Our paper on energy landscape approach is published
We developed an energy landscape to understand the physical principles of probabilistic locomotor transitions in complex 3D terrain. For a model system of cockroaches traversing beam-like obstacles, using animal experiments and robotic physical modelling, we demonstrated that locomotor transitions of animals and robots on complex 3-D terrain correspond to barrier-crossing transitions on a potential energy…

Our paper on snake robot traversing large steps is published
We developed a snake robot with a partitioned gait and snake-like anisotropic friction and used it as a physical model to understand stability principles. The robot traversed steps as high as a third of its body length rapidly and stably. However, on higher steps, it was more likely to fail due to more frequent rolling…

Our paper on snake traversing large steps is published
We discovered that snakes partition their body to traverse large 3-D terrain like steps. By doing so, their can maintain near-perfect static stability while generating thrusts to overcome drag. This body partitioning strategy is conserved when terrain properties like surface friction and step height changes. We also observed similar partitioning for other types of 3-D…
