Kevin Zakka (Google DeepMind) released mjbatch, an open-source Python tool that steps thousands of MuJoCo physics simulations in parallel on your CPU, no GPU required.
- He built several self-contained examples demonstrating how far the primitive can go
- User @aPrest96 reported solid results after just 15 minutes of training on a MacBook Air M2, praising Zakka for consistently shipping and open-sourcing useful tools
A notable throughput primitive for robotics simulation and RL training workflows.
