Yeah. My first non-lego robot was almost identical to this and about as cheap. Although the esp32 wasn't out at the time and I used those cheap bluetooth serial modules. An interesting general purpose robot platform would support some kind actuator and charge itself. I'm also not convinced the integrated servo form factor motors with an external encoder is an improvement over a small stepper motor.
