Watch these mini cheetah robots do backflips and play soccer at MIT on a fall day. The four-legged robots are powered by 12 motors and can run around untethered from cables.
On a recent fall day at MIT, a group of players kicked around a soccer ball on the school's Killian Court lawn. They ran around and jumped in piles of leaves. They even did backflips.
But these weren't students, they were cheetahs. Mini cheetahs, actually. Oh, and they're robots. MIT's Biomimetic Robotics Labratory, which sits across the lawn from the school's iconic main building, created these so-called mini cheetahs, four-legged robots that are powered by 12 motors.They can run around untethered from cables, steered by nearby researchers using an RC-like controller.
Watch this robot thread a needle 01:17Ten years later, the team has created three versions of a larger cheetah robot in addition to the mini cheetah.Unlike actual cheetahs, which have a top speed of up to 75 miles per hour, the robotic mini cheetah' can run only about around 9 miles per hour. But both have what Kim calls"physical intelligence." "People don't realize how difficult it is to stay balanced," he explained.
That viral video of a robot being beaten up isn't real 00:57Working with the same hardware, the researchers will be able to share information and develop algorithms more quickly, Kim said. One particular skill they're working on: climbing stairs. It's a key advantage that a four-legged robot has over one that moves on wheels or tracks.
