A MOC TOWER CRANE

This Tower Crane is built mainly from bricks with holes.

The motors are the older 9 volt technic mini-motors. I used them

because it easier to connect them to bricks.

The crane is powered by a NXT brick; the demonstration

program on YouTube was written in NXT-G.

The crane in action can be seen on YouTube:
