Artificial Analysis shows AA-Robotics v0.1, a benchmark of models controlling a robot arm

Artificial Analysis published AA-Robotics v0.1, which has models control a robot arm and shows the task from the model's point of view. In an example where the same robot writes "hello world", Artificial Analysis says Claude Opus 5.5 dabbed it out dot by dot, with 3,270 arm moves over 34 minutes, while GPT-6 Astra wrote in continuous strokes, with 514 moves in 13 minutes.

These are Artificial Analysis's own measurements. More examples are in its article.
