Muscle tissue harvested from mice cells move ‘biohybrid’ robots
Sometimes nature provides the best blueprints for building effective robots. It can also provide the best material. Billions of years of nature selection
Billions of years of nature selection has built some pretty impressive machinery, so you can’t really blame engineers for borrowing a bit of inspiration from the world around them. The muscle fibers are attached to a “spring-like” device called a “flexure,” which serves as a kind of skeletal structure for the system. The flexures still needed to be tweaked to the specifications of the robot, ultimately opting for structures with 1/100 th the stiffness of the muscle tissue.
