Looks almost like the first version
This board may look familiar to some of you. Because at first glance, it looks just like its older brother described here: Dividing Head Controller. But many things have been improved in Revision B.
This post ist about the CNC conversion of a manual dividing head aka indexing head. If you’re not familiar with that kind of equipment, there’s a wiki page here. One makes use of interchangeable indexing plates and and the internal worm gear to accurately divide the circle. Parts like cogwheels and the like can be machined this way. A video of the finished project can be found here on my youtube cannel.
It’s been almost two years since I did (or at least started) this project but I never sat down to document it. That’s what I want to do today. As the title says it’s about a little robot based on a RaspberryPi. Like many of its kind it is driven by a pair of stepper motors each driving a wheel directly attached to the respective motor axis. At the back there is another smaller, pivotable wheel to keep the robot in balance.
