Today we have a guest blog post by DamonMM2000 on his new creation, the CUB3:
"Hello everyone!
To those who are reading this, I am DamonMM2000, and I have been building LEGO MINDSTORMS robots ever since the EV3 first came out in LEGO stores.
This is my newest build, the CUB3, inspired by gerardhogenhout's Lego Technic CUBE- or not only a CUBE?. Built with LEGO MINDSTORMS and Technic components, it includes 2 EV3 Large Motors, 1 EV3 Medium Motor, 1 EV3 Infrared Sensor, 2 small linear-actuators, a pair of hidden caterpillar tracks, and more!
With its insignificantly-looking cubic structure, CUB3 is engineered to look like your ordinary box just lying around. With the small linear actuators grounded, the body shell of CUB3 rests at ground level. A small open area at the top rear allows the Infrared Beacon/Remote to infiltrate to the Infrared Receiver hidden under the body shell. On smooth, hard surfaces, CUB3 is able to drive and move around its surroundings; what's more cool than an ordinary-looking (cardboard? you get the idea) box moving around your room? Carpet? Raised elevation? Obstructing obstacle? No problem for CUB3! CUB3 just runs the Medium Motor and extends the linear actuators, which in turn raises the body shell about an inch off the ground. The drivetrain is geared up 3:5 for extra speed!"

COPA-DATA zenon Challenge 2014

I came across this amazing challenge from COPA-DATA's zenon Visualization/Automation Software called the COPA-DATA zenon Challenge 2014
Meet Dimitri, He is a teacher at VIVES Technical College in Belgium, him and his students have participated in this challenge with an absolutely beautiful LEGO MINDSTORMS EV3 robot.

"I am a teacher in a Belgium technical university and my class and me are participating in a EV3 Robot competition “the zenon challenge” where we have to make an EV3 robot and program and visualize it with an industrial visualization software package called zenon. Our team is doing very well, but now in the final days of the competition it seems that the public voting system will decide if we end at the first place or the second place." Dimi, the VIVES Automation Team.

VOTE HERE for the DELTA EV3  "The manipulator robot that is on a clear mission" and help them get FIRST place

I don't know about you but my vote for these guys was easy check out their team page

Philea (Rosetta Lander) landed today on a comet !

Today's world news is out of this world! A spacecraft started its flight 10 years ago on March 4-2004, on it way to the comet 67P/Churyumov-Gerasimenko. See the live stream here and LIVE here.

Four years ago (Friday, July 23, 2010) we made a movie about the functions of the lander, with the use of 24 thousand LEGO bricks we made a look-a-like landscape, to show how the lander is drilling into the soil.

Door alarm and sizometer

The French MINDSTORMS community is very productive lately. :)
Today we present another guest blog from France, by Matthieu Desfontaines on two of his creations:

The door alarm of the new Lego Mindstorms EV3 can detect it when somebody comes into your bedroom.
It works with a light sensor along with an ultraviolet sensor. It can be activated or disabled with a badge which you simply have to pass in front of the door lock ! It's really cool, like a real alarm !
The light sensor can detect it when the door is opened or closed ,while the ultraviolet sensor (which works with the remote controle or the badge ) can detect it when you pass the doorway. After activating the door alarm with the badge, every time somebody opens the door, the alarm rings to inform you. You have to disable it with the badge to stop it ringing. The alarm is very small but strong and it is hung on the handle of the door.

The “sizometer” in Lego Mindstorms EV3 can measure how tall are you in just a few seconds ! It works with a gyro sensor, an ultrasonic sensor and a touch sensor. It can estimate your height very quickly and easily. You have to follow the instructions written on the brick screen : 1­ calibrate on the floor ( gyro sensor ) 3­ search the horizontal position ( to get the best measure ) This invention is not very necessary but I think that doctors should use it to save time !

All instructions and programs are available on my website.   Thank for reading it !

Today we have a guest blog post by Clarence Rossant from France an his new robot that is equipped with a camera:

"VI3WBOT is a mobile robot which is equiped by a camera (a mindsensors NXTCam V4), a color sensor, a touch sensor and a gyro sensor. Using the NXTCam V4, it can reconize and catch a yellow ball of specific size, thanks to its colour and its form.
In my first programm, I just made a recognition using colour information, but the robot also detected other yellow objects (for example the bottle of the video)! The NXTCam V4 delineates a detected object by a bounding box and outputs the coordinates of the corners (x and y). With this information, one can calculate the area and the rough form of the object. In my program, I test the area and the shape of all the yellow objects, and the robot always chooses the good object (or nothing, if no object is a yellow ball ).
The NXTCam V4 is a complex sensor, so it outputs a lot of values per second, and these values vary very quickly. To solve this problem, I created a new filter that smooths the data. It works very well! Without this "DataFilter" mini-program, VI3WBOT cannot work properly.
VI3WBOT cannot work properly either if the ambiant light is too poor (for example, a yellow ball is acquired as if it were green in the dark). So when the program starts, the screen displays the minimum luminosity that it required as well as the current ambiant light.

In the future, I will use my NXTCamV4 to make new more complex robots, like humanoïds and autonomous animals, or other "deadly" creatures...Coming very soon"

MindBOARDS forum back online!

After some weeks of downtime the popular MindBOARDS forum is finally back online again!
It has moved to a new server and is now poised again to answer any of your questions related to MINDSTORMS.

For details, see this post at Botbench.

Movie time; Maker Fair NY, LEGOWORLD 2014

A lot has happened, in the last two months. If you are linked to The MINDSTORMS EV3 Facebook page, you already saw nice things, form the Maker fair NY, and LEGOWORLD in Utrecht (the Netherlands).
Here are some videos:

A robot shark at Maker fair NY., by Kyle.

Andy with his Minecraft CREEP3R

a LEGOMakerBot 3D printer by Will, it can print with 2 by 2 bricks, how cool is that!.

a cool, fun, GoPro robot by Benjamin

Bazmark with a nice overview and his R2D2.

LEGOWORLD 2014 Utrecht, the Netherlands, an overview

Anika made a nice shark

Victor made also a cool video:

And some pictures of taken at LEGOWORLD 2014. With about 82000 visitors, FLL, moonbots team dutch delta, and teachers of the Libanon college form Rotterdam trained over 700 kids (and some adults) on how to program a EV3 robot. Matthias brought a nice set of robots from his new upcoming German book, and Laurens had his robot form the EV3 discovery book on show. I also showed the police car made form the mindstorms laboratory book by Danielle. With a massive LEGO car, Harald showed that you can build 10 times as big as normal.

Remember #robotmak3r Kyle, the Kid with the Timmyton?

Well he came and visit me at the LEGO MINDSTORMS kiosk at the World Maker Faire in New York last month. He brought along his latest version of his Timmyton now at V5.5 ... WOW!

Meeting Kyle once again and trying out his robot in person was really cool. Kyle's work didn't go unnoticed, it's a really good model he designed.  Filippa, LEGO MINDSTORMS community manager took the time to interview Kyle and produced this great video: 

Read more about his cool projects, see pictures and download LDD and programs by visiting Builderdude35 profile on the LEGO MINDSTORMS Community page

Are you a #robotmak3r?
If any of you have some cool robots you want to share with the world let me know, reach out, email, comment, find me on FB or on any other social media, post your robots on the LEGO Community page or document your work on your own blog. I'll be happy to share your story as well ;)
