I want to use the propeller in a custom robot and I'm wondering what kind of buffering is needed for the propeller chip

Not sure what you mean by "buffering".

Do you mean voltage translator:

Depends what you're connecting to. If the device is compatible with 3.3v logic, nothing needed. If you have a 5v signal coming in, you can protect the Propeller IO pin with a 4.7K resistor.
