This is really cool!
Would more taut crossed wires and a descending line for the grabber (like the one at an arcade) solve the humans crossing wire path problem? Then it becomes separate x/y and z.
A lot of rooms have fans and light fixtures too, another constraint to account for. I picture the wires taut and as close to the ceiling as possible
