The only predictive activity you can pursue is to take it to an EMC lab and run the full suite of radiated compatibility tests. You probably wont find any violations . . . and even if there are some, the probability of posing a risk is low.

What energy class are we talking about? Mounted on an ECB to stroke the Arduino parts? I wouldn't worry about it. Bob . . .

The servos need pulse modulated... a g ood application for the Arduino. The servos and Arduino need power at aroun d 5V thus the necessity for regulator.
