| This dataset was created using [LeRobot](https://github.com/huggingface/lerobot). |
|
|
| ## Task description |
|
|
| The objective of the task is to grasp and place colored cubes in a 2x2 grid, using a SO-101 robot arm. Two cameras were used to visualize the scene. |
| |
| The task to achieve is decomposed in three sub-tasks ordered by difficulty: |
|
|
| - level 1: pick a single black cube and place it in a cell of the 2x2 grid. The cell is indicated by a black cross and is always at the same position (top-left cell). |
| - level 2: same as level 1 but the target cell can be any cell in the 2x2 grid. |
| - level 3: pick two cubes (one black and one green) and place them on the cells marked with the corresponding colored crosses in the 2x2 grid. |
|
|
| Each level was the occasion to record a new dataset specific to the level to complete. |
|
|
| ## Dataset Description |
|
|
| This dataset contains a set of teleoperated demonstrations collected during a two-day hackathon using the LeRobot library and SO-101 robot arms in a leader–follower setup. |
| Each episode shows the follower arm picking two colored cubes and placing them onto the matching colored crosses inside a 2×2 grid. |
|
|
| Two RGB cameras were used: one facing the follower arm and one looking at the follower arm from a +45° perspective. |
|
|
| The background was masked with cardboard and wood panes. Ambient lighting varied throughout the day. |
|
|
| ### Episode Protocol |
|
|
| 1- Start with the black cube: grasp and place it on the cross |
|
|
| 2- Go back to the starting position. |
|
|
| 3- Repeat with the green cube (task 3). |
|
|
| 4- Go back to the starting position. |
|
|
| ## Variability |
|
|
| Data were recorded with 3 different persons that manipulates the leader arm, each one with its own "style". |
