I once tried to build a two wheeled robot (like a motorcycle) that would balance by steering (just like a bike) - but I never did get a tilt sensor that was fast enough to stop it toppling over without also generating wild overshoots and basically (...) (23 years ago, 22-May-02, to lugnet.robotics)

For some reason, I didn't consider "centered" as a valid position... error on my part (big time). However, if the weight were spinning constantly, perhaps "center" and "tilt" could be determined... If the speed is constant over a full revolution, (...) (23 years ago, 22-May-02, to lugnet.robotics)

Luke (...) If you want super cheap, you could experiment making something like a mercury tilt switch but filled with salt water. The resistance will vary with how much of the electrodes are submerged. Peter (23 years ago, 22-May-02, to lugnet.robotics)
