From: Optimizing toe joint stiffness to improve human-like walking
Metric | Min | Max | Relative change (%) | Sensitivity coefficient |
|---|---|---|---|---|
Optimization cost (\(\times\)106) | 8.07 | 8.42 | − 4.2% | 0.36 |
Step length (m) | 0.64 | 0.68 | − 5.9% | 0.51 |
Walking speed (m/s) | 0.98 | 1.07 | − 8.4% | 0.73 |
