Pretty cool.  I like it.

Can you share your laser cutter files or is this something robotshop will be selling?  It does seem a pretty nifty innovation on the theme.

Appreciated! File uploaded (can be found just below primary image). No plans to sell it for now, and it’s not really hard to create. 

The main issue is the fact that the parts were designed (and re-dimensioned) to be cut by one of our in-house laser cutters.

Cool project

It’s a nice project, thanks.

What foam did you use? Do you have any idea what kind of foams are used in the other grippers you presented?

Foam

It’s the same foam used on the A-style gripper:

It’s 1.25" x 0.25" thick weather-resistant, rubber-based black foam with adhesive backing. The density is 5-7 pounds per cubic foot and 5-9psi (firmness).

Not sure about the Little grip kit foam. When it comes to foam though, there’s really no exact science - getting the right size and dimensions and having a sticky back is hard enough, then if you have a choice after that, just experiment.

Will have to try it on the

Will have to try it on the makerspace laser cutter.  I am not sure what the width of that laser is on it.

Thanks for posting it!

Pleasure

Sketchup is really easy to use, so before cutting, you might want to modify the back to it can connect to something. Lucky you with access to a laser! Note that the driven horn / gear doesn’t have the spline drawn - Corel was used afterwards to include the more precise spline. If you have any other servo, you’ll have to adapt the spline for that servo (which takes some experimentation).
