If you want to do what NASA just did, except in Lego form, then look no further. NXT builders Doug Moran and Will Gorman put together this amazing working Curiosity rover that can happily roll around plastic terrains, searching for the answer to Bowie's questions. Four of the six wheels are powered, enabling the gear to make 360 degree turns, while a fully working arm and mast are controlled separately. Of course, nothing we can say could compare to seeing it in the
flesh plastic, so head on past the break to see it in action.
