 Um, so that's how it began. So we traveled around and, uh, we decided that a robotic inspection system would be the way to go, but we'll start simple. Can we even enter and drive to the end of the gate at first? And then second part of the project would be, can we inspect the gate itself? But there's a lot of value to just look at the conduit, look at the, uh, the tunnel and drive all the way to the end without humans having to do that.
