From the “What could possibly go wrong?” file comes yet another report that the US military is working to create robotic warriors that move more like humans than one of those robotic New York police dogs trying to walk on two legs and carry a gun. The latest technique under trial is something called ‘biohybrid robotics’, which in this case means replacing rods, gears and shock absorbers with real human muscle tissue. Are you ready for robots with bigger biceps than yours … or Arnold’s? “We look at a wolf in nature: It probably weighs about the same, can pull much more and can travel hundreds of miles without really eating, take a nap and do the same thing the next day.” ....
Modern army robots use batteries that power motors, which then drive axles and turn wheels. A biohybrid-powered robot would replace this entire system with lab-grown organic muscle tissue that might power artificial legs or other limbs. Electrical impulses or chemical actuation would control the muscles. A cheetah can run up to 50 miles per hour across uneven grassland, thanks to muscles and tendons. Could military robots do the same thing? AvalonGetty Images One of the major advantages of using organic muscle tissue is its inherent flexibility. Muscles and tendons can flex, pull, and give as an animal moves over mixed terrain, and especially as it encounters unexpected problems. ....
US Army Explores Equipping Robots with Living Muscle Tissue A scientist from the Army Research Lab gave a glimpse into its early work with biohybrid robotics. Looking to pave the way for the production of nimble robots that can move more like living creatures than bulky androids, Army Research Laboratory scientists are embarking on fresh, high-risk studies in biohybrid robotics that could eventually fuse organic tissue with machines. “This is wholly new to the lab, and the field itself is still relatively young. The publications associated with the first idea of successfully integrating muscle tissue or cells into some larger architecture to control motion with that same biological device didn t really start until after 2000 and really spooled up in the early 2010s. So it s very young, even as a discipline,” explained Dr. Dean Culver, a research scientist at the laboratory. “And that kind of gave us an opportunity to see how we could help move it forwar ....
