Which programming language should i use for my project? And question about PIC.

[kloong]

I will be doing my finalyear project next year. And I thought of building a robotic butler, i.e: a robot that can be summoned by the user with a click on the remote control to bring the food/drinks that are stored in it to the user.
I am hoping that the robot could trace and go to the signal source and avoid any obstacles on its way.
Which programming language and micro controller should i use for this?

And is it possible for one to use PIC by self-learning?

I would suggest either PIC or Atmel. They are both well supported and you can learn how to use them on your own. If your go with PIC then I would use MPLAB and with Atmel use AVR Studio 4.
