AI Motion Intelligence
Advanced sensors continuously analyze your gait, movement intent, and terrain conditions in real time.
Natural Assistance
Feels Like Your Own Muscles
Human-in-the-loop reinforcement learning, combined with ≤50 ms response time, delivers smooth and natural assistance, avoiding the robotic feel common in traditional exoskeletons. It automatically detects motion states and terrain types, and adjusts assistance strategies in real time.
6-axis IMU + dual encoders
Millisecond response
Continuous gait learning
Personalized to Your Body
Weight Adaptation
Automatically calibrates assistance baseline based on your body weight, ensuring optimal support from day one.
Step Frequency Adjustment
Adapts assistance rhythm in real-time to match your natural pace, whether you're walking leisurely or running.
Fatigue Detection & Compensation
Senses when you're tiring and dynamically increases assistance to maintain your performance throughout the day.
Progressive Learning
The more you use Xtand, the better it understands your unique movement patterns. It becomes more personalized with every use.
Proven Energy Savings
Up to 50% Less Effort
Xtand significantly reduces lower-limb muscle load during stairs, climbs, and long-distance movement—delivering measurable performance gains you can feel and verify.
