Festo was new to me until recently so now I'm seeing exactly what you mean. It's sometimes hard to find designers who can execute on both technical engineering and cutting-edge design. I imagine this is a company to watch, and perhaps even that will set trends for future robotic design.
Ann, I agree with you on the potential cost of these systems which are very well done and with quality components. Some motion control companies target the theme parks and entertainment venues; this kind of technology would seem to fit into those markets (not necessarily the dragonfly) and I wouldn't be surprised if Festo has experience in that area.
Re applications, I find it interesting that what looks a lot like the flying robots designed for military purposes is instead a robot designed for industrial uses. These may seem like very different applications,. but they share a lot of functions--and thus features and technology--in common.
