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.
