Both sets include an EV3 intelligent brick. Hardware The Retail (Home) edition (set 31313) includes: 2 large motors, 1 small 1 touch, 1 color, 1 infrared proximity , 1 remote IR beacon The Education set includes: 2 large motors, 1 small 2 touch, 1 color, 1 Ultrasonic with red LED, 1 Gyro 1 rechargeable battery (battery charger sold separately) ...

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 ...

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.

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.

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 ...

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 ...

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.

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."

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.

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.

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.

Look at Tetrix or Matrix. Theese building systems have more porefull motors than NXT ones. Metal blocks allow you to create strong robots. Tetrix and Matrix robots can be controlled by NXT/EV3.

There are indeed two versions of the firmware to support the two sets of capabilities of the EV3 Brick, both currently at version 1.3/1.03: EV3 Firmware V1.03*H*.bin - The current "Home" edition. EV3 Firmware V1.03*E*.bin - The current "Education" edition. From what I've seen, you should be able to use either firmware on the bricks, however to get access ...

This can usually be achieved on the EV3 with a bootable SD card - you would set that up with a new firmware image and a loader that copies it across to the brick. The leJOS team have ported their codebase to the EV3 - so with a bootable SD card you can indeed load a modified version of the firmware onto your EV3 brick. You can then use their WiFi stack to ...

The math you're suggesting may work for going straight forward or backward where slipping is limited. For a turn, it will not come close. Even getting the center of rotation of the turning robot will be difficult. The tracks will have to slip. A tracked robot can not turn without those tracks slipping. Differences in friction will alter the turn. More ...

LEGO doesn't make a gyro sensor for NXT, but Hitechnic sells a gyro third party product and Mindsensors has a combo gyro/accelerometer/compass (IMU). Both can be used with EV3, and LEGO also has a gyro sensor, included in the Education kit

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 ...

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.

NXT Color Sensors are supported directly by EV3-G, the EV3 software running on the PC or MAC. NXT Light Sensors are not. To use Light sensors requires a bit of trickery. EV3-G has a Raw Sensor block that provides access to the Light sensor values. The raw sensor returns values from 0-1023, which is very different than the 0-100 of the NXT-G Light Sensor ...

You need to purchase the EV3 Education version of the software. It includes the EV3 Education version firmware. EV3 Education Software (single user licence) EV3 Software v1.1 Update (includes v1.06E firmware update)
