I've been in my trade, glazing, for almost 20 years now but never until this job had I ever used a remote controlled, hydraulic robo arm to set glass. These pieces of ballistic glass were around 600-700lbs and this robo arm picked them up and manipulated them into position like they were nothing. It was pretty impressive and I was glad to learn how to use it. this thing hung from a rolling crane, we would signal it close then use the arm to get the final adjustments and guide it into the opening. I used a cheap go pro knock off to film this so its not the greatest quality, I've since upgraded. It's kinda long but you don't have to see the whole thing to get the idea.
