Hi, I am in need of a system like the acro (OpenBuilds ACRO System ). I will be getting the BlackBox Motion controller too. I am trying to find all I need in one place if that's possible. I am trying to find out if I am getting what I need in hardware and specially software. I am really new to all the things discussed in this site, but I have an idea of what I need and the acro system seems the best option for me so far. I am not sure the acro system will work if I laid it out vertically, but I imagine it would be ok if my load is just a couple of pounds. basically I need a system that positions an antenna at various locations. Ideally I have control over x and y coordinates so that is why I am looking at the acro system with 1500mm by 1500mm frame. Also, It is really important to me that the software has some API, and by API I mean having a library of functions I can call from a main program written in C or Python. The main goal to me is to be able to position the antenna at some (x,y) point then take measurements. Next move the antenna to another (x,y) location and take a measurement.... repeat until done I seems that the software provided in this site does not have this API. Where do I start looking? Please let me know where to find open/free software that can be called from other code and allows positioning and monitoring of the position. Thanks!
