How To: NASA Engineer Shows You How to Build a Mini Curiosity Mars Rover Out of LEGOs
You might have seen our post on this last week: It's a working reproduction of the Mars Curiosity Rover made with LEGOs, but it's a bit complicated for anyone without a decent amount of robotics knowledge. Plus, you need to have some Mindstorms NXT and TECHNIC parts lying around. If you want something a little simpler than programming a working LEGO rover, you could always build a scaled model of the MSL out of regular LEGOs. Not only is this easy to build and looks great, but the step-by-ste...
News: Autonomous, Solar-Powered Fijibot Only Lives to Survive Another Day
Aside from being completely adorable, Fijibot is a completely autonomous robot that automatically seeks out light sources to charge his solar-powered battery. He's built from a 1.5 liter Fiji water bottle, packed with an Arduino Uno, 6 volt solar panel, and an Arduino Proto Shield. His other parts are all off-the-shelf gear you could grab at RadioShack, while the wheels are from a discarded RC car. Fijibot isn't a particularly useful robot, but it's still fun to watch him navigate from light ...

News: Full-Sized Mechanical Skeeball Machine Built Entirely Out of K'Nex—And It Works!
