robotwin_put_obj_cabinet_fixedArmTask_hybrid_100

This dataset was created using LeRobot.

Dataset Description

This is a 100-episode RoboTwin 2.0 put_object_cabinet hybrid dataset with fixed arm roles.

  • Composition: 50 official serialized episodes plus 50 paired native-path parallel episodes, totaling 23,807 aligned frames.

  • Fixed arm assignment: in all 50 serialized source episodes and all 50 parallel episodes, the left arm grasps, lifts, and places the object, while the right arm grasps and opens the cabinet drawer.

  • Meaning of fixedArmTask: the task roles never swap between arms. It does not mean that one arm stays static; the parallel half can move both arms concurrently while preserving the fixed roles.

  • Pairing: the parallel half is derived from the same 50 source scenes/seeds and was re-executed in RoboTwin at the native planner-trajectory layer.

  • Validation: both halves passed their dataset validation gates; the native-path parallel half passed 50/50 task-success and collision checks.
