A playground for automated RL env and physics simulations for Devin.

We've created playbooks (playbook/) for enabling Devin to create new physics environments with MuJoCo.

1. Run playbook mujoco_wasm.devin.md, take a snapshot to save sim environment
2. Modify and run mujoco_create_env.devin.md from snapshot for Devin to create a new simulation env (uses MuJoCo WebAssembly for live rendering.)

Render: node server.js

API:

• /api/pendulum POST for changing mass, length of rods, and initial parameters in pendulum.xml

• api/state GET request for getting the current state of the Mujoco environment in a parsable JSON format (eg. current position x,y,z of the mass and timestep)

Devin is instructed to create an RL environment with 2 red balls and 1 blue ball, and automatically spins up a MuJoCo instance with live rendering/web access and makes a PR. (demo below, 4x speed)

Built in a weekend with Devin technical preview (2nd place at Cognition hackathon)
