I guess kids are a little more advanced these days, I was a kid of the '80s & '90s. Santa Claus had a habit of bringing me techy, educational-ish, toys from RadioShack. Remember RadioShack?
One of my favorite "robots," quite pedestrian by today's standards was the Armatron robot arm. Not even slightly programmable, so I guess not really a robot, but I learned a lot about motions, joints, and dexterity with that thing. Tortured a lot of my sister's Barbies too. Not sure if there's a modern equivalent, but there's quite a few on eBay.

I also had RadioShacks version of this thing, 100+ in 1 Electronic Playground. Really learned a lot about electronics from it, I remember making a really low power AM radio, and blowing my mind when it worked.

Of course Legos, tons of Legos, Constructs, and K'nex, I even had some battery powered stuff, cogs, gears, belts, maybe chains, again nothing programmable, not sure that was a thing yet.
Similarly I had a handful of Capsela sets. Anyone remember Capsela? Again, I don't think anything I had was programmable, but I had a few different things I could power, wheels, propellors, etc. Looks like there's still some vintage sets available.
It appears that Capsela lives again, as IQ Key, might be worth looking into.

None of that probably helped, but I thoroughly enjoyed that little trip down memory lane, so thanks.
