    "body_text": "Robot data is expensive, so it is difficult to study how behavior diversity changes as demonstrations scale. BURGER starts each task from a blank canvas and asks a robot arm to draw an object or spatial composition described in language, allowing many valid strokes and orders. Its prompt-driven pipeline generated 28,200 simulated demonstrations across 282 tasks. Evaluations of five vision-language-action models expose different failures in language grounding, spatial composition and motion generation; some systems benefited from greater diversity and scale and generalized to unseen compositions of familiar objects. A trained policy was also deployed on a Franka Panda arm and could draw reactively during human intervention. Drawing is a controlled proxy, not a general test of manipulation.",
