I am extremely new to robotics being 58 years old, but was hoping someone here might be able to give me some guidance;
I'm working on an idea that works much like a seesaw, is there a sensor that would send a signal to a servo or other device that would work 180 degrees from the signal? Meaning if a seesaw was up this would send a signal to offset that motion in direct proportion to it wioth the intent to always keep it in a level state? I'm so archaic I was thinking that a rheostat might be able to do it but I do hope we are way beyond that device for this problem. Any and all help is greatly appreciated.
