Robot Learns to Clean Whiteboard, Schoolchildren Rejoice

Robots may steal our jobs, and apparently, our kids's jobs too, as Fujitsu's HOAP robot learns to clean a whiteboard

Robot Learns to Clean Whiteboard, Schoolchildren Rejoice

This is HOAP-2, and it likes to clean. It doesn't really know how to clean, but that's okay, because it does know how to learn. A human can move HOAP-2's arms in different cleaning patterns, and the bot will remember and then be able to clean by itself later on. Take a look:

The cool thing here is, of course, that HOAP is learning to erase instead of being programmed to erase. Robot learning is the focus of tons of research today. Now, in the case of HOAP, some people would argue that this is a waste of time, because robots should be able to detect marks on a whiteboard and erase them autonomously. And that's true, but it's also not the point.

If you're a teacher with a bunch of dirty whiteboards and no naughty kids and someone hands you a robot, you don't want to have to worry about whether your whiteboards are the right shade of white or the right size or whatever... And what if you have chalkboards instead? It really makes much more sense to have a robot be a generalist, and to be an effective generalist a robot has to be adaptable, something that (for now at least) robots are notoriously bad at. But robots are notoriously good at following instructions, so robots that can learn new tasks from humans on the fly have the potential to be much more effective, and much less frustrating for their users.

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?
