 We produce gray and ductile iron castings. Automation is getting bigger and bigger throughout our entire company. A specific plant here in Wapaka was just introduced to robots. So we had a wide variety of maintenance and electrical folks that have never dealt with any of the robots before. So that's what that training was designed to do, was to kind of help them understand what was about to come. Fox Valley Tech has always been our number one stop shop, if you will. Tell them what we're looking for and what we need, and 99 out of 100 times, they'll put it together exactly as we need. The four-day class for robotics. I had been through one, probably a year ago, it was a two-day class, and this one here was an extension of that. They have all the equipment to use. They had to be 10, 12 robots, I think, little robots out there, and computers and all that. Before, we'd walk out there and go, I have no clue. But this addressed some of the troubleshooting issues, how to look through the programming, and how to scroll down and see what the robot's doing. They're specifically trying to teach us something that we can use out on the floor. Having these robots and having the guys have the knowledge that they have, has increased productivity. It's reduced the downtime, and believe it or not, it's improved safety, too. It makes my job a lot easier.
