Dataset Description

SO-101 turntable pick-and-place (robot lil_guy), September 2026.

A single SO-101 follower arm, teleoperated from an SO-101 leader arm, picks a cube off a slowly spinning turntable and places it in a basket. Two cube colours (blue, green) and two operator speeds (slow, fast). Recorded with MakerMods Lab on 2026-09-27 and 2026-09-29.

Features (30 fps):

  • observation.state: 6 follower joint positions
  • action: 6 leader joint positions
  • observation.images.head: Intel RealSense D435if RGB, 640×480, overhead view
  • observation.images.head_depth: RealSense depth aligned to the head RGB, 12-bit lossless HEVC (decode with lerobot's depth support to get millimetres; values under 20 mm mean no reading)
  • observation.images.wrist: USB wrist camera, 640×480

The four datasets. This description is shared by four datasets built from the same recordings:

Dataset Episodes Contents
ewinchell07/so101-spinning-table-all 69 every recorded episode, including the failed demos and camera defects
ewinchell07/so101-spinning-table-success-head 63 successful demos with a clean head camera (RGB + depth)
ewinchell07/so101-spinning-table-success-head-wrist 25 successful demos with clean head and wrist cameras
ewinchell07/so101-spinning-table-failures 3 the three failed demos

Selection criteria:

  • Success: the cube ends in the basket, checked visually on the final frame. There are 3 failures, all with the cube knocked off the turntable.
  • Clean head camera:
    • no frozen head frames (at most 2 identical frames in a row)
    • every depth frame decodes
    • the two 2026-09-27 episodes with large teleop jumps (over 100 joint units in one frame, from a control-loop stall) are excluded
  • Clean wrist camera: at most 15% repeated frames, no hold longer than about 0.5 s, and no torn frames. The wrist camera has a failing connector. When it dropped out, the recorder held the camera's last good frame, so wrist streams outside the clean set contain frozen stretches.

Known issues:

  • 2026-09-27 session:
    • The head camera sat slightly differently; it was repositioned before 2026-09-29.
    • The wrist camera ran at about 16–20 fps, so 18–39% of its frames are repeats.
    • Episodes 7 and 14 contain the teleop jumps.
    • Episode 3's first depth frame fails random-access decoding. It is only in the all dataset.
  • The first head RGB frame of each 2026-09-29 session is overexposed while the RealSense exposure settles.
  • Task strings differ slightly between sessions, as typed at record time.
