Hydraulic system I am building a device that is based on controlled resistance in A SWINGING MOTION. The device has a swinging arm, swinging back and forth, like a golf swing, a tennis shot or a baseball hit. I want to create the resistance by moving oil from one side to the other side of a double rod small cylinder, through a controlled size orifice. I tested it and it works well and very smooth. I have already done the mechanical design converting the rotational motion to a linear motion and it’s in production already. We must cater for a right-handed and a left-handed swing. There will be 2 models. The one is totally manual and the other electronically controlled by a proportional flow control valve driven by a PLC operated by a UI. The manual unit is simple for me to build using this circuit: Let’s concentrate on the electric Robot ONLY. I found the valve that I want to use here are the specs and the manufacturer’s details. [login to view URL] [login to view URL] [login to view URL] I want to be able to control the resistance (both ways) from very high, meaning a highly restricted flow control all the way to slight pressure assisted helping the swinger in his training. That will give us full control for right and left-handed users. I hope it is clear but if not please ask me. What am I looking for: 1. A person with hydraulic experience with specific experience with proportional flow control valves and their software and control. 2. To take over a similar UI and make adjustments to fit the new system. 3. Program the control to and the system 4. Recommend additional or alternative hardware if needed 5. Test though video conferencing the operation 6. Start immediately and complete within 2-3 weeks 7. Good communicator and ability to do in English or Hebrew.

Hello, I have experience with hydraulic/mechatronic systems, motion-control integration, embedded control, and industrial automation involving proportional valves, PLCs, and user-interface driven systems. The application is especially interesting because it combines smooth bidirectional hydraulic resistance with programmable dynamic control for sports training. Based on your description, the system architecture would include: Double-rod hydraulic cylinder Proportional flow-control valve PLC/controller UI for adjustable resistance profiles Bidirectional resistance and assist modes for right- and left-handed operation I can assist with: Hydraulic control strategy development Proportional valve integration and tuning PLC/software programming UI adaptation for the new hydraulic system Hardware recommendations and optimization Remote testing and commissioning via video sessions Deliverables: Hydraulic/electrical control architecture PLC and valve-control software Updated UI integration Parameter tuning documentation Commissioning support A few questions before starting: Which PLC and HMI/UI platform are you currently using? What cylinder size and expected operating pressures/flow rates? Do you require programmable resistance profiles during the swing? Is closed-loop feedback planned? Will the valve be controlled via analog, CAN, or another interface? Best regards

Hi, I have gone through your project description and understand you’re building a hydraulic resistance system with a proportional flow control valve, PLC control, and UI-based adjustment for both right and left-handed swing motion. I have worked on automation and control systems involving PLC programming, proportional valves, hydraulic control logic, HMI/UI integration, and motion-based automation systems. I also have experience tuning control behavior for smooth bidirectional movement and assisted/resistance modes. For this, I would help configure the proportional valve control, develop the PLC and UI logic for adjustable resistance in both swing directions, recommend any required hardware improvements, and support live testing and tuning until the system works smoothly and reliably. Best regards, Juan
