Do you need Arduino boards to program on Arduino.cc if so what should I buy. Specially with a ir remote
Are you referring to the online Arduino IDE (or web editor)?
With a suitable IR detector paired with the IR remote, you should be able to use any microcontroller to process and interpret the signals sent from the IR remote.
If you’re planning to control the Zumo 32U4 Robot using an IR remote, the Zumo 32U4 has three Vishay fixed-gain TSSP77038 IR receiver modules integrated into the front sensor board of the Zumo 32U4 Robot, which works with the Mini IR Remote Control. An example sketch (RemoteControl) is available in the Zumo 32U4 library GitHub repository under the “examples” folder to help get you started.
