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!

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

[voxvolhynia]

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.

Finally, AI can show us the optimal way to run.

the ai's whole life goal was run, get treat, run faster, more treat, beat usain bolt

[BeastHighlightsOfficial]

8:49 this is proof all of us learned running wrong. To do it the right way, we need to stagger and flail our arms.

8:36 me omw to greet the woman walking alone at night (I'm such a good person)

[DylynKay]

7:42 bro took "now imagine youre being chased by a serial killer" to heart

[poppinoff]

8:35 Bro is fighting his demons while breaking Usain bolt's record, Respect.

[saiiiiiii]

Usain Bolt needs to adapt this technique

[etac]

This is me learning to walk again after standing up to fast and everything goes black for 10 seconds

9:03 Footage of me running to my bedroom after turning off the lights downstairs

[angrykrabs]

0:33 i really thought you we're going to say, "so lets fix it with a contorl shock".

[andrasbradacs]

I hope athletes will use this new technic of running at the next Olympics…

[conrails]

7:29 people in horror movies running away 💀

[duytdl]

He's not running, he's falling. He didn't (just) beat Bolt, he set the world record for longest stumble before a fall.

6:00 me walking to the fridge to get another beer

[SeanMirrsen]

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.

[arsicira]

this is insanely interesting to watch, its like watching a new life learning how to walk and run but in a youtube video, this might be a top 10 youtube video ive ever watched

[pmdgdyo]

in the end it looked like it was actually running from a serial killer
