In the past few months, we have covered plenty of bio-inspired robots here. EPFL scientists have developed a robotic crocodile & lizard to study biology. These creatures have a camera instead of eyes and can be used to observe creatures in their natural habitat. As the developers explain, these reptilian robots can also help in animal locomotion and biomechanics research.
The robots have motors to imitate joint movement, aluminum & carbon fiber structure for bones, and a waterproof suit made out of latex for skin. A mini computer is used to control 24 motors. More info is available here.
