In this video, we test a 3D printed gear pump and valve mechanism to control a double-acting hydraulic cylinder. The gear pump and valve mechanism are made entirely out of 3D printed parts, making it an customisable and accessible solution for controlling scale hydraulic systems. We show how the mechanism works by connecting it to a double-acting hydraulic cylinder and demonstrating its ability to control the cylinder's movements.

Like the Travel motors; the swing motor assembly also uses Ring Ratio Difference drive, which is like a compound planetary gear without a sun gear. This allows us to design gearboxes with high reduction ratios while keeping the assembly compact and parts count low. Check out @matttimmermans9583 video for detailed explaination: https://youtu.be/0WCPCJ3As8o The Slip Ring is a common 4 pin Audio Jack; this simple setup allows 360 rotations while maintaining electrical connections.
