Using a second processor on the robot and having it talk with the main Robot Controller isn't the hardest thing in the world but it's not trivial either. If you don't have someone on your team who is pretty familiar with embedded microcontrollers then it could be difficult. Also, debugging communications problems between the two processors without the right equipment can sometimes be a challenge. All of this leads me to my question: why do you think you need a second processor? It could be a great learning experience, but on the other hand if you don't have a specific need for it then you might just end up putting yourself through a unecessarily frustrating experience. Also, if you let us know why you need a second processor it will put us in a better position to recommend one to you.
As for our team, we have used a Motorola HC08 series microcontroller on our robot for the last 3 years. It's a pretty simple processor to design a circuit for and all the tools you need to program it are available for free.
