Simulation of snakes using vertical body bending to traverse terrain with large height variation
Yifeng Zhang, Qihan Xuan, Qiyuan Fu +1
Snake moves across various terrains by bending its elongated body. Recent studies discovered that snakes can use vertical bending to traverse terrain of large height variation, suc…
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…
Randomness in appendage coordination facilitates strenuous ground self-righting
Qihan Xuan, Chen Li
Randomness is common in biological and artificial systems, resulting either from stochasticity of the environment or noise in organisms or devices themselves. In locomotor control,…
Coordinated appendages accumulate more energy to self-right on the ground
Qihan Xuan, Chen Li
Animals and robots must right themselves after flipping over on the ground. The discoid cockroach pushes its wings against the ground in an attempt to dynamically self-right by a s…
Environmental force sensing helps robots traverse cluttered large obstacles using physical interaction
Qihan Xuan, Chen Li
Many applications require robots to move through complex 3-D terrain with large obstacles, such as self-driving, search and rescue, and extraterrestrial exploration. Although robot…
