R2-D2 vs a battle droid

Who wins?

Location: Ilum cave

Positions:Two different ends of the cave.

1) Lightsabers: Battle droid. The lack of arms are R2's biggest disadvantage in this area.

2) Force: R2-D2. Obviously.

3) All-out: R2-D2. I think that if R2 uses enough smart tactics that he can outmaneuver him.
