+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".
