- One SmolVLA run reports a loss of 0.013, yet the arm stayed at rest in daylight and failed to find the cups.
Field notes
The homepage groups the work by method and links individual experiment write-ups, including a dataset entry and a camera-guided approach that uses no markers. It also lists a wrap-up covering what was tried and what each run cost. The extract names natural light, a wrist-roll cap, and cup-centering as practical issues, but does not include the hardware model or detailed run data.
