Which microcontroller for making wireless bot?

Heyy, i want to make a wireless bot where it cuts the grass and also stores the path it moved in memory so for this purpose which microcontroller should i prefer?
also to control this bot what should i prefer either mobile app or game controller?
please help me through this.....

How will the 'bot' know and record its position, in the grass cutting area ?

How much experience do you have with Arduinos, motors, position recording etc ?

Sounds like and advanced project.

You hav a lot of other things to figure out before you choose a board.

can u elaborate what other things i need to figure out

earlier i did a project of grass cutting robot controlled over wifi but this time i need to memorize its path ,the way user moved it earlier it should store in it and later whenever wished just need to repeat its path movement with a single click

Do you have enough liability insurance, and a good lawyer. Those would be the first things to get.

Things like what sorts of sensors you will use, how the bot will record anything. You need to figure out what the chip has to do b fore you can choose a chip and know it's capable.
