Martsinian/record-red-block-v2

This dataset was created using LeRobot.

Dataset Summary

• Task: Move a red block into a white box (block-in-bin / pick-and-place).
• Scene setup: The block and the box stay in the same fixed positions across episodes.
• Variation: The red block orientation (rotation) changes between episodes, while its position remains the same.
• Learning goal: Provide a clean baseline dataset for imitation learning and debugging robot learning pipelines with minimal scene variation.

Supported Tasks and Use Cases

This dataset is primarily intended for:

• Imitation learning / behavior cloning (learning a policy from demonstrations).
• Policy evaluation and benchmarking in a low-variance environment.
• Ablations (e.g., impact of rotation variation on grasp strategy).
• Sanity checks for data loading, temporal stacking/windowing, and training loops.

Task Description

Instruction: “Place the red block into the white box.”

A typical episode consists of the robot starting from a resting pose, approaching the block, grasping it, moving to the box, releasing the block into the box, and optionally returning to rest.

Because the block position is constant and only its rotation varies, the task focuses on:

• grasp approach robustness to object yaw/roll/pitch changes (depending on how rotation was applied),
• consistent placement motion into a fixed receptacle.
