This looks like it ought to be able to use the same commands as an H-Bot. http://www.corexy.com
Two motors, differential turning moves the platform in X and Y. Hmmm, this looks pretty much exactly how an Etch-a-Sketch works. The "gantry" bar can be lightweight for a light load (like the end of a pattern torch arm) and it can float without need of guide/support rails at the ends. I could make a U shaped support frame, only need two motors at the ends of the U. The gantry could be a simple piece of aluminum flat bar and the carriage just a slider with a ball bearing with an ID big enough to fit over the drive magnet. Need to use it original style? Simply lift the bar up off the arm and run it back to the support post. ------------------------------------------------------------------------------ Precog is a next-generation analytics platform capable of advanced analytics on semi-structured data.
