I want to make a robot beep in certain situations

Do you know what the part which will do the beeping is called? (Then I'll find how to connect it myself no worries)

Hi,

Several options for beeping really; loudspeaker, piezo buzzer, piezo disc etc. Some just needs a supply voltage to beep, other types need an oscillator to drive them.

A rather fast and fairly heavy robot with quite large wheels needs what? A lot of power?
Please remember...

Does a buzzer work by supplying voltage?

I just want something like: I pass a 1 and it beeps. Is it possible? Nothing too complex, just to add some fun to it, you know?

Yes you can do this very easily. you could try connecting the buzzers positive lead to the output of the MCU and the negative lead to the negative, then send a HIGH signal to the pin for a certain amount of time.

example in pseudo code:
output_HIGH;
delay_500ms;
output_LOW;

Hopefully that is what you wanted. :)
