How can I create a motorized turning mechanism for an automaton?

1 Upvotes

I build simple wooden automatons and I'd like a way to motorize the crank.

I'm attaching a gif of an example of an automaton (not mine, just a example taken from: Yam, CC BY-SA 4.0 https://creativecommons.org/licenses/by-sa/4.0, via Wikimedia Commons). To get the automaton to move, you need to turn the crank.

All my automatons have simple cranks made out of dowels. Different automatons require cranking at different speeds for best effect.

I can visualize a motor that turns a wheel at a set speed. And that wheel would have a hole it in that would fit the dowel. And the wheel would have to be the diameter that the crank reaches when turned a full rotation.

I know Lego has motors that can be developed into different items. The problem is, I have zero idea of how to produce such an item.

Would anyone be able to help me?

And just to clarify, I have absolutely no skill at figuring electrical things out, so in my ideal scenario, a wonderful person would walk me through the process step-by-step, as if I were 5 years old! And, I'd love a motor that could be plugged in, as opposed to being run on batteries.

Thank you in advance for any help!

I have one plate vertical space going up so I would like to know what pieces to use. I get that this might be too much so if its not possible that's fine.

Machine to turn on/off an electric shutter

2 Upvotes

Hi there,

How could I build a lego machine that I can mount to the wall in order to automatically open my shades in the morning?
I would like the machine to:

- Push the "up" button at a set time each morning,

- Then after a delay push the "down" button once in order to place the switch back to its initial position

I believe I would need a Raspery Pie to do so. But I don't have a clue on where to start, how to build the machine, where to buy the stuff, what to take into consideration etc. So any tips / help would be welcome!

Thanks
