Look what I made! Goodbye ClawGuy

It's the end of an era for me. My Arduino claw machine is off to the dump 😭 second child along the way and need the space. Couple of photos posted up for the sometime in the future when someone else goes to build one of these and they want to see how the mechanism worked.

Edit: if it makes anyone feel better, the phrase "the dump" is a catch all term where I live. It will actually go to a rubbish recycling facility who likely will place it in the larger appliances area for quite a long time and someone else will come along and think "I want that" and take it away to play with the whole things or the parts.

do you happen to have writeups about this?
My daughter would go crazy about it!

What did you use for claw? is it built around an old ender 3d printer?

already found that they sell the claws as replacement claws. Now I need to figure out if htere's a decent documentation

Yeah and the trick with the claws is to have three relays which provide three different voltages to it (12, 18 and 24 if I remember) and that allows you to control the grip strength in software.
