Robot tablecloth demo works via staged repair loop: rule-based checks plus learned policies

Komatsu-zaki explains why a robot tablecloth-clearing demo is so reliable: every task is split into stages with explicit success checks.

Pushing and positioning are rule-based functions (e.g. cloth extends >5cm past the table edge), while grasping and folding are learned policies. A failed grasp check sends the robot back to re-position and retry — a simple repair loop that makes the whole pipeline robust.
