What can you recommend to start experimenting at home with robotics? Raspberry Pi?

No, no - I have a half a dozen RPi's of varying revisions. Since they run Linux and the SDcards are less than robust, anytime you accidentially trip the power (which to me happens several times during hardware debugging sessions) you risk scrambling the rootfs and thus need to reflash a new SDcard. Some SDcards get damaged. I recommend using Arduino and/or Wokwi (https://wokwi.com/ https://wokwi.com/) to get started.

I guess that depends on your software background. If C/C++ is not a problem, I would recommend Arduino. I found it simpler to just upload your program as the sole brain of your MCU, rather than working with a Raspberry Pi with Linux and all the abstractions, devices, etc that goes with it.

  Raspberry Pi will work with the Arduino environment as well.

  I’d recommend starting with this as well. The setup() and loop() model gets you started quickly and can take you through a lot of small projects before you want timers or other advanced features. Plenty of tutorials and libraries (often “working but not high-quality”) are available as well. Even if c/c++ scares you a little, I’d still start there (I came from a long c/c++ background, but I’ve seen my kids be able to do it with not nearly as much help as I expected to give them). Dirt cheap and readily available as well. Clones are fine; you don’t need the name brand Arduino boards.

Arduinos or Raspberry Pi's are both fine. I'd definitely pick up some motors and figure out how to do precision control. Lots of good info online for that. :)

Raspberry Pi, Teensy, Micro:BIT, ESP32, Arduino. Some steppers, some servos and some sensors. $200 will get you more gear than you'll be able to use in the first six months or so, it is incredible how cheap this stuff has become.
