Real2sim first, then real: user reproduces Astra controlling a robot arm to paint

User @phamblnh reproduced a workflow of Astra controlling a robot arm to paint. To save tokens, the model first builds a real2sim reconstruction of the environment, moves the robot to check alignment, then draws trajectories that are validated in sim before transfer to the real robot. They painted a flower meadow this way, calling it proof of how strong the new model is at few-shot real2sim and robot control. The quoted post by @cdngdev had Astra figure out robot control itself to paint the Golden Gate Bridge, improving across attempts.
