Cockroaches adjust body and appendages to traverse cluttered large obstacles

Yaqing Wang, Ratan Othayoth, Chen Li

To traverse complex natural terrain, animals often transition between locomotor modes. It is well known that locomotor transitions can be induced by switching in neural control cir…

Locomotor transitions in the potential energy landscape-dominated regime

Ratan Othayoth, Qihan Xuan, Yaqing Wang +1

To traverse complex three-dimensional terrainwith large obstacles, animals and robots must transition across different modes. However, the most mechanistic understanding of terrest…

Shape-induced obstacle attraction and repulsion during dynamic locomotion

Yuanfeng Han, Ratan Othayoth, Yulong Wang +4

Robots still struggle to dynamically traverse complex 3-D terrain with many large obstacles, an ability required for many critical applications. Body-obstacle interaction is often…

An energy landscape approach to locomotor transitions in complex 3D terrain

Ratan Othayoth, George Thoms, Chen Li

Effective locomotion in nature happens by transitioning across multiple modes (e.g., walk, run, climb). Despite this, far more mechanistic understanding of terrestrial locomotion h…

Dynamic traversal of large gaps by insects and legged robots reveals a template

Sean W. Gart, Changxin Yan, Ratan Othayoth +2

It is well known that animals can use neural and sensory feedback via vision, tactile sensing, and echolocation to negotiate obstacles. Similarly, most robots use deliberate or rea…
