Details: Last time we featured JP Brown's work, we saw his Rubik's Cube Solver, which was conveniently hosted on his own site. This time though, LEGO® MINDSTORMS NXT-themed blog TheNXTStep brings us his new aquatic robot. This robot has some non-LEGO parts that float (I don't know what they are, exactly, but I am pretty sure it's technically "cheating" some astute commenters filled me in - these are zeppelin parts from the Adventures line (which was out about 8 years ago)), but and the programming and the moving parts are all done with MINDSTORMS parts. You can even see it steer itself with different rowing patterns in the YouTube video:
This is controlled remotely via bluetooth with a .NET program - which means that this isn't completely autonomous, but I suspect that the programming has simplified it to the point where not much is done manually either.
Oh, and DON'T TRY THIS AT HOME KIDS, it's NOT SAFE to risk your NXT by putting it too close to the water. If you are going to try to create something like this yourself, make sure that you can test the non-electronic parts first in a smaller body of water (maybe a full sink or tub) so that you can make sure that the expensive electronic parts will be safe and dry.
Details: Here's a great castle. There are some nice details, cleverly-designed chickens, amazing trees, a great entrance way made with several arc pieces - but the one that takes the cake is the way that a large amount of 1x2 bricks make up the walls. It probably hurts the stability of the model a bit, but it makes the wall look more like it was made out of regular-size bricks like real castles.
Details: In general, its not that difficult to build something small that looks like a spaceship. Technique is key in making a small ship stand out. This particular ship makes extensive use of a wide variety of TECHNIC components. A handful of bricks forms the top of the ship, but the rest of this is a delicious mix of unusual uses of parts - we have propellers stacked up with an unusual studless gearbox with a non-spinning gear configuration at one end, pneumatic splitters combine with Life On Mars arms to create a netted effect on the the front, the sides make great use of hollow tubing, and there are even goofy half-stud tricks used on the axles to give the impression of different inner sections of a spaceship.
Details: Here's another fun twist on LEGO® sculpture - this one makes use of some wire strings (mild cheating) and TECHNIC elements to provide complete functionality. It's a great-looking sculpture too, but the details of how it works just like any other harpsichord are amazing. Here are some details rom the link above about using unusual parts:
Some of the more whimsical LEGO elements were integrated as well: arches (and inverse arches) for the soundhole, roof slopes for the "curvature" of the internal frame and leg decorations, rubber tires to reduce the "clack" of the keys and jacks, and cloth capes (as worn by the likes of the Hermione Granger minifig) for the dampers.
Details: This model is a microscale reproduction of Star Ferry and one of its piers. There are some clever studs-not-on-top bits in here - and enough photos to give away most of it too. Good luck, though, finding enough tiles and clock faces for something like this - these models with almost no studs showing on the outside are not easy to make. (Thanks to the Brothers Brick for this one - they also dug up the link to the original Star Ferry)
Details: Here's another brilliant town building modeled after the Cafe Corner set. This one is a bit different though - it's a sort of avant-garde pizza shop in an old building with realistic colors. It can be tempting sometimes to make all houses out of brightly colored bricks - especially when the grey shades can be hard to find and properly match. The color of the walls wasn't actually the biggest hurdle for this model though - that would be the large amount of smooth tiles used on all of the floors and stairs. It's too bad, though, that this type of thing requires so many different specialized parts from different eras of the LEGO company - classic space computer panels are mixed in with newer dark green tiles and that's all on top of the old gray bricks. This is a beautiful model, and for the reasons mentioned above, it's probably one of the most ambitious layout-sized city models you'll ever see.
Details: With the slew of new parts coming out seemingly every season, there are truly never-ending possibilities if you keep your collection up-to-date. This model is one example of what you can do by coming up with another way of seeing the newest parts - the claws for this unusual crab are made out of those new skeleton-horse parts. There's only one picture of this one (making it a bit hard to figure out just how everything is connected), but there's a write-up that's very useful. See, if you look closely you can spot one 1x1 studs-not-on-top brick on the lower end of each horse - those 2 bricks are connected by a 1x6 smooth tile plate underneath. I'm not sure how sturdy this thing is, but this is one clever little model. Clever and scary - it is a skeleton crab, after all!
Details: So far I've mostly focused on hardware for Robotics Monday, but good LEGO® software is important too. The LEGO Group has been great about making drivers and such available so that programmers can easily create custom mindstorms based programs. This particular example is similar to the "Remote Control" that was released for the RCX a few years back, but this one makes use of LEGO® MINDSTORMS NXT's bluetooth capabilities to provide a bit more functionality and reliability. The link above has files you can download to add this functionality to your bluetooth-enabled device and even includes source code if you want to "build" your own.
Details: This series of detailed vignettes is a take-off on Disney's small world thing (whatever they call it at "Epcot"). What makes these great, though, is the way that microscale buildings and mosaic backgrounds are used to back up the international minifigs. There aren't too many pictures here, but they're all worth a close look.
Details: This detailed village model is a diorama of sorts showing a joust that might take place in medieval times. One nice feature that might not stick out at first is the way that this has been done on an extra large baseplate (15" x 15", for the Americans out there) - the gray color has been almost entirely covered with dozens of green bricks, which give the model a solid but grassy look in between the buildings. The buildings themselves are classy too - I love the way that arches have been used as window awnings here. The spectators here look a little squished, but otherwise this is an effective example of how to fit a large scene on a single baseplate.
