Salamandra robotica II

Details

Salamandra robotica II is an amphibious robot inspired by the salamander's anatomy and nervous system. It's used to study robot locomotion and test neurobiological models in real environments.

HISTORY
The first incarnation of the Salamandra robotica, created at EPFL Biorobotics Laboratory, was a proof-of-concept design built with some modules from another robot called AmphiBot, in addition to some rudimentary leg modules. After that, the robot received major upgrades, and the EPFL team used the new design, the Salamandra robotica I, in several experiments. In 2013, the researchers unveiled Salamandra robotica II, which has more degrees of freedom (leg modules are not rigidly fixed to the body) and can walk and swim faster and more nimbly.
