My RC lawnmower project is progressing nicely. But the lawn mower I bought has a single lever deck height adjustment on it that I’d like to utilize if I can. I think I can make the geometry work, but need to use a more robust actuator than the standard 6 volt RC ones. I have what I think is a suitable model ( https://www.princessauto.com/en/detail/12v-dc-6-in-stroke-135-lb-linear-actuator/A-p8489072e ). It’s a 6" stroke, 135 lbs. model, but it only has the two wires: positive and negative (no potentiometer feed back).
Can I use a LAC board to control this without the pot feedback? I will always have line of sight to the mower and so can adjust the height from the transmitter, so I don’t need to define presets. I can configure a switch on my transmitter, so I think I need to do is make the LAC function like an H bridge switch. When I flip the transmitter switch on direction it lowers the wheels. There is a neutral center position on the transmitter switch that functions as off. And when I flip the switch the other way, it raises the wheels. The LAC board I have from this the RobotShop site is: https://www.robotshop.com/en/actuonix-linear-actuator-control-board.html
Is it possible to do use this board w/o position feedback from the actuator? Or do I need a different approach?
