You might remember the hilarious video showing several humanoid bots, including a few Atlas machines, toppling over, collapsing, and generally freaking out during a big robotic challenge held a few years ago.
So what’s going on? Has Atlas suddenly developed new ninja-like agility? Not exactly.
Navigating the real world remains a huge challenge for legged robots. Just balancing on two legs, in fact, takes extraordinary dynamic sensing and control. The accident-prone robots really struggled when trying to do something besides balancing, like opening a door.
The video does suggest that the latest version of Atlas has very impressive dynamic balancing capabilities. Without this, the robot would be unable to cope with the slightest slippage that naturally occurs when you put your foot onto a surface at high speed. This technology is the secret behind Boston Dynamics’ remarkable robot menagerie.
Marc Raibert, the founder and CEO of Boston Dymanics, says this version of Atlas uses some novel sensing capabilities to judge each leap. "To perform these tasks Atlas uses its vision system to align itself and measure distance on the approach to the obstacles," he says.
Raibert adds that the new systen also features some new hardware. He says it is significantly more advanced that the bot shown performing a backflip last year.
Impressive, but it's still a pretty controlled setup. Atlas also still requires a fair amount of human control. So, as cool as this new video is, it’s worth remembering that in the unfamiliar and unpredictable real world, a robot like Atlas is probably still more likely to trip and fall than run after anyone.
And if you’re really afraid, well, you can always just shut the door. (Unless this one is after you, of course).
