Updated 12 Sep 2018

Simulink® Support Package for LEGO® MINDSTORMS® EV3 Hardware enables you to create and run Simulink models on LEGO MINDSTORMS EV3 hardware. The support package includes a library of Simulink blocks for configuring and accessing LEGO MINDSTORMS EV3 sensors, actuators, and communication interfaces. It also enables you to interactively monitor and tune algorithms developed in Simulink as they run on the LEGO MINDSTORMS EV3.

This support package is functional for R2014a and beyond.

MATLAB R2018a is out!!

1. Measure data using LEGO EV3 blocks: You can now read data from the LEGO® MINDSTORMS® EV3 brick using these blocks
* Battery: Measures the voltage of the battery located in the EV3 brick.
* Timer: Measures the elapsed time from the time the EV3 brick starts running the Simulink® model.

2. Measure data using LEGO EV3 Compatible NXT Sensor blocks: You can now measure data from the LEGO NXT sensors connected to the LEGO MINDSTORMS EV3 brick using these blocks
* NXT Touch Sensor: Reads the state of the NXT touch sensor.
* NXT Ultrasonic Sensor: Measures the distance between the NXT ultrasonic sensor and the nearest object in front of the sensor.
* NXT Gyro Sensor: Measures the rate of rotation (yaw) along the single axis of the HiTechnic NXT gyro sensor.
* NXT Sound Sensor: Reads the sound level measured by the NXT sound sensor.

Hi Prof Perruquetti.
I created a Tech Support Case to investigate the compilation issue. One of our engineers will be in touch soon.

Hello I am using Matlab 2018a on a mac book pro (Mac OS High Sierra), I dowloaded and installed "Simulink® Support Package for LEGO® MINDSTORMS® EV3 Hardware". Then I open "ev3_drive_openloop" and then deploy to hardware.
I get the following message:

It seams that the cross compiler (probably part of the thirdpart) was not dowloaded and installed. I check if "usr/local/carlson-minot/crosscompilers/bin/arm-none-linux-gnueabi-gcc" does and exist and it was not the case. I tried to install it manually... but did not succeed. Can you provide me some help with this problem ? (I am Professor at Ecole Centrale and teaching control and robotics: thus I know that this package is working with release 2017b on windows for my students).
Thanks best regards

I am using MATLAB 2017b (on MacOS). After setting

the connection mode to bluetooth,
and the ev3 id I read on the brick,
when I try to deploy on target hardware the ev3_getting started demo, I get the following error :

### Build procedure for model: 'ev3_gettingstarted' aborted due to an error. The following error occurred during deployment to your hardware board: Instrument Control Toolbox is required for this functionality.

This toolbox is not in the requirements EV3 2017B reqs for the EV3 Support Package, therefore my question.

Edit : I was able to deploy using USB mode, without error wrt the ICT toolbox

@ Wendell Capili
Simulink Support Package for LEGO Mindstorms EV3 is supported on Mac starting from R2016a release.
Details can be found here : https://www.mathworks.com/hardware-support/system-requirements.html

Is there no version for macOS? I am installing but this is what I am getting:

Simulink Support Package for LEGO MINDSTORMS EV3 Hardware cannot be installed on this system.
It requires:

Base Product: Simulink
Host Platforms: Win32,Win64,Linux64

Marco Biroli

I take back what I previously said about the 2016a version. The 2017a is much more well rounded and solved nearly all the problems I had. It's great to see all the effort that went in this add-on in just a year ! Keep it up !

Marco Biroli

There is no way as of 2016a to read distance from an infrared sensor, furthermore it could note manage to retreive data while the program runs in external mode, but maybe i'm just not good with this yet

I always get the Message, when i try to install the package:

There was a problem installing the support package. To resolve this issue, contact Technical Support

I have MATLAB R2016b.

What is the Problem here?

Hi, I was trying to install the support file for my MATLAB, I own the 2014a release, but everytime I try I always get this error message:

"MATLAB Support Package for LEGO MINDSTORMS EV3 Hardware is not available for this release of MATLAB."

So, what I need to do? It is because I don't have the data acquisition toolbox?

I was trying to install the support file for MATLAB ( I already have the support package for Simulink). Here's the link:

http://www.mathworks.se/hardware-support/lego-mindstorms-ev3-matlab.html

However, I got this error:
The file you are trying to view is not in a published state.

How can I get this support package ? And do I need it if I already have the Simulink support package ?

Is there a way to get this to work on Mac platform as I get an error

Brian McKay

@J S: Sorry, but the Simulink Support Package for Lego MINDSTORMS EV3 Hardware is only available for release R2014a onwards; there is no support package for R2013b and older releases.

J S

how should i install it in 2013b version?
(my school haven't got the latest vertion yet)
