you can use that old dongle but you will have to buy another dongle like bluesmirf for the mcu side of things.
two dongles will not do i don't think...

Thank James ,
I have 2 dongles but I saw in a video of axon that the builder connected an  dongle to the axon and another in the PC.
How can I connect my second dongle to the 50 $ robot.

now that is a more complex set up... he has the infra-red transmitting to the other axon the it transmits to the pc via a bluetooth... the way he has it wired i would say the one on the axon end wouldn't be a standard dongle on its own... i would think that it is a bluetooth module designed to connect directly to the uart...
so in your case i would say your best shot would be to look into uart-usb chips and see if interfacing the bluetooth dongle---usb-uart chip--uart port on mcu...
look into some of these things.
