Robots are wonderful tools for research in biology. For instance, they can be used to watch animals in their natural habitat. EPFL scientists have designed and built remote-controlled reptiles to study biology. They have cameras instead of eyes and observe animals without disturbing them.
These reptilian robots have motors to imitate joint movement, an aluminum & carbon fiber structure, and a waterproof skin made out of latex. These robots also allow researchers to study animal locomotion and biomechanics.
