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…

Discovering Optimal Natural Gaits of Dissipative Systems via Virtual Energy Injection
Korbinian Griesbauer, Davide Calzolari, Maximilian Raff +2
Legged robots offer several advantages when navigating unstructured environments, but they often fall short of the efficiency achieved by wheeled robots. One promising strategy to…

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…
