Automation has a reputation problem. It's often painted as something reserved for massive factories, predictable part runs, and deep pockets. But what happens when a small, high-mix shop decides to challenge every one of those assumptions—and wins? In this episode of Lights Out, we sit down with Katie Murphy from Arcamed, an 80-person medical manufacturing company that did what most shops think is impossible: they built a fully functional, high-mix automation system… themselves. No massive integrator contracts. No perfect production environment. Just curiosity, grit, and a willingness to figure it out as they went. Katie walks us through how their team tackled one of the toughest use cases for automation—low volume, constantly changing parts—and still managed to unlock serious gains in machine utilization, throughput, and employee growth. From a "hokey bookshelf" prototype to a system capable of running 50+ hours unattended, this is a masterclass in progress over perfection. But this isn't just a story about robots. It's about mindset. It's about rethinking what your people should be doing, where your real bottlenecks are, and how much hidden capacity is sitting idle in your shop right now. The result? More output, higher wages, and a team that's more engaged than ever. If you've ever said, "automation won't work here," this episode might just change your mind.
