If you want to make your own I've included the artwork in negative for use with the dry film photo resist process. This board would need two jumpers on the two pairs of relay/motor outputs that are end to end (+ to - and - to +) >> only one can be 'on' at a time. Gripper (previously posted) https://www.thingiverse.com/thing:3447594 I'm happy to answer any questions about the construction and or upload more detail pics. See a video from the ROV in action. In this video the claw is folded back under the ROV so it is in Camera Only Mode: https://youtu.be/eNyRvkDXL-M In this video I use the claw to retrieve from the bottom. The last part of the retrieve is done via the cable/ 400lb test tether. https://youtu.be/YdAvQyoZjMA
