Noiseless actuators

I finally manage to find a way to make actuators that are enough powerful, small and the most important, noiseless. Since this robot will move all day long, it is essential not to hear it. I tried three types of motors: servos, DCs and steppers. It is not a secret for everyone, theses servos are terribly noisy. The gearbox of miniature DC motor I tried next is too noisy too. At last, I ordered a small stepper with a gearbox and it will be the one selected for the task. So I will replace the three servo motors with these steppers connected to a threaded rod that will move the swash plate.

I’ll have to 3D print some parts to fit all this together, but the essence is there. Now I have to learn to CAD.

There are the two motors, the stepper and the small geared DC one
