Samsung S2 Or GTab2 + Ardunio (?)

Hello Forum!

I'm going to start a project soon where i build a robot that will be self sustained and totally independent of any human. However, I'm very curious if i somehow can use my Samsung S2 or Galaxy Tab 2.0 to compute all the data that the Arduino Leonardo originally will have to deal with.(?)

Anyone have any ideas/suggestions?

Many Thanks!
