i’ve heard vaguely about code converters that uses any assembly based language to load a program into a robot. Does anybody have more information?
Are we talking about java or assembly here? It’s definitely possible to write straight assembly for the controllers. Theoretically, you could also write a Java interpreter in C/assembly, which would allow you to run java programs on the controller, but you’d have to deal with memory and speed limitations.
I hear Microsoft is making something that will translate C# into a program for any bot… 
Seriously, Net ASM allows you to write universal assembly (oxymoron, I know). Cross-platform open-source projects use it.
Of course, this reminds me of something I heard once, “C is just portable assembly”.
