AI Learns to Run Faster than Usain Bolt | World Record

[@cozmouz]

Folks, yes there is air resistance! All bodies in the unity game engine have a setting for "Drag" to simulate fluid resistance. Gravity is set to -9.81. There is inertia and friction as well. The ragdoll's limbs have limited DOF (degrees of freedom) to simulate the human body. The only thing missing is energy cost and fatigue, which even-though sounds really cool, is extremely hard to implement in practice in reinforcement learning. This is primarily why the AI looked explosive towards the end despite having normal joint strength. During my experimentation with energy cost functions, the resulting locomotion is either: [1] almost non existent where the AI resorts to saving energy infinitely or [2] drunk/slow limb movement to save energy. I hope this clarifies any doubts you may have. Cheers!

[@S.I.M.P]

Did i just read FREEDOM?

[@joyul8216]

Now test this in real life.

[@LuisSilva007]

You also made it more explosive than any human

[@acenovaYT]

i mean he might have ran it faster but if he expends 3x more energy it kinda dosent count, if i had wheels for legs and a v8 for mucles i would "run" faster too. If the energy (useable and how much it can output via any movement) was considered and working the ai wouldnt be flailing its arms and doing wierd steps that are most likely wastefull (or its really the optimal way and we should all run like that though i think most would not be able to and would rip something via that way of running even if it is more efficient).

[@sferaefdeer3465]

Why is he running on two legs, maybe on all fours will be faster? A doll should love to experiment and test her abilities. People have tried various techniques to find the perfect one. Why is there only one doll? Several hundred dolls will increase the learning rate by the same number of times.

[@glutenfreecactus4147]

Bro I didn’t expect the -0.0005 penalty to actually make the AI run like a serial killer is behind them

[@brunomcleod]

It also consequentially made it scarier than how any serial killer could run Like I would not want to turn around and see that coming towards me

[@ViceZone]

So essentially, this AI is running for its life

[@daryladhityahenry]

Yeah right. I don't understand the logic behind this. How it is actually work? In theory, it just like reducing the reward right? How the AI know they must finished faster so they don't get pinalized since it's not even succeed in finish the race in the first place? Thanks.

[@manateeproductions5031]

@@me-cm8or nope not true, theres no emotions at all. the AI just goes faster because it learnt from previous runs that it gets a lower reward if it doesnt hurry up.

[@voxvolhynia5400]

The AI wanted to know what being human was like, so we implemented all aspects of reality: -Limb degrees of freedom -Mass/weight -Height & dimensions -Learning through experience -Air resistance -Friction -Inertia -Gravity -Penalty for existing The complete human experience.

[@LetFenrirSoloHer]

Optimal also takes into account the ammount of injuries you get. The Ai is fast because 1. it has no strength/endurance cap, nor does it experience pain.

A lot more people would watch running competitions if this was how contestants ran. Also a lot of reason why it runs like that is that it can't shift its joints or flex its upper torso.

[@rodrigomendes1980]

[@liam8370]

I don't like sports but if they ran like that I'll be the first in line to watch that sht

[@lememz]

crackhead olympics

[@nemovulture]

I also think that because when people run, they swing their arms by the side of their body, opposite to their leg to cancel the rotational force created by a leg swinging when running, and the AI even with limited range of motion, doesn't have a preference for what is "comfortable" in a sense for arm positions and learned that by swinging the arms above its head, required less speed by the arms to cancel out the rotational force, as the distance from the center of mass to where the arm is swinging is larger, it creates a larger torque on the body, better canceling the rotational force required to pull your leg forward for the next stride. However for most people, raising your arms above your head to run is uncomfortable and the marginal benefit to the AI isn't justified for actual people to use

I think what it needs is a reference for how to run to help it train better. It kinda reminds me of a baby, but it learns how to move around by watching the ones who raised it. Like feral children move like dogs. Also, it doesn't have to conserve energy and minimize physical damage to its body

[@dwsel]

Indeed I feel this model has different body parts weights and doesn't contain muscle model at all. It wouldn't be able to run in the real life.

[@TooHarshForYou]

But if we teach it how to run we will be defeating the purpose of the experiment. What we want to gather from this video is a new method to run which is seemingly undiscovered by humans but seems to be more efficient that humans run

[@xenaisu]

@@TooHarshForYou Nobody said this video is about finding a new way to run bro, no offence. We are talking about a game engine here if you read the authors comment right under his video you will even catch a glimpse of him saying that there are a lot of things that are out of his control/too hard to replicate in the engine. If this was real life the AI would face-plant just like at the beginning of this video, and say this was real life, and you could stick a human in it's position to do that exact run with all the same forces and movements. You would probably finish that run with both ankles dislocated and more than likely a few muscles pulled if not worse. Although I did notice the same thing that you have watching this video, I'm pretty sure that humans even at their peak would miss some really fine details that could improve ANYTHING that they are trying to accomplish. That is the human limit. Otherwise we would probably be watching a vertical aerodynamic beyblade with limbs that can push itself to the speed of light.

So, as i understood, to beat Usain Bolt you have to: 1 - Run with your hands up in the air 2 - Right arm should periodically smack your face or chest 3 - Run slightly leaning to the left 4 - Do not lean forward only, run leaning back sometime 5 - Do microjumps sometime too

[@sacr3]

The issue is that the human brain can only talk to its muscles at a certain speed. Our neural signals cap out at about 250 mph, they don't travel at that speed all the time that's only when it's extremely required, they typically travel around 80 mph. The time it takes for us to tell our legs to move back forward and plant the foot back on the ground is what's limiting us from going faster. The muscle tissue can only react so fast too, from tensing up as much as it can to push you forward and then to relax and then to do the same thing over and over again requires time and that is another limiting factor to how fast we can go. So of course you can program any bot you want to go faster than human beings, they have no real limitations aside from their gait. If you added limitations to their design where they can only contract their muscles so many times per second, or for example in the real world they use actuators and step Motors, which also have their own design limitations and how fast they can react and how much torque they can put out.
