One of the latest robots out of the Swiss Federal Institute of Technology in Lausanne (EPFL) can mimic the way a real salamander moves, whether on land or in the water. The EPFL scientists call it Pleurobot (after the species Pleurodeles waltl) and designed it after studying x-ray videos showing the amphibian walking and swimming. According to the institute, other scientists from EPFL had built salamander robots in the past, but this has the most realistic movements thus far. It's also the first one that's "accurately based on the 3D motion of the animal's skeleton."
The lowest level of electrical stimulation in salamanders' spinal cords is associated with walking, while the highest is associated with swimming. As such, the machine can help scientists explore the relationship between spinal cord stimulation and a vertebrate animal's movements. In the future, this could lead to neuroprosthetic devices for both amputees and paraplegic patients.
