Android Controlled Wifi Car with camera...

I'm very new to Arduino (Like a week :cold_sweat: )

I want to make this spy car which can be controlled over wifi...
My plan was to have a blueooth shield and then use an android app to send letter to the arduino board which then power some motors.

this is similar to what want.... but it seems really complicated.... (excuse my stupidity)

Does wifi work the same way? Also will a Uno be adequate for this project? And which wifi shield? Will I be able to use the Android hotspot to connect to the car?

I would be very grateful if someone could spare the time to help me a bit.....
thanks in advance.....
