| | RCX Roverbot morphs to NXT
|

I brought in all our RCX pieces for this week's "Lego A.T.V. Droid" class. I figured the kids might want to create a tracked robot or two. I made one myself after several kids struggled to create a sturdy base. At the moment, I'm staring at my (...) (17 years ago, 18-Jul-07, to lugnet.robotics.nxt)

I am brand new to the NXT world but I would like to purchase the rechargeable battery. My question: Is the A/C adapter unique to the battery or can a train a/c adapter be used instead?
