ideas for intake that can stack cubes anybody have any ideas
You mean motorized or passive claws, hooks, or forks? Those are probably the ways we’ve seen cubes manipulated. There maybe others.
Out of these, it’s possible you can stack cubes using any of them. You can pick up one cube then drop it on top of another. Then pickup both cubes (probably from the bottom). The trick is can you do it well, would it be stable, and can you do it quickly?
Have you looked at other ways other than just stacking? Or have you already looked at other ways and decided stacking is the best?
