Re:Build CEO Miles Arnone (@ReBuildMFG) argues manufacturers are putting too much faith in robotics to improve efficiency. "The problem with robots is that they're attacking a pretty small part of the total production cost. It's largely the elimination of direct labor." "Bringing robots in might take a few percentage points off your total cost at a very high capital expense." "You're much better off trying to implement something like Toyota's lean production system to eliminate all the steps along the way that are wasteful, that don't add value to the product." "In the U.S., we're very techno-centric and we like big step-change improvements. We want robots instead of grinding it out and every week just pulling a quarter or a half percent of the cost basis out by getting a little more efficient." "The 'I'm going to put robots here, get rid of all my labor, and all of a sudden I've solved my problems' approach won't happen."
