Can arduino handle this much work?HELP-First time maker

I will make very small robot with wheels+ display + color sensor .Wheeles will be remote controlled and I need to manupilate info from color sensors and write it to display with stopwatch . For example robot goes and stands on brown surface and displays "You are on ..brown.. surface for ..10.. seconds  " or  when it reaches to 1 minute it displays "You are on ..brown.. surface for ..1. minute and you should leave  "

Questions -
1 -Can arduino handle this much work ? If yes which model should i prefer?
2 -Is  raspberry pi a better choice? Again if yes which model ?

Little note 
Coding wont be problem .I have worked with c languages.Im  just inexperienced with mechanical stuff.
I want my robot to be fast from all aspects( obviously) .
i might add some features like voice or camera in the future.

Yes of course, an Arduino UNO can do the trick without any problem.

What you need is a RGB sensor (e.g.TCS34725), LCD display , Bluetooth module like the HC-05, some 5V stepper motors with UNL2003 drivers for the wheels (or just use normal motors if you don't need to control the robot with high accuracy) .

However, if you are planning to add new features like voice or camera, Raspberry pi will be a better choice. Though, the modules mentioned above will still be usable with raspberry pi's GPIO pins.
