[MOC] Pick and Place Mechanism - Marble

[thebricky]

Hi Friends,

Here is my pick and place mechanism. With this tool, I was able to take the marbles from one place and put them in another place.

I bought the yellow  flexible rubber that comes into contact with marbles from the pharmacy, it was useful for me. You already know everything else I use.

Very creative use of pneumatics. Nice! 

[Toastie]

Absolutely: Very creative - and fantastic use of pneumatics!!!

I can watch that video over and over again.

Thank you very much for sharing!

Best regards,
Thorsten

This is great! Do you have a picture of what the tip looks like that actually picks up the marble?

[Erik Leppen]

Nice. It probably helps that the marbles are smooth (glass). Would this also be possible with GBC balls? Because, then you could expand this to be a GBC module.

Also, what I really like about the video is that it shows how it's actually built up.  It emphasizes the process, rather than just the result. More people should do this.

Nice machine and video! A good demonstration what can be done with pneumatics (vacuüm).

But I have a question, as with many Robot Inventor machines I've seen; The motors look like they pause few 100ms after finishing the movement, and then start the next motor. Did you actually program a wait block after each movement, or is it RI being slow? To me it looks like the RI motors react much slower than the EV3 for doing quick tasks one after another.

I don't think it will work with the normal GBC balls, as they have grooves to represent the segmentation of a soccer- or basketball. Even if they didn't have that, they'd probably have a molding mark, which would interfere with the suction when it happened to face the nozzle.

I'm not sure but there might be a difference between programming in code blocks vs. Python. The code blocks seem to have a slight delay when moving from one block to the next.

Very cool idea!  I like the music choice on the video as well

Very nice. I love the elegant minimality. Would be nice if there was Lego-only way to do it. Could a very carefully cut tube end work?

[Philtech]

Wow! Great build.

It could work with the marbles from PV-productons. These marbles don't have a molding mark and are completely smooth.

If they are indeed completely smooth (like glass marbles) then it should work. But any imperfection on the surface will break the suction effect.

Thank you. it looks like this.

Very cool!

Great Mechanism!

What's that suction piece called - I'd like to locate it at the pharmacy.

 

Thanks,

I bought the following infusion set from the pharmacy and cut out the piece I marked in red. It worked.

Thank you!  I have big Plans for this!  I really love your Pick n Place!  Great work!

If you running RI/Spike hub in live mode it's processing speed is different depending on your PC's processing speed. If your PC is slow, than code's processing speed become slow.
