Synthesizes Patrick Kenny's active inference framework with K-Scale's JAX/MuJoCo robotics stack for advanced predictive coding in robot locomotion.

This skill provides a specialized bridge between theoretical active inference and practical robotics engineering. It integrates Patrick Kenny’s discrete active inference framework with K-Scale’s JAX-based MuJoCo stack, allowing developers to implement predictive coding for robot control. By mapping concepts like Variational Free Energy and Mean Field updates to Reinforcement Learning patterns such as PPO gradient steps and entropy regularization, this skill enables the creation of sophisticated locomotion policies. It is particularly useful for projects involving Sim2Real transitions, hierarchical control loops, and bio-mimetic state estimation.
