Hi everyone, I leave you a link to the video with the first tests of a gripper built with hydraulics. It works quite well and it has a lot of strength, I am still with the initial tests but it looks promising. [image] Test hydraulic gripper.mp4 Google Drive file. …

I applaud your building skills and effort, but that is noisy, inefficient, and weak. With a simple DIY acme thread linear actuator driven by a small brushless motor with planetary gear, you could exert enough force to crush those objects (if you wanted). It would also be nice to have a reconfigurab…

Hi Darrel, thanks for your comment and contributions. As I mentioned in the post, this is the first test with the hydraulic system. This gripper is made with cheap and small RC hydraulic pump with light duty brushless motor, there are much more powerful hydraulic motor pumps if you want more streng…

Andres, i didn’t fully comprehend this part of your last post, prolly lack of sleep… In this way, no electrical part will be in the water and no component will have to be sealed with epoxy except for the penetrator, nor will it be necessary to build a specific watertight compartment to encapsulate,…

How about something like this? [gripper]

Hi Darrell, Excuse me, I probably expressed myself badly because my English is not grammatically correct. When I say that no electrical part will be in the water, I mean the hydraulic design that I shared in my post. Both brushless motors and ESCs, etc. will go inside a watertight compartment, the…

Hi Andres,
How did you manage to fix the jaws on the hydraulic cylinder?
Can you share your 3D Model?
Regards
