Learn

Powered vs Passive Exoskeletons

Compare powered and passive exoskeletons by assistance, weight, charging, maintenance, control, failure modes and use-case fit — without a universal winner.

Learn

Exoskeleton vs Exosuit: What Actually Differs

Compare exoskeletons and exosuits by structure, load path, anchors and actuation, with research examples that show why the labels often overlap.

Illustration for Hip Exoskeletons: How Hip Assistance Systems Work

Learn

Hip Exoskeletons: How Hip Assistance Systems Work

Learn how hip-assist exoskeletons support flexion and extension, how rigid and soft systems differ, and which controller, fit and evidence limits matter.

Illustration for Knee Exoskeletons: How Knee Assistance Systems Work

Learn

Knee Exoskeletons: How Knee Assistance Systems Work

Learn how knee exoskeletons manage joint alignment, force transfer and control timing across rigid frames and soft exosuits, with study limits.

Learn

Exoskeleton Materials: A Component-by-Component Guide

Learn how carbon fiber, aluminum, polymers, textiles and padding serve different roles in exoskeleton frames, joints, anchors and body interfaces.

Illustration for Exoskeleton Joints: Degrees of Freedom Explained

Learn

Exoskeleton Joints: Degrees of Freedom Explained

Learn how exoskeleton joints use active, passive, polycentric and hinge-free mechanisms—and why degrees of freedom are not the same as motors.
