What do you think of Festo's air muscle system, or air muscles in general? I don't work in the field, so my opinions are that of a layman, but I've been impressed with what I've seen in their videos.
Festo has a good product with its pneumatic muscles, but the same problems apply to them as it does to fluidic types. Complexity and the trade offs with force, frequency and range of motion.
I suspect the Festo muscles will end up in mostly industrial products which need simple, linear motion, and weight and efficiency don’t matter as much. Eg manufacturing equipment and active vibration damping systems.
