Exploring Nonlinear Body Oscillations for Natural Quadruped Gaits
Annika Schmidt, Davide Calzolari, Arne Sachtler +13
Animals' body morphology shapes the gait patterns they can perform, where mechanical resonance reduces the need for active control. By tuning posture and muscle stiffness, they lev…

Locomotion of an Elastic Snake Robot via Natural Dynamics
Tristan Ehlert, Arne Sachtler, Annika Schmidt +2
Nature suggests that exploiting the elasticities and natural dynamics of robotic systems could increase their locomotion efficiency. Prior work on elastic snake robots supports thi…

Swing-Up of a Weakly Actuated Double Pendulum via Nonlinear Normal Modes
Arne Sachtler, Davide Calzolari, Maximilian Raff +5
We identify the nonlinear normal modes spawning from the stable equilibrium of a double pendulum under gravity, and we establish their connection to homoclinic orbits through the u…
