February 2012: The Tripod is built after the alien invaders of the War of the Worlds movie. Its unique way of walking allows this monster to walk straight in three directions, and can turn within its footprints. This robot can be built with the NXT 2.0 retail set 8547.
This Tripod ages back to 2009, since it was meant to be an official LEGO MINDSTORMS NXT 2.0 Bonus model. After a long delay, I decided to make it public on my own page. Download building instructions and NXC program from here. The program must be compiled and downloaded to the NXT brick using BricxCC, not the official LEGO NXT-G software. [wpdm_file id=12]
