I want to use a raspberry pi or arduino to create linear motion, back and fourth, my current goal is to make the pushing part for a baby rocker, but also a swing-rocker as a next project

I have looked at linear actuators, but they seem slow and very loud. Ideally I want something like this https://www.youtube.com/watch?v=qfmFS7nY2hU, but there is very little information on these and Im suspecting they are out of my price range anyway

The closest hobbyish Ive found is this https://www.youtube.com/watch?v=wHdFdw1hLzE or similar, but Id prefer a real product

Iv run out of things to google at "Magnetic Linear Motor", can anyone help me find a product that works with RPi or Arduino or at least a push forward,towards a quiet Linear motion with variable speed

  • \$\begingroup\$ The 1st is a linear motor with rod shape moving part, but the price of those are prohibitive. youtube.com/watch?v=0_QBl6-_jJU \$\endgroup\$ – Marko Buršič Aug 14 at 8:16

    \$\begingroup\$ A rotary motor driving a crank through a gearbox is probably the simplest option. That also produces harmonic motion, which is what you want for the applications cited. \$\endgroup\$ – henros Aug 14 at 8:30
  • \$\begingroup\$ @henros : are there any quiet motors? Ideally I want it in one (dev and tested by pros) unit. \$\endgroup\$ – Cowborg Aug 14 at 10:16
  • \$\begingroup\$ @Marko. Looks nice, I would like one of those. I think it would be to build somethibg like that myself. Di you know where to get one, preferrably hobbyist version. \$\endgroup\$ – Cowborg Aug 14 at 10:17
