This is cool. Researchers at MIT have developed a robot that can play Jenga.
At first glance, it doesn’t sound like much — computers can play chess, go and a variety of other games. What sets this apart, though, is that Jenga is a game that requires physically moving blocks around. And while this is relatively easy for humans, teaching a robot to move stacked blocks without collapsing the tower requires a collection of physical skills that has not — until now — been attempted with robots.
Combining interactive perception and manipulation – whereby the robot would touch the tower to learn how and when to move blocks – is extremely difficult to simulate and therefore the robot has to learn in the real world.
So the researchers placed a two-pronged industrial robot arm with a force sensor in its wrist by the Jenga tower and allowed it to explore rather than using traditional machine-learning techniques that could require data from tens of thousands of block-extraction attempts in order to capture every possible scenario.
It’s an impressive sight
