I was able to finally create a plumbot, Thanks to you guys. I really appreciate the help.
But where do I get the crystals to create traitchips/nanites?

All around Oasis Landing. If you have the collection helper lifetime reward, you can set it to show crystal flowers, and if not, there's quite a few in the wastelands.

Or, you can buy them at the Bot Emporium, grow them like a plant, and talk to them to set the emotion you want each crystal to take on. This lets you get lots of crystals of all types reasonably quickly. And, if you follow BH's advice above, those crystals can also be planted and emotionally manipulated for your pleasure as well.

Or use TestingCheatsEnabled true and buyDebug then just place them from the plant spawners.
Edit: You could actually make a garden on a community lot (or your home) this way so you don't have to go to the future EVERYTIME.

^^Hell yeah, that way's the best if you're not opposed to a bit of cheating. Using buydebug for it means you can also pick what kind of emotionally charged crystal you want. Okay, so you'll still have to scream/hug/hump them every day so they keep their charge, but at least you don't have to fanny around starting them off on a certain charge.

Not that I'm lazy.
