I've gone down this path before. Ended up writing reward functions to reward foot height over time within a periodic gait cycle. Use this just to get them stepping, then use a curriculum to turn this reward off and let the policy find a more natural gait pattern by penalizing energy. Had to penalize foot sliding too because they get lazy haha

Interesting, what happened if you didn't do all that? Just weird motion, or didn't learn at all?

Super fun! I tried this in 2D once, though I used evolutionary methods - never managed to get RL working :/

Very cool! Can you explain a bit what you mean by evolutionary model? Randomizing weights in batches and move towards the winner? I'm using standard RL techniques (this one uses PPO)

I failed trying to make objects walk mechanically. Can you hear them screaming "kill me"?

Duuude! Finally someone doing (showing) game stuff related to AI models (that aren't just text/llm based). Massive potential here imo. The physics modelling could be huge too, but I guess the Teardown engine's physics is so optimised anyway it may not be needed! Exciting times!

Reinforcement learning is used to speed the production of behavior for the Boston Dynamics Atlas humanoid robot. At the heart of the learning process is a physics-based simulator that generates training data for a variety of maneuvers.

Learning a new skill is can be so overwhelming. But try taking baby steps instead. Ps: if you have any YouTube recommendations you feel would help me in my learning process with Framer, share them with me. #uiuxdesign #WebDevelopment
