Collaborative Robots Are Helping Fuel a Robotics Boom
A renaissance in small robots is blooming. Collaborative robots are inexpensive and tiny compared with the giant caged-in versions that dominate the automotive market. These new human-friendly robots work alongside human workers in the electronics industry, at auto suppliers, and in warehouses.
They are priced down-market to attract small- and medium-size manufacturers. Below $50K is generally the target pricing. Often these robots are the first step in automation for a small shop.
Rethink Robotics has mined this market for years with Baxter, and most recently, Baxter’s one-armed little brother, Sawyer. Major robotics companies have apparently decided Rethink shouldn’t have all the fun. ABB has introduced the small human-safe YuMi, and Universal Robots has introduced the UR3, a lightweight tabletop robot to compete in this market. These collaborative robots are highly flexible, able to perform multiple tasks, and they’re easy to program.

The market for small, flexible robots is growing at a time when robots in general are surging in popularity in plants across the globe. The International Federation of Robotics (IFR) released its annual scorekeeping card on robot sales this spring and announced record deliveries of 225,000 robots in 2014, up 27% from 2013 sales. More than half of the robots sold in 2014, 140,000 units, went to Asia. Of those, 56,000 went to China, 54% more than in 2013. South Korea was the second largest destination, with 39,000 robots, followed by Japan.
According to Arturo Baroncelli, president of IFR, 2014 was the first year robot sales exceeded 200,000. Automotive continues to be the leader in deploying robots. “The strongest drivers for growth were the automotive industry followed by the electronics industry,” said Baroncelli in the IFR report.
Some in the robot industry attributed this growth to the success manufacturers are having reaching ROI with their investments. Once the initial robot deployments are successful in reducing manufacturing costs, companies double down. “A customer starts with one or two, then they start to deploy dozens. Eventually they will have thousands of these,” said Jim Lawton, chief marketing officer of Rethink Robotics.
The low price of small collaborative robots that have entered the market in recent years may also be driving up purchase numbers. An inexpensive robot can produce a quick ROI. “From a costs perspective, the big number manufacturers need is a payback in 12 to 18 months,” he said. “The robot and the stuff supporting it need to come in at 50K or under. Compare that to other automation that generally costs far more than 50K.”
