Actuators are everywhere. Even outer space.
Outer space presents many exciting new challenges for actuators and automated control systems. Designing systems for hostile environments on earth is difficult enough, but bring the hostile surroundings of space into the mix and the difficulties become ten-fold. The need for applications that incorporate their use is increasing for many reasons, including the demand for more complex instrumentation; the actual size of space vehicles are becoming smaller; and they must be able to function in extreme conditions.
