Thank you for the feedback! I believe it should be possible, considering the power a nema17 stepper motor that I used... Although I still need to figure out the control algorithms and the equations of motion and then eventually attempt the experiment.
The Brachistochrone Curve
Thank you for the feedback! In fact, my initial idea was to use a similar Flexi cable ribbon cable and use coiled cables and brushes from the rotating axle. But there were two reasons I didn't continue with this idea. 1. I felt the brushes may cause disturbances if the system was not made accurately and considering the communication technique that I used was i2c a single bit not transmitted correctly can cause a big problem. 2. Like I mentioned in the 16th step, I plan on replacing the IMU with a rotary encoder attached at the axis of rotation of the pendulum in the next version, this will completely eliminate dangling wires. :)
You are absolutely right. That is precisely why in step 16, I mention just that. I used an IMU simply because it was available at the moment, and plan on shifting to an optical encoder in the next version. I was aware of the drift that would occur while using a gyro+accelerometer setup, but this was regulated through software. Thank you for the feedback!
Thank you! :)
Thank you for the positive feedback!
