LOCAL PHYSICS PLAYGROUND
Make the tip meet the target.
Shape a strike. Follow the whip. Find a motion that lands.
Preparing the world
REPEAT THE EXPERIMENT
One strike is a starting point.
Vary target position and rope properties across repeatable seeds. Keep the outcomes and compare the recordings.

What this simulation measures
The rope is an inextensible elastic-rod approximation with a prescribed attachment motion. The robot arm shows the kinematically driven attachment chain; it is not a learned whole-body controller.
The pink target is a non-colliding distance judge: the tip reaches it when its swept path comes within the target radius. This does not simulate a balloon breaking. These local MuJoCo results use no trained policy or calibrated DeformX2 model. Physical whip-crack accuracy and hardware performance have not been validated.
Find swing compares 12 prescribed motions and records the best tested motion again. It changes the controller, never the selected target. This bounded search is not policy training.
Engine and model provenance will appear when local physics is ready.
