LEGO Host For All Of Your Prototyping Projects

September 13, 2010 by Mike Szczys 7 Comments

[Deadbird] decided to use a LEGO 8880 Super Car as a host for all of his electronic tinkering. Throughout his blog (translated) you’ll find the vehicle with an Arduino MEGA interfacing various prototyping bits. It starts with the motors for locomotion, closely followed by a servo for steering. From there we see the addition of a breadboard and graphic LCD screen. So far he’s worked out the use of a PS2 keyboard as a controller and, most recently he’s interfaced a Wii Nunchuck.

We’re more used to seeing NXT kits adapted for wider use, but if you’ve got a nice kit like this one it makes a great base onto which you can add your own robotic elements.

CubeStormer; Quick Solutions From LEGO Parts

CubeStormer solves Rubik’s cubes and it does it quickly! Made entirely out of LEGO, a Mindstorm web camera is used to scan in the cube with four mechanical hands for manipulation. The device is capable of solving a random cube in less than 11 seconds. That’s quite a bit faster than the last Minstorm solver we saw, and the CuBear solver we are so fond of.

LEGO Hand Controller

June 12, 2010 by Mike Szczys 12 Comments

[David Hyman] built this device to control a LEGO claw. One one end of things is the part you wear, that measures movement of two fingers and your thumb. On the other end of things is a LEGO claw with three opposing digits. You move, it moves. The claw uses light sensors and a gradient strip for position feedback. There is also an up-down wrist action that uses a touch sensor as the input. This is impressive enough to give the sniper rifle a run for its money.

LEGO Printer Built Without NXT parts

[Squirrelfantasy] built a printer using LEGO pieces. It’s not a Mindstorm project but instead depends on some type of development board and some auxiliary components on a protoboard. We couldn’t get a good enough look to tell exactly what makes up the electronics so start the debate in the comments. We feel this is a printer and not a plotter because the stylus moves on just one plane while the paper feeds past it but that’s open for debate as well.

Guess this answers the question of why aren’t we building our own printers? Some folks are.

LEGO Pick And Place

Turn your volume down and take a look at the brick sorting robot in the video above. It’s built using LEGO and powered by four different NXT modules. It sorts differently colored bricks on the intake conveyor and places them on three output conveyors. The build is solid and was [Chris Shepherd’s] impetus for starting a blog. We appreciate the pneumatic tricks that he detailed in some of his earlier posts such as a compressor, pressure switch, and air tank system. His advice is “build, build, build” and that’s what you’d have to do to perfect a monster of this size and scope.

LEGO Gearbox – Seven Speed Plus Reverse

April 8, 2010 by Mike Szczys 44 Comments

We know LEGO is a very versatile medium to build with but this is beyond what we considered possible. Seven speeds and a reverse gear were built into the gearbox for this LEGO vehicle. It’s not completely an original design, but adds to the five-speed design found in a ten-year-old LEGO set. See it demonstrated in the video after the break. The design uses a sequential gearbox; shifting is accomplished by clicking the stick up or down depending on how you want to shift. If you’ve got enough parts on hand you can build this using the assembly photos that [Sheepo] posted.

Can’t get enough of the gears? Check out this model of a double clutch transmission.

LEGO Automatons

March 26, 2010 by Mike Szczys 47 Comments

Here’s a collection of little LEGO oddities. Some of them exhibit a purpose, such as this interesting take on a line-following robot. Others, like the four seen above, are just automatons built to bring a smile to your face through their motion. There are dozens to choose from, with several pictures and a video of each. See the clips of these four after the break. Oh, and don’t worry, we didn’t find any LEGO iPhone docks, just cleaver mobile creations.
