I'm curious whether there's a better reference for gantry robotics? It looks like the hard parts here are non-mechanical, but I'd be interested to know more generally. Automated brick-layers come to mind as another 3D positioning task with no pitch or roll, but I'm not familiar enough with the general space to know if they're at all representative. Among other things, I seem to remember they can't corner properly, which suggests they might be operating on a linear axis and a width rather than a proper 3D workspace.
