No...no limit switches. If I were to do it again--extremely doubtful--I'd take your and Industen's advice and learn about them.I was wondering if you had limit switches in your setup as running the system "open loop" usually isn't viable for more than a couple of operations. Using limit switches to activate forward / reverse on the motor would automate it, but having the speed ramp up and down would be best.
A lot of CNC machines have two limit switches for each end of each axis. The first (inner) is the "soft limit" that signals to the controller that it should go no further. The second (outer) ones activate the E-stop and should never be reached in normal operation. When one of these activates it can cut the power as the controller possibly has lost control (damaged output driver), locked up or one of the soft limit switches has failed.
Probably more than you wanted to know, but it may give ideas to someone else that goes down the path.
Thanks. I appreciate the kind words.What I saw in the video was an amazing prop that pretty much did what you wanted. To even get as far as you did in building it and getting it to work the way it did still blows my mind. I hope that you don't abandon the prop entirely and that it will see it's return in some future haunt. Maybe you can find someone who builds robots (like the ones in the video linked below) who could help you design a different way to move the cart the skellie rides on.
Thanks. I used Wildfire blacklight paint. The optical white paint is a standout, but the orange, blue and green didn't have nearly as much brilliance. I had to mix some of the white with the others to make the prop more visible.Very impressive setup! The lighting on the unicycle skelly is perfect!
