Video Tuesday: BigDog, MABEL, and Quadrotors Landing on Quadrotors

Robots that walk, robots that run, robots that fly, and robots that amusingly fall all over the place: we've got videos

Video Tuesday: BigDog, MABEL, and Quadrotors Landing on Quadrotors

It's been a while since we've gotten an update from Boston Dynamics about their BigDog quadruped. And this isn't really an update, I guess, as much as a video of BigDog's noble robotic lineage, with a whole bunch of, shall we say, "outtakes" thrown in for good measure:

We know that the University of Michigan's MABEL biped robot is fast and all, but it's also had some issues in the past with taking the occasional bad step with painful results. It now looks like MABEL has learned some fancy new footwork, with this demonstration of her ability to not completely faceplant when confronted with a surprise 20cm step:

And lastly, I hope you're not burned out on quadrotors yet, because this is pretty sweet. Daniel Mellinger, Alex Kushleyev, and Vijay Kumar at UPenn's GRASP Lab have taught a big quadrotor to act as a landing (and launching) platform for a little quadrotor. Oh, and there's a bunch of hula-hoop dodging with multiple quadrotors at the end, too:

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?
