Well, its been over a week since I last updated the blog, but in the meantime I've not been completely ignoring the code. I've added some improvements and will "release" an improved version with better error trapping in the next few days. But I have encountered a problem! Basically the backlash in the motors/gearboxes is such that moving the arm for 2 seconds in one direction is not "undone" by moving it for the same time in the opposite direction. I'm researching at the moment to see if the error is "per command", start/stop related or directional (e.g. gravity) etc. Once I understand the error I'll try to mitigate it (it probably won't be perfect but it has to be better than I get right now). Anyone found interesting ways to do this?
