Lego Mindstorms used to automate tedious laboratory tasks

lego-bone-machines

Modern society owes so much to medical research, though what happens behind the scenes in a laboratory is usually far less than glamorous. A group of scientists at the University of Cambridge are working to develop synthetic bone tissue, but the process to create the samples used in the study is incredibly tedious.

To make the bones, a substructure must be dipped in a mixture of calcium and protein, rinsed, then dipped in a mixture of phosphate and protein…hundreds and hundreds of times. Equipment that can automate the process is available but very cost prohibitive, so the scientists did what they do best and built a set of robots to do the work for them.

Their new bone manufacturing setup was constructed using Lego Mindstorm kits, which were a perfect solution to their problem in several ways. The kits are relatively cheap, easy to construct, easy to program, and able to perform the same function precisely for days on end.

Now instead of burning time manually creating synthetic bone samples, the group can focus on the more important facets of their research.

Barrel organ made from Lego plays the Star Wars theme

lego-starwars-barrel-organ

Whether or not you are a fan of the first installment of the Star Wars prequels, you have to see what [Lorenz Lnggrtnr] and [Renee Hoffmeister] have put together for the movie’s 3D debut.

In an attempt to capture the essence of Star Wars in a new fashion, they constructed a large barrel organ from Lego bricks that plays the movie’s legendary opening theme when turned. The barrel is separated into four parts, each representing one of the series’ iconic settings in plastic block form.

Hoth, the Death Star, Tatooine, and Endor are all featured on the organ, with each environment’s structures playing specific notes from the song. As the barrel turns each Lego structure toggles a note to be played on the attached organ, via a “reading” mechanism built from metal arms and Lego tires.

It looks fantastic, and sounds pretty decent too. Be sure to stick around for a short video that shows off the barrel organ in action.

Water Strider robot does it with Lego parts

This Lego watercraft uses drinking bottles as pontoons arranged in a pattern that make it look very much like a Water Strider, the insects that dance on the surface of a lake.

After the break you can see a video of the rig gracefully navigating a local pond, along with a raft of ducks. It’s quiet enough not to startle them, which is nice. We don’t get a good look at the propulsion system, but [Vimal Patel] calls the floats “hockey bottles” in his Flickr comments. They appear to be Lego themed and we’re wondering if they are some type of packaging for a small set that doubles as a sports drinking bottle once the pieces are removed? The rig includes a camera which provides a great persepcive very near the water level.

This isn’t his only floating creation. He’s got a second rig that was used to film some of the footage of this one.

Working Tachikoma brings the manga to life

This Lego Tachikoma drives and walks just like in the TV program. You simply must take a peek at the video after the break. We’ve watched it several times and don’t think there’s any editing magic going on. But the movements are so intriguing part of us thinks there’s something fishy about it.

Each leg has a wheel that is connected to a motor via chain drive. But the little guy isn’t constrained to smooth hard surfaces. When the going gets rough, he struts his stuff like an eight-year-old crossing the lawn in roller skates.

This is not just for show and you can build it yourself if you like. The link at the top has assembly instructions. You will need several specialized parts though, not the lest of which is the cement mixer drum halves that make up the rounded blue chassis pieces.

Not sure what the heck this thing is? Don’t feel bad, you’d need to be a fan of Ghost in the Shell to recognize it.

Connecting toy blocks with a universal construction set

We were all children at one time, and surely some of us remember the pain of trying to make one type of building block work with another type of block. The folks at the Free Art and Technology Lab have an answer for your inner child: adapters that connect any type of building block to any other type of building block.

The project is called the Free Universal Construction Kit. This  “gee, I wish I thought of that ideas” is a set of 79 play set adapter that allow any child to mix up their Duplo, Fischertechnik, Gears! Gears! Gears, K’Nex, Krinkles, Lego, Lincoln Logs, Tinkertoy, ZomeTool, and Zoob building sets in any way imaginable. Most of these adapters are up on Thingiverse, ready to be printed out with a 3D printer or sent to Shapeways.

An interesting aspect of the work of the F.A.T. Lab is the legal and intellectual property aspect; since this is the product of reverse-engineering several building sets,  it’s entirely possible the manufactures of these toys wouldn’t want adapters out in the wild. The team really covered their bases, though. Of the ten toy systems included, eight are no longer patent protected, much to the chagrin of the company behind MEGA Bloks. Adapters for the  two remaining systems – Zoob and ZomeTool – won’t be released until the patents run out in 2016 and 2022, respectively.

Check out the video after the break for the wonderful ‘a-ha moment’ one of the inventors had when watching his 4-year-old son playing with Tinker Toys and K’Nex.
