I worked for a defense contractor, and we had initial plans for a contractor to build us a wireless controller. Their controller was an ugly box-shaped controller that they wanted to charge us 200k. I redesigned the architecture of our system so that we could use an Xbox controller instead. There is no reason why these controllers can't be used over some other "industrial" controller, as long as you design the system appropriately to account for failures, which you should be doing regardless of what controller you select.
