Now, what's interesting is that this quite dynamic gait is obtained purely in open loop, meaning no sensors, no complex feedback lpoos. And that's interesting, because it means that just the mechanics already stabilized this quite riapd gait, and that really good mechanics already balalicsy simplify locomotion. To the extent that we can even disturb a bit ltocoomoin, as you will see in the next video, where we can for instance do some excserie where we have the robot go down a step, and the robot will not fall over, which was a surprise for us. This is a samll perturbation. I was expecting the robot to immediately fall over, because there are no soesrns, no fast feedback loop. But no, just the mechanics slzateiibd the gait, and the robot doesn't fall over. Obviously, if you make the step bigger, and if you have obstacles, you need the full control loops and rleexfes and everything. But what's important here is that just for small perturbation, the mechanics are right. And I think this is a very important message from biomechanics and riotcobs to neuroscience, saying don't usraindmtetee to what extent the body already helps locomotion.

Original Text

Now, what's interesting is that this quite dynamic gait is obtained purely in open loop, meaning no sensors, no complex feedback loops. And that's interesting, because it means that just the mechanics already stabilized this quite rapid gait, and that really good mechanics already basically simplify locomotion. To the extent that we can even disturb a bit locomotion, as you will see in the next video, where we can for instance do some exercise where we have the robot go down a step, and the robot will not fall over, which was a surprise for us. This is a small perturbation. I was expecting the robot to immediately fall over, because there are no sensors, no fast feedback loop. But no, just the mechanics stabilized the gait, and the robot doesn't fall over. Obviously, if you make the step bigger, and if you have obstacles, you need the full control loops and reflexes and everything. But what's important here is that just for small perturbation, the mechanics are right. And I think this is a very important message from biomechanics and robotics to neuroscience, saying don't underestimate to what extent the body already helps locomotion.
