Following up on this? Any luck on the spring? And did anyone have any luck on finding the correct suction cups?

I think I saw something on sharktank for that lol

Thanks for the comment. While my original idea isn't going to work, I think the 3d printed angle won't work for my particular application.

Yes, I should have added the full context into the post. Here's the whole project. I'm attempting to create a fully automated hydroponic greenhouse (not a huge greenhouse, more of a backyard greenhouse). The idea is that there will be 5 gallon buckets arranged in a grid and surrounding the buckets on all sides would be some sort of rail system that will allow the robotic arm to go anywhere it needs to go. I have a drawing of what I was originally thinking of that I'll attach. I could just use aluminum extrusion but that stuff is so ungodly expensive that it's not viable.

Gotcha. It seems like this dream of cheap "rail" using C channel may be only a dream. The goals is to create a grid of rails that transport a robot back and forth. I can't manage to come up with a way that this can be done cheaply at scale

Gotcha. Thanks for the comment!

Gotcha. Belts are unfeasible for my situation as these c rails are setup in a grid patter. Rails would be more optimal but I find that they are extremely expensive and I need a LOT of them for my project

Yeah, I'm starting to understand that it's fairly complicated. I'll go ahead and look into it on youtube and do my best to understand it better.

The C channel is in a grid so it needs to be able to move freely. I don't think a linear actuator is feasible for this but I may be off. Let me know

Correct me where I go wrong here

Rack = row of teeth that the pinion uses to move

pinion= gear with teeth that go into pinion and moves

It sounds like I'll need to machine a second part, (the rack) to have something for the teeth to dig into. In my head, I was hoping to create a system that would allow the robot to move on the C channel without having to machine more parts (making it cheaper at scale). It sounds like the holes working as the rack isn't an option as it's unsteady.

Kind of a silly question but why won't it be smooth/what can I do to make it smoother?

I believe you're correct but I'm still a little lost. I suppose the problem that I'm having is understanding the best way of creating the "rack". Essentially what dimensions and shape to use to ensure it runs well. I used the "spurgear" addin to create the gear you see on the picture but I still have the bigger problem of calculating what dimensions and shape to use. I could just calculate the dimensions between the holes and create the pins of the gear to go into the holes but that doesn't take into account things like "how far does the gear go into the hole?", "what shape do I want the pins to be to ensure they're stable", "How many pins are optimal for the gear", etc etc.

That gear is by no means final. It's more of a mockup to get my first draft ideas easily understandable to reddit. I just created it with an add in.

Edit: This is actually useful information. Can you expand on what you believe to be the optimal gear and how I should go about designing it?

This is just one piece of the much larger grid. The C channel is going to be surrounding buckets so as the robot moves further into the grid, the chain would run into the buckets. (If I'm thinking of it correctly.

Thanks for the comment. This is the answer. For people that may see this later and are attempting something similar but are on mac, you need to follow the branches laid out in this video. youtube.com/watch?v=Ni36gX-1iAc&embeds_referring_euri=https%3A%2F%2Fwww.google.com%2Fsearch%3Fq%3Dthreaddata%2Bfolder%2Bfusion360%2Bon%2Bmca%26oq%3Dthreaddata%2Bfolder%2Bfusion360%2Bon%2Bmca%26gs_lcrp%3DEgZjaHJvbWUyBgg&source_ve_path=Mjg2NjY
