+# ARX Pick Block Dataset
+
+This dataset was created using [LeRobot](https://github.com/huggingface/lerobot) and contains dual-arm robotic manipulation demonstrations for pick-and-place tasks.
+
+## Dataset Description
+
+- **Homepage:** [https://io-ai.tech](https://io-ai.tech)
+- **License:** Apache-2.0
+
+### Task Overview
+
+<video src="https://huggingface.co/datasets/io-intelligence/arx_pick_block/resolve/main/arx_pick_block.mp4" width="640" autoplay muted controls loop></video>
+
+This dataset contains demonstrations of a dual-arm robotic manipulation task where the robot picks up a block from a desk and places it into a plate.
+
+### Task Details
+
+- **Task Objective:** Pick up the block from the desk and place into plate
+- **Operational Objects:** Block
+- **Operation Duration:** Each operation takes approximately 8 to 15 seconds
+- **Recording Frequency:** 15 Hz
+- **Robot Type:** 7-DOF dual-arm ARX R5A
+- **End Effector:** Gripper
+- **Dual-Arm Operation:** Yes
+- **Image Resolution:** 640x480
+- **Camera Positions:** High; Low
+- **Data Content:**
+  • Robot's current state (8 joint positions)
+  • Robot's next action (8 joint commands)
+  • Current camera view images (dual camera setup)
+  • Task success score
