The thing is that i need to make a remote control with atleast 13 buttons on it for making a robot that moves and got an arm on it
i need to know should i buy pic (model not important)
or should i get the arduino uno rev 3 with 2 atmega's
i want to use microcontrollers because there isn't an encoder/decoder more than 8 bit

Yes, you can. Here is a link using PIC as encoder and decoder using the Philips RC5 protocol.

Without using PIC, you can address more than 8 channels per transmitter/receiver. Using PT2262 encoder as an example. It has 6 Address/Data lines and 6 Address lines. The 6 A/D lines can be used as Address lines or Data lines. When used as Address lines, you'll have a single channel of 12 bit Address remote. But if you used it as Data Lines. The D0-D5 can address 64 channels per receiver but with a fixed Address at A6-A11.

Study the datasheet attached and understand it well so you can make full use of it.
