What it does

The project explores turning a natural-language instruction into joint-space motion for a six-axis arm in a physics simulator.

My contribution

I am developing the simulator, goal-conditioned policy experiments and PyTorch-to-Unity closed-loop inference path.

Technical highlight

Language embeddings condition reinforcement-learning policies rather than directly emitting unbounded motor commands; the Unity loop provides the simulated control environment.

Results and status

This is in progress. It is a research prototype without a validated real-arm result or headline performance claim.
