Robot Seal Plays Basketball Better Than You

The furry creature above? No, it's not Paro, the Japanese therapeutic robot seal. This hoop-shooting mechatronic harp seal is a creation of Taiwanese roboticists at the Industrial Technology Research Institute. The thing is not really a fully-actuated robotic animal; it's more of a manipulator arm disguised as a stuffed plush seal, with its multi-fingered gripper freakishly sticking out of the creature's mouth, for added Uncanny Valley-esque creepiness

The researchers claim their robot can convert hoops 99 percent of the time, but keep in mind it's shooting a toy basketball at close range (the maximum distance in the experiment was 3 meters). Still, watching this bizarre bot in action is utterly entertaining.

Jwu-Sheng Hu and colleagues described their robot at the IEEE International Conference on Intelligent Robots and Systems, last October, where they presented the paper "A Ball-Throwing Robot with Visual Feedback."

It looks like a simple stunt, but there's a good deal of tech behind it. The robot uses a stereo vision system to compute the position of the hoop in three-dimensional space. Based on that position, an algorithm determines the angle and speed the robot needs to launch the ball to hit the target. After some calibration procedures, the robotic arm does the rest. Watch out, LeBron!

UPDATE: I incorrectly attributed this work to researchers at National Chiao-Tung University. The robot was actually built at Taiwan's Industrial Technology Research Institute. National Chiao-Tung University collaborated in the project.

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?
