MABEL Bipedal Robot is Fast Enough to Run You Down

It was only a year ago that the University of Michigan's MABEL biped robot was breaking its ankles trying to walk over rough terrain. Now the robot is defying death once again by becoming the world's fastest bipedal robot, with the ability to sprint at up to 10.9 kph. More specifically, MABEL is the world's fastest "kneed" bipedal robot, which just means that it's the fastest robot that can run in a similar manner to us humans, leaving those Toyota robots (4.3 kph) and ASIMO (3.7 kph) in the dust.

MABEL is capable of such blistering speeds thanks to an innovative mechanical design which, although it may not look like it, incorporates a lot of the characteristics of a human runner. For example, MABEL has a torso that's substantially heavier than its legs, just like a human, and it's also got a system of springs that act like tendons. This gives MABEL a very human-like, bouncing gait, and the robot spends 40% of its time running in a "flight phase" with both feet off the ground, similar to humans:

For reference, MABEL's top speed of 3 meters per second probably isn't enough to catch a tolerably in-shape human, as Olympic sprinters can run at up to 10 meters per second over short distances. But the thing about robots is that they're determined, so in the end, it's a good thing that MABEL is tethered to that pole. And that it doesn't have any arms to grab you with. Or any vision sensors, either. So even if you can't run, at least you can hide.

For now.

The Bionic-Hand Arms Race

The prosthetics industry is too focused on high-tech limbs that are complicated, costly, and often impractical

A photograph of a young woman with brown eyes and neck length hair dyed rose gold sits at a white table. In one hand she holds a carbon fiber robotic arm and hand. Her other arm ends near her elbow. Her short sleeve shirt has a pattern on it of illustrated hands.

In Jules Verne’s 1865 novel From the Earth to the Moon, members of the fictitious Baltimore Gun Club, all disabled Civil War veterans, restlessly search for a new enemy to conquer. They had spent the war innovating new, deadlier weaponry. By the war’s end, with “not quite one arm between four persons, and exactly two legs between six,” these self-taught amputee-weaponsmiths decide to repurpose their skills toward a new projectile: a rocket ship.

The story of the Baltimore Gun Club propelling themselves to the moon is about the extraordinary masculine power of the veteran, who doesn’t simply “overcome” his disability; he derives power and ambition from it. Their “crutches, wooden legs, artificial arms, steel hooks, caoutchouc [rubber] jaws, silver craniums [and] platinum noses” don’t play leading roles in their personalities—they are merely tools on their bodies. These piecemeal men are unlikely crusaders of invention with an even more unlikely mission. And yet who better to design the next great leap in technology than men remade by technology themselves?
