode (auto-adjusts force output based on movement speed and incline) and Custom Training/Rehab Mode via the onboard controls or the Xtand App. Fine-tune assistance levels according to your body weight, activity type, and target joint support.

Ideal Applications

• Mountain Hiking & Trekking: Carry heavy packs uphill and protect knees during long alpine descents.

• Athletic Training & Recovery: Reduce joint wear during high-volume workouts, squats, and functional training.

• Mobility & Rehabilitation: Provides active power assistance for users recovering from joint strain or seeking daily mobility confidence.

• Occupational Endurance: Reduces physical fatigue for active professionals, photographers, emergency responders, and field workers.
