DIY a Food-Grade Soft Gripper for Your Delta X S Robot for Just... $10

Welcome to the first video in our series of tutorials for applications with the Delta X S Robot.
In this tutorial, we're using food-safe liquid silicone, specifically Moulding Silicone Rubber, to create a soft gripper. This material is readily available on most e-commerce platforms, so I won't be providing a purchase link here. I purchased it in Vietnam for only $10, and I've been quite satisfied with the quality.
To follow along with this video, you'll need a 3D printer (FDM is recommended over SLA). Having a CNC aluminum milling machine and an air compressor would certainly be beneficial, but not necessary.
All necessary 3D files can be found at this link: grabcad.com/library/soft-grip...
For the demonstration video, I used the following equipment: a Delta X S V5 D800 4-axis robot, a Basler camera, two conveyors, one encoder, several vacuum pumps, and a few accessories. The program was written in Python using the PyQt5 and OpenCV libraries.
If you have any technical queries or are interested in discussing business opportunities, please feel free to email me at [e-mail].

amazing!

Could you provide some info on the vacuum pump please? I found it on your website, but I have a different application (ejecting small amount of fluids from special nozzles) where I would need positive and negative pressure and I don't want to buy two pumps. Can you tell me the exact model of the pump used? Big thank you! Amazing project!

[@muizzuddinazfar9363]

can I ask what diameter of tube and the tube connectors?

[@user-yr7sg3of3x]

I diy a robotic arm and soft gripper, but on the conveyor belt I can't get as silky smooth a grip on the object as in your video, can you easily point me in the direction of a gripping strategy?

What’s the brand of silicon you used ? Any link to it so that I can purchase it ?

[@lastmanstanding7001]

How can the Graeber track objects anywhere on the conveyor??

[@iitprep9588]

whats the OD of he tubes used?

[@benjaminjacobs4292]

hello, could you advise on what 3D printing filament is used for those white plastic pieces embedded in the silicone mold? I am working on a similar project of a different design, but need to embed some kind of filament in my silicone mold to properly affix each finger to a base for actuation. I've heard PLA doesn't bond well to silicone, and can't figure out what filament is used here. Thanks a lot!

I have the same question, Did you find a better material than PLA?

Hello, what are these connectors called?

Those are pretty standard ptfe fittings (otherwise called Bowden tube connectors). They’re on 3D printer and such. A quick google search will hopefully get you where you need. Just respond if you have another question.

Great video. I am interested to learn soft robotics. Could you provide the bill of materials (with an Amazon link if possible) that I need to purchase to make a DIY Soft gripper?

[@DeltaXRobot]

Thank you! I will try to find the items shown in the video on Amazon and will send you the shopping list soon.

Would love to get a hands on the shopping list. Thank you
