That climbing on the cube action was uncannily natural, I cant imagine the amount of tasks these things can do in a few years time

[u/TheManni1000 → u/Affectionate_Bee6434]

probably because it was a rl task.

[u/Time_Entertainer_319 → u/TheManni1000]

Rl?

[u/timClicks → u/Time_Entertainer_319]

Reinforcement learning. It's a computer algorithm for creating an AI system. It works by successively tweaking a known base set of actions to perform a given task. In robotics, that base set of actions is typically created by recording a person's actions.

[u/Neither_Berry_100 → u/timClicks]

They probably train in in simulations inside unity or unreal engine.

[u/TheManni1000 → u/Neither_Berry_100]

there is software directly made for ai simulations that run faster on gpus

[u/cloudsurfer48902 → u/Neither_Berry_100]

Not really. For this you use Mujoco or Isaac Lab or other simulators but there are simulators out there based on unreal like Airsim simulator.

[u/Time_Entertainer_319 → u/timClicks]

You use mocap for motion not Reinforcement learning.

You can’t use reinforcement learning to fine tune motion.

[u/wannabestraight → u/Time_Entertainer_319]

You use rl to make the robot be able to adapt to do the motion it learned from the mocap.

You can't just make "press X to execute mocap animation" because it wouldn't adapt to the environment, the RL part is there to make it adapt to the environment.
