@Veltrop: I don’t think they specified, but the implication is that it only works on bottles that can be squeezed. Thanks for the link; it wasn’t up on their site yet when I posted.

To sense if the bottle is empty or not, use the idea of a capacitor.
If the bottle is empty the charge in the ” condensator ” is diferent if the bottle is full. With this method , in theory will be able to tell which liquid is in the bottle because the charge that the “condensator ” keep is different from one to other.

I think that’s the concept that robot use.

93% accuracy with Odwalla bottles or any PET/plastic bottle? I’m guessing the former.

I don’t have audio on this computer, don’t know it it was mentioned in the video.
