Teaching robots to walk more like a human

When most of us first learnt to walk as toddlers, few of us would have
consciously contemplated the control algorithms of how we do it and
keep balance.

In a 5 December 2018 article at the Institute of Electrical and Electronics Engineers
(IEEE) Spectrum Magazine, Evan Ackerman reports on a research project at
Florida's Institute for Human & Machine Cognition (IHMC) to teach
robots to walk more like humans do.

Humanoid robots have a very distinctive walk. Knees bent, torso as stationary as possible. Even Boston Dynamics’ own Atlas uses this crouching sort of squat-walk to get around, because those perpetually bent legs are how it keeps from falling over. This sort of gait is so common with humanoid robots that it’s become the “normal” robot gait, but it’s also not at all the way that humans walk. We walk with straight legs, locking our knees with each stride, because it’s much easier to support our weight that way. You can try it for yourself: that bent knee “bipedal robot” walk gets tiring to keep up, because your leg muscles always have to be engaged.

At IHMC, roboticists are busy solving this problem by teaching Atlas to walk more like we do. In addition to making humanoid robots more efficient, a more natural walking gait could make them more versatile as well, able to handle more rugged terrain that robots that spend all of their time in a squat.

That's crazy hey? Did you see this one?



I know it's testing balance but it always makes me cringe when they kick them to try to topple them over. Reminds me of that Matrix movie trailer. How are we going to treat them eventually?

That one on ice is quite funny though when it's trying to keep straight.
