Rather than watching videos or reading on the internet, I think its worth it to get your hands dirty.

For starter, I always recommend a RC car with an Arduino (or cheaper equivalents).

Following can be had for less than <$100

- SG90 servo motor - 28BYJ-48 stepper motor - ULN2003 driver board - UNO R3 Controller Board (Elegoo) - RC car chasis/3D printed chasis

Hack around, add sensors, cameras etc. Next would be to build a robotic arm.
