Hi everyone!
I’m making a degree project about robot localization system using Pololu 3pi as a development platform. Localization algorithm will probably use built-in 3pi IR sensors for detecting a floor grid and some ultrasonic devices to avoid wall collisions.
Here comes the important part: I want to be able to perform a localization algorithm on my robot and I want to be able to communicate with my robot using a PC. In order to achieve this, I think I should put heavy calculations on another microcontroller (master), connect it by serial with 3pi (slave) and a wireless transceiver (PC communication). I already have a 3pi and a wireless module, but I don’t know what kind of master uC I really need. Could you help me make my decision?

Some tips:
- Transceiver can be connected to master by UART (and maybe a voltage divider). So can Atmega328p from 3pi. That should mean a master uC needs to have at least 2 UARTs.
- I have a usbasp AVR programmer, so master uC should be able to work with it.
- Also, I would like to keep it cheap and simple.
Unfortunately that’s all I can say about the part I need.
Thanks in advance!!!
