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.
Prosthetic limbs and other artificial body parts have come a long way in the last 10 to 20 years, and many on the market and under development today can restore nearly the same functions as the human body parts they’re replacing, or even improve them.
