North American firms send in the robots, even as productivity slumps

Published Mon, Aug 29, 2022 · 06:52 PM

NORTH American companies snapped up a record number of robots in the first half of this year as they struggled to keep factories and warehouses humming in the face of an extremely tight labour market and soaring compensation costs.

Companies ordered a record 12,305 machines in the second quarter valued at US$585 million, 25 per cent more units than during the same period a year ago, according to data compiled by the industry group the Association for Advancing Automation. Combined with a strong first quarter, the North American robotics market notched its best first half ever, the group said.

“Companies need to get product out the door – and so they need” new automation, said Jeff Burnstein, president of the Association for Advancing Automation, known as A3.

Eaton Corporation, for example, is working on 150 different robot installations over the next year and a half in its electrical equipment factories in North America.

The incentives for companies to pursue a robot-enhanced workforce are obvious in the current tight labour market. With nearly 2 open jobs for every unemployed worker, employers are bidding up wages: Total US labour costs – covering wages and benefits – surged 5.1 per cent year on year in the second quarter, the most since the Labor Department began tracking it in 2001.

Yet if robots are designed to make workers more productive, that is not evident so far: Those thick order books come as US productivity fell in the second quarter at its steepest pace on an annualised basis since the government began reporting it in 1948.

One possible explanation is the distortions caused by the Covid-19 pandemic. The crisis triggered huge shifts in the workforce, including an exodus of workers during the darkest days of the crisis. These workers are only slowly filtering back into jobs. It is normal for workers to be less productive if they are moving into new careers or changing jobs in their existing fields.

Moreover, much of the latest employment gains have come in lower-productivity service sectors like leisure and hospitality, which also may mask the improvements robots may be making elsewhere.

A3’s Burnstein said it also takes time for companies to fully implement new machinery to maximise its potential. “There’s a learning curve,” he said.

This is especially true in sectors adopting entirely new technologies, such as the auto industry’s turn toward electric vehicles. A3 found nearly 60 per cent of the robots ordered in the second quarter went to automotive companies.

Mike Cicco, chief executive of FANUC America, the US division of the Japanese robotics manufacturer, estimates half of his industry’s sales to carmakers are currently earmarked for new electric-vehicle factories.

“This is all investment for plants that won’t be up and running for several years now,” he said, so it is not surprising that those robots are not yet contributing to higher productivity.

The rush to add robots is part of a larger upswing in investment as companies seek to keep up with strong demand, which remains elevated even as the Federal Reserve has raised interest rates to rein in inflation.

Knapheide Manufacturing Co is among companies investing in new robots – including a new production line for flatbed truck bodies slated to go into its Quincy, Illinois, factory this year. The new line will use robots to feed steel parts through an automated welding process.

Mike Bovee, the engineer overseeing the installation, said the new robots should help ease a chronic shortage of welders. Knapheide currently recruits those workers from as far away as Texas.

“We’ll always need as many welders as we can find,” he said, but they can be redeployed to other parts of production at the 1,500-worker plant. REUTERS
