Robot Building & “Ah-Ha” Moments

The 3rd graders are now days into building their first Lego robots of the Robotics Unit. Michele, the 3rd grade Science teacher, and I decided to have the groups build different models so that we can have them compare and contrast the three designs later. It’s proving to be a learning experience for us too!

Sadly nothing is perfect and the only drawback is that these pre-made instructions use NXTs without the Lego rechargeable battery packs – which we prefer over using 6 AA batteries. Michele and I hope to modify their build instructions in the future to include the rechargeable battery packs, which are larger and actually change the dimensions of the NXTs… making some designs “unbuildable” unless the bigger, bulky battery pack is accounted for.
