exoKNEE is an exoskeleton knee component to help restore mobility to paraplegics. The design involves a minimalist damping control that allows for free extension at all times, avoiding the use hydraulic or linkage systems common in pre-existing exoskeleton joints.
Rope-Wrench Mechanism
The mechanism allows forward rotation at all times for full extension of the knee. It locks at any position to prevent unintentional bending that causes collapses and falls.How exoKNEE Works

Future Redesign Considerations
• Smaller, thinner spring with lower strength to decrease torque • Lightweight expanding mechanism • Flat stepper motor for its compact shape and reliable control • Transmission system for better accuracy and modularity • Intuitive assembly for improved manufacturing and qualityShow More
