Solve a Rubik’s Cube with just one EV3 set

David Gilday has published detailed building and programming instructions for a Rubik’s Cube solving robot that you can create with a single LEGO MINDSTORMS EV3 set. You can find the instructions for MindCub3r (here).

You’ll have to go through quite a few steps to make it work, but it’s probably still a lot easier than solving the cube on your own! BManCan1 has already followed these steps and he created this video:

EV3 Balancing Robot Program in Progress

Last night I started translating my my NXT-G balancing robot program to the LEGO EV3 software, and here’s some progress. I didn’t bother building a proper robot yet, but it works! This program should also work with Gyroboy – more on that later.

I’m using the HiTechnic Gyroscope for now, but I’ll add support for the LEGO Gyroscope, and I’ll also try to make it work with the Dexter Industries dIMU.

I’ll post the code to this blog when it’s ready, so stay tuned!

The Difference Between LEGO MINDSTORMS EV3 Home Edition (#31313) and LEGO MINDSTORMS Education EV3 (#45544)

This article covers the difference between the LEGO MINDSTORMS EV3 Home Edition and LEGO MINDSTORMS Education EV3 products. Other articles in the ‘difference between’ series:

* The difference and compatibility between EV3 and NXT (link)
* The difference between NXT Home Edition and NXT Education products (link)

One robotics platform, two targets

The LEGO MINDSTORMS EV3 robotics platform has been developed for two different target audiences. We have home users (children and hobbyists) and educational users (students and teachers). LEGO has designed a base set for each group, as well as several add on sets.

There isn’t a clear line between home users and educational users, though. It’s fine to use the Education set at home, and it’s fine to use the Home Edition set at school. This article aims to clarify the differences between the two product lines so you can decide which product works best for you.

LEGO MINDSTORMS EV3 Home Edition

The LEGO MINDSTORMS EV3 set (LEGO #31313) is the one you’ll find in toy stores and many online stores, as shown in Figure 1 (link). It is often referred to as the Home Edition or Retail Edition. Right out of the box you can build 5 robots including EV3RSTORM, GRIPP3R, TRACK3R, R3PTAR and SPIK3R (link) and 12 bonus models (link).

Figure 1: LEGO MINDSTORMS EV3 Home Edition (LEGO Catalog #31313)

You program the robot with software that you can download from the LEGO MINDSTORMS website for free (link). You can also control your robot with your smart phone, or with the infrared remote control that comes with the set.

The set contains 1 EV3 programmable brick, 2 Large Motors, 1 Medium motor, 1 Touch Sensor, 1 Color Sensor, 1 Infrared Sensor and an infrared remote, as shown in Figure 2. The set also includes 7 connector cables and a USB cable for programming.

You’ll need 6 AA batteries for the EV3 brick, and 2 AAA batteries for the remote. Instead of using 6 AA batteries, you can purchase the LEGO EV3 Rechargeable Battery and charger. (See “The EV3 Rechargeable Battery” below.)

The set further contains nearly 600 building elements, including beams, axles, gears and connectors, as shown in Figure 3. The inside of the cardboard packaging contains a mission pad (link). You can view an unboxing video of the set here (link).

Introducing: The LEGO MINDSTORMS EV3 Discovery Book

Published on October 30, 2013 by in Writing

A lot of you have been asking about my new book and rumors were spreading fast, but now it’s official! I’m working on a new book about EV3! It’s got everything you loved about the NXT 2.0 Discovery Book, and more. It comes with instructions for 7 completely new EV3 robots, complete hands-on coverage of the EV3 software, and over 100 building and programming challenges.

Best of all, the book will be in full color to make building and programming much easier!

I started working on this book more than a year ago, and it’s been a lot of fun creating new robots and writing about the EV3. Because we decided to print this book in full color, it’s going to take a while before it’s out (June 2014), but it will be worth the wait. You can pre-order the book from the publisher (Use coupon code DISCOVER to get 30% off!). Amazon is taking pre-orders as well. You’ll get more updates along the way, so stay tuned.

Here’s a short description:

The LEGO MINDSTORMS EV3 Discovery Book is a complete beginner’s guide to the EV3 kit from bestselling author and robotics expert Laurens Valk. This full color book teaches you fundamental programming and robotics skills as you build and program powerful robots that move, monitor sensors, and respond to their environments. You will build seven increasingly sophisticated robots like the BRICK SORT3R (a robot that sorts bricks by color and size), the THE SNATCH3R (an autonomous robotic arm), and LAVA R3X (a humanoid that walks and talks). Valk also covers more advanced programming techniques like data wires and variables, and shows you how to create custom remote control programs. More than 100 building and programming challenges throughout encourage you to think creatively and to apply what you’ve learned to invent your own robots.

Manty with Raspberry Pi and BrickPi

Remember the BrickPi Kickstarter campaign? It’s a shield from Dexter Industries that turns your Raspberry Pi into a LEGO compatible robot controller. The reward for my pledge came in a few weeks ago, and I’ve put it to use in one of my NXT robots: Manty.

Obviously, this robot works fine with the NXT, but now it can do everything that a Raspberry Pi can do. (Dexter Industries says they’ve developed the BrickPi for the classroom, but obviously they just wanted to build a six-legged walking xmbc media center which cleans the house and grabs drinks from the fridge on command).

LEGO MINDSTORMS EV3 Packaging Line

Here’s a video of the LEGO MINDSTORMS EV3 Packaging Line I posted about earlier. The machine collects elements for a small LEGO set called EV3MEG MINI and packs them in plastic bags, along with building instructions. The LEGO set is a scale model of the official EV3MEG bonus model.

Quite an impressive machine!

The machine is designed by Eric Steenstra, Martijn Boogaarts and Gerrit Bronsveld. They designed this huge automated warehouse a few years ago, so who knows what they’ll make next year!

LEGO MINDSTORMS at LEGOWORLD 2013

Published on October 18, 2013 by in EV3 News

These are some of the pictures I took at LEGOWORLD in Utrecht, the Netherlands before the entrance was open to visitors.

The setup is different this year, with more opportunities for kids to interact with the new EV3 system. I joined the crew of MCP and AFOLs to help demonstrate EV3 and answer (lots of!) questions from kids & parents. I’ll be back tomorrow on Saturday, so drop by to say hello!
