i think you might need to watch rule R05 about entanglement

"If the structure of a COMPONENT permits easy penetration by an object less than 4”2 in cross section, it will invite detailed inspection.
Nets, loose rope or wire, voluminous sheets of fabric, etc. may be carefully inspected for these hazards. A ⅛” x ⅛” tight-mesh net (or very loose mesh fabric, depending on your point of view) may be a reasonable material that would not automatically pose an entanglement hazard. However, any flexible material has the potential to become an entanglement hazard if it is not firmly attached to an appropriate structure or left in a loose, voluminous configuration. Therefore, you must use your best judgment to determine if your particular use of the material will pose an entanglement hazard. Actual performance on the playing field will determine if the potential for entanglement is significant or not."

i know this sounds like it only applies to mesh, nettings, ect., but dont think of the rule necessarily but instead the safety/robot performance implications. A robot with a claw might be able to wedge itself into the framework for your arm, damaging the arm structure along with any wires that you are running up. to avoid this completely, you might want to put some plexiglass side covers on there or perhaps drill some holes in the arm supports and string up some fabric walls.
