The ability to traverse unknown, rough terrain is an advantage that legged locomoters have over their wheeled counterparts. However, due to the complexity of multi-legged systems, research in legged robotics has not yet been able to reproduce the agility found in the animal kingdom. In an effort to reduce the complexity of the problem, researchers have developed single-legged models to gain ins...

In this Quick Guide, Lorentz et al. discuss the function of tetrodotoxin and its distribution in the animal kingdom.
