The days when only large companies could adopt automation are long past. Collaborative robots (cobots), lightweight industrial robot arms (LIRAs) and affordable peripherals such as vision systems and grippers have created a new paradigm by making low cost, easy to use automation solutions available to small-to-medium sized companies for the first time. 

In this application case study, we look at how a manufacturer of precision optical manufacturing and metrology equipment uses collaborative robots and a new robotic gripper/caliper to provide a solution that helps its customers optimize quality control measurements in the quality assurance area of their factory.

Originally made popular by the introduction of Rethink Robotics’ Baxter, so-called collaborative robots have created a lot of excitement around the industry over the last few years.

Robots in manufacturing is not a new idea. But today an increasing number of collaborative robots are joining the ranks, working alongside their human coworkers.

For decades, many manufacturers have counted on robots to tirelessly produce parts of predictable quality. One of the key attributes of robots is their repeatability, which means that their tool tip will return to the same pre-programmed location with a known and relatively small error.

At IMTS 2018, like at any industrial trade show, the predominant theme was Industry 4.0. Although Industry 4.0 still has not scaled up to cover a significant percentage of manufacturing setups, its vision of near-total automation—and the promise of resulting cost savings—has clearly captured the industry’s imagination.

The explosive growth of robots shouldn’t come as a surprise to anyone, especially in manufacturing. We are not quite to the level of a ‘90s action movie, but robots are certainly popping up in a lot more places these days. What may come as a surprise is the many ways companies are now using these robots, especially when it comes to metrology.
