Side story: the haptic feedback for the NanoManipulator was through a hydraulic system (kinda like this? https://www.sarcos.com/wp-content/uploads/history_5-339x280....). There were hydraulic lines that were piped through the building down to the machine room (where the SGI Infinite Reality Engine was!). Someone read through the manual and realized that the force that the arm was capable of could easily break someone's arm, and since it was usually grad students working late at night programming it, they decided it would be safest to just decommission that. I think I got one of the last demos during a UNC grad school recruiting event.
