Found this interesting gripper. I'm playing with the design to see if it can be modified to fit the AR4. Love how the fingers wrap around objects.
That's really slick. keep me posted if you are able to make one, Id love to see pics or video of it.
I've been working on it intermittently for a couple of months, and finally today I launched the print of the last component.
I did a remix of Alaris' original designs and Chris' designs modeling a new platform to house the DS3225 servo. Not having a CNC machine in the workshop, I also replaced shafts 4 and 5 with off the shelf steel dowel pins, and modeled a new shaft 1 with a 4 mm through hole in which I inserted a reinforcing steel bar. Shafts 2 and 3 have been temporarily replaced by M4 screws, waiting for an better aesthetic solution, but for the moment they are doing their job.
At the moment I don't have much bandwidth available, but I plan to be able to carry out the first tests in the next few days, and once I have verified that the gripper works correctly, I plan to organize the bom, models and assembly instructions and publish here on the forum

@p-gabriele78 Looks great! Can't wait to see it in action. Thanks for the post.
I posted something similar a couple years ago. It was fairly easy to add to my AR3 and modify the AR software to control it.. https://anninrobotics.com/forum/robot-builds/servo-grippers?origin=member_posts_page
This is really cool! 🤙
