Rosheim, a modern robotisist, build a replica of Leonardo's moving knight. Rosheim's knight attempts to vastly improve on the original design of Leonardo's with modern technology while still having human-like motion. It is powered by linear actuators acting as muscles and has human-like joints, as opposed to the joints typically found in industrial machinery. This replica was sent to the Jihnson Space Center's Dextrous Robotics Laboratory. Because the robot was human-like, it was designed to do dangerous manual tasks that would have otherwise required the full dexterity of an able-bodied person.
