Our next presenter is Jonathan Gosyne, who's talking about "Going Off Road, Moving in Sand, Snow or Mud". Okay. So let's talk about movement. And more specifically, let's talk about how robots move and how devices help us to. Now I'm sure you've seen Atlas dancing and spot dancing from Boston Dynamics on YouTube. And I'm sure you've seen the Olympics where the Olympians like Blake leaper up a few, performing almost superhuman feats of movement with their race played prosthetics. Now the thing about these devices is that they worked exceptionally well in the contexts for which they are made. However, when you take them, when you put them off road and sand, snow, mud, dirt. Unfortunately, that functionality becomes it begins to fall apart. Nature, however, does not have this problem. When we look at the animal kingdom, we see, while I may not be great on sand myself, admittedly, you have Austria, lizards, rattlesnakes, and all these creatures have this beautiful morphology and biological control, how they're built such that they move quickly and efficiently. And these unstructured environments. And so they not just survive but thrive. So this begs the question, can we learn from that? Can we leverage what we see in nature to perhaps make ourselves move more quickly, more efficiently, and design our device is better. Well, here's how we're gonna address this problem. Two steps. First of all, we're going to start with a simulation of someone I knew what I had was a really simple simulation or someone running, walking, hopping on hard ground and understand why a simulation, because you can look under the hood and see what exactly is different. Then. Once we see, but we want to focus on, we put a real human being and a real lab to perform the exact same task. Now, what we actually found is that it's not necessarily, not necessarily at the standard sinking. Or did you have to let your legs higher but your muscles actually work less efficiently. Sand in snow and in mud, that this is good news for me because I know that exoskeletons can make your muscles work more efficiently. So what do we do? Well, let's go back to the simulation and let's pull some knowledge from the animal kingdom, from literature and fine tune this exoskeleton in this simulation to get the results that we want. Now it is a simulation. Again. Now we take the same exoskeleton and put it on a human being again. And we put them in lab again. And what we actually found is that by putting this exoskeleton on a human being, you can actually bring the energy cost of running and walking on sand, snow and mud right back down as if they were performing that same task on hard ground. This is huge. This has implications for healthcare, defense, an aging population and beyond. And really helps us to restore our quality of life to folks who really, really need it. And for me as an engineer and for us at Georgia Tech, this is great because it allows us to be part of the movement that is designing devices with people. For Pete. Thank you.
