Martsinian/record-red-block-v3

This dataset was created using LeRobot.

Dataset Summary

• Task: Move a red block into a white box (pick-and-place / block-in-bin).
• Scene setup: The white box remains fixed in the workspace.
• Variations across episodes:
  • Red block position randomization: The block starts at different positions within a small neighborhood around the nominal start location (small translations).
  • Lighting variation: Ambient illumination changes slightly between episodes (e.g., intensity and/or direction), while the scene layout remains the same.
• Learning goal: Encourage policies that are robust to small spatial shifts and appearance changes from lighting.

Supported Tasks and Use Cases

This dataset is suitable for:

• Imitation learning with moderate domain randomization.
• Visual robustness experiments (sensitivity to illumination changes).
• Generalization evaluation for pick-and-place under small distribution shifts.
• Baseline comparisons against:
  • fixed block position / fixed lighting datasets,
  • block-rotation-only datasets,
  • position-randomized-only datasets.

Task Description

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

A typical episode includes: approach the block → grasp → move to the box → release into the box → optional return to rest.

With position randomization and lighting variation, successful policies should:

• localize the block under changing appearance,
• plan motion conditioned on current block position,
• maintain grasp reliability when shadows/highlights vary.
