Research questionHow can quadruped robots exploit nonlinear mechanical resonance to produce multiple gaits without separate controllers?Quadruped robots typically require separate locomotion controllers because their nonlinear mechanical dynamics are difficult to predict. This limits their ability to use resonance and morphology to generate efficient gaits across different speeds.

Six nonlinear normal modes were identified and validated in simulation and hardware; black-box optimization of step length produced distinct speed-specific gaits, which largely transferred to the robot.research paper · Sep 9, 2026
