The LEGO Group have advertised the EV3's excellent backwards compatibility with NXT. As the cables are the same, the EV3 will work with NXT sensors, motors and, of course, LEGO Technic bricks. RCX sensors will work with the aid of converter cables. Software designed for programming the NXT will not work for the EV3 as the NXT runs firmware, but the EV3 ...

From the official EV3 FAQ: What does EV3 stand for? This is the third generation of the LEGO MINDSTORMS platform and the "EV" stands for evolution, hence EV3.

If you purchased the educational version, which presumably you did given the retail one isn't out yet, then, yes, the software is an additional purchase.

As you say, there are still tons of unknown at this point, so asking the question is way premature. However, considering the software is said to be based on the same technology as the one in the NXT, it's likely it won't be too different, and that's why that software will be able to control NXT bricks. However, I also doubt you'll be able to control EV3 ...

The graphical software that ships with the EV3 set can program both EV3 bricks and older generation bricks. We assume that this means NXT 1.0 and 2.0 bricks. However, it is unlikely that NXT-G will work with EV3 bricks as EV3 bricks run a custom build of Linux, whereas older bricks run a custom firmware. LEGO will create an offical app for both Apple and ...

The Mindstorms EV3 brick uses Bluetooth 2.1EDR. What protocol they use on top of that is still unknown, but will probably be released publicly by LEGO at some point. It's likely some compatibility with the NXT is possible (that is, an EV3 and a NXT bricks should be able to communicate together), but this is pure speculation and I doubt they just reuse the ...

The color sensor works pretty well as long as the object is about 1 1/2- 2 modules from the object. The sensing is best when the object is flat. The object is large enough to be fully contained within the "spotlight" that the sensor emits. As long as this is true, it doesn't really matter what the background color is. Another thing to consider is that ...

NiMH batteries only provide 1.2V per cell whereas Alkaline batteries provide 1.5V (nominal values). This means that new/fully charged batteries will provide a total of 9V for Alkaline and 7.2V for NiMH. The EV3 is programmed to show low battery somewhere around 6.2V and turn itself off around 5.5V. There is no option a available to tell the EV3 the ...

Yes, it is possible to pass the port number as a parameter to a sensor or motor block via data wire. It's just that it's manually selected by default. To change this, go to the port of the sensor or motor block, and select the top-most option which has the plug icon on it: It will then create a data port for which motor port you want to use: The same ...

I could not find this in the help file, but according to this thread "Another little known characteristic of MyBlocks is that they aren't re-entrant. No two copies of the same MyBlock can be running at the same time." I tried a few simple programs in EV3-G and confirmed that this is true. The order in which they run appears to be random.

The EV3 will run old sensors, motors, and lego bricks. I am sure it will run NXT 2.0 and NXT 1.0 motors, sensors, and etc. but not sure for RCX.

The EV3 software (for home use) is available on: http://www.lego.com/en-us/mindstorms/downloads/software/ddsoftwaredownload/

That depends on which version of the Education Software you purchased: LEGO® MINDSTORMS® Education EV3 Software Single UserAs the name implies, this is only allowed to be installed on a single computer: "The single license version of the EV3 Software allows you to install and run the software on one computer." LEGO® MINDSTORMS® Education EV3 Software Site ...

I tried Lejos and removing the SD card and rebooting was enough to go back to original firmware.

EV3 has no support for the Light Sensor, just the Color sensor. There is a Raw Sensor that can be used to create a Light Sensor MyBlock. That MyBlock can then be used to create the various WaitFor, Loop, and Switch blocks using the Logic form of those blocks. Then there is the calibration problem. The Color Sensor block in calibration mode does not work ...

You can turn parts of your program into custom blocks by selecting them and choosing Tools -> My Block Builder from the menu. See https://www.youtube.com/watch?v=CApCoGQJRcU for a tutorial on this feature.

Instead of using the datalog block from education version, you can create a custom version using the file access block. It's a bit more difficult, but more flexible... You won't be able to directly use EV3 datalog management, but you can structure the file to be directly compatible with csv format, readable by spreadsheet programs.

You have two options. You can use an accelerometer. Lego sells one that can be found here. There are also aftermarket ones at mindsensors.com. This allows you to independently measure the acceleration of the robot. You have to then integrate this information twice to get positional change. The way to do this is to put it in your control loop and sum up ...

It looks like you have discovered a bug. You should report it using Help > Give Feedback. For working around the problem, the only thing I know to do is to cut the blocks with the black wires and then paste them back in. This seems to get rid of the black wires.

The .ev3 file is actually just a zip file. You can use any zip utility to browse the contents or unzip it. It will look something like this: ├── Activity.x3a ├── ActivityAssets.laz ├── Program.ev3p ├── Project.lvprojx ├── ___CopyrightYear └── ___ProjectTitle The ___* files are just plain text files, ActivityAssets.laz is another zip file and the rest are ...

First of all, let's identify the parts you are trying to attach. The EV3 medium motor is a pretty accurate description, I'll assume it means this. The linear actuator is more ambiguous, it can mean both the smaller and the larger variant. For the smaller one, I'd use two 3 x 3 technic beams or two technic triangles, one on each side of the motor, attached ...

I'm teaching an after school robotics program and the kids are using the LEGO MindStorms Education Core Set #45544. I was dealing with the same situation when I had to connect 10 EV3s to Bluetooth or Wi-Fi and I couldn't distinguish from one EV3 to the next. Anyhow, I figured out how easy it was to give each brick it's own unique identifying name. You want ...

For most of the screens, you can find detailed descriptions in the Users Guide found on LEGO MINDSTORMS download page. Additionally, there is some information in the help file of the EV3 programming software. The best resource I have come across that shows "everything", though, is the Apps > General Information: Userinterface section of the documentation ...

EV3 software will not download firmware to the NXT brick. For that you need the NXT-G software and a downloaded firmware file from Lego. 1.31 is the latest version. So if you're running EV3 on NXT, you shouldn't throw out the NXT-G software. Once in a while, it's still needed.

The home edition software will be a free download available from LEGO's website as of September 1st. It will include programming for the ultrasonic and gyro sensors and will be compatible withe the education version of the EV3 brick.

I needed to update the firmware. 1.05 was too old. 1.31 works. Download from: http://mindstorms.lego.com/en-us/support/files/default.aspx#Firmware I did need to run the old NXT-G software to download the newer firmware. I did not try to download the firmware using EV3.

As per This LEGO education FAQ, it is not possible to use the USB cable the same way it's done between multiple EV3 bricks: Can I connect my NXT Intelligent Brick to the LEGO MINDSTORMS Education EV3 Intelligent Brick? No. It is not possible to daisy chain with the NXT brick. However, keep in mind this is valid within the scope of official software; ...

In EV3, use a negative number for the power to go backwards.
