RoboSimian Beats Out Surrogate for JPL's DRC Finals Spot

For the DRC Finals, JPL is betting on a robot that looks like a monkey over a robot that looks like a human

RoboSimian Beats Out Surrogate for JPL's DRC Finals Spot

We were very impressed with the creative design and solid performance that JPL’s RoboSimian demonstrated last year at the DRC Trials. But although RoboSimian was able to swing from trees and topple human society much more effectively than previous models, it seems that JPL itself wasn’t entirely sold on the optimalness (is that a word?) of its own design: immediately after the trials ended, they started building a new (and slightly more traditional) robot called Surrogate. Now, after six months of testing, the results are in.

It’s good news for RoboSimian: it gets to keep the top spot and will go to the DRC Finals next yearIf Surrogate looks sort of like it’s made out of three of RoboSimian’s leg-arms all stuck together, that’s because it was made out of three of RoboSimian’s leg-arms all stuck together, plus a pair of Robotiq hands, a sensor head, and tracked base.

Surrogate isn’t very humanoid looking, but you may say it’s more humanoid than RoboSimian is, with its flexible spine, arms, and upright posture. It’s about 1.4 meters tall, weighs just over 90 kilograms, and is much better suited for manipulation tasks, especially ones that require reach. For some DRC tasks, this might make it better than RoboSimian, but the tracks mean that it can’t negotiate rubble, climb ladders, or drive a vehicle without some seriously creative gymnastic feats. Also, Surrogate’s sensors are concentrated in its head, whereas RoboSimian has sensors all over the place, like its sides and belly.

It comes down to the fact that Surrogate is a better manipulation platform and faster on benign surfaces, but RoboSimian is an all-around solution, and we expect that the all-around solution is going to be more competitive in this case, says JPL’s Brett Kennedy. “[But] we'll continue to use it as an example of how we can take RoboSimian limbs and reconfigure them into other platforms.

JPL has released some videos demonstrating Surrogate’s navigation and manipulation capabilities. The two vids below show the robot operating two kinds of valve:

The Bionic-Hand Arms Race

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

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?
