This example shows you how to use Simulink Support Package for LEGO MINDSTORMS EV3 Hardware to run a Simulink® model on LEGO MINDSTORMS EV3 hardware. 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 and actuators. Additionally, the support package enables you to monitor and tune algorithms running on LEGO MINDSTORMS EV3 hardware from the same Simulink models from which you developed the algorithms.In this example you will learn how to create and run a simple Simulink model on LEGO MINDSTORMS EV3 hardware. See other examples for LEGO MINDSTORMS EV3 hardware to learn how to use External mode and to learn how to implement more complex algorithms.If you are new to Simulink, we recommend completing the Interactive Simulink Tutorial, reading the Getting Started section of the Simulink documentation and running the Simulink Getting Started example.
You will need the following hardware:LEGO MINDSTORMS EV3 BrickEV3 Wi-Fi Dongle or USB Ethernet Adaptor (Recommendation: Apple USB Ethernet Adapter)Verify the EV3 firmware version, and, if needed, perform a firmware update:1. Turn on EV3 brick2. Navigate EV3 screen to Settings > Brick Info.3. Verify that Brick FW is V1.03E or later3. If the firmware version is earlier than V1.03E, use the LEGO EV3 Software to update the firmware.There are four options to set up a connection between LEGO MINDSTORMS EV3 and your Host machine.1. Use the USB cable to connect the Mini-USB port on the EV3, labelled 'PC', and USB port on your host computer.1. Enable Bluetooth on your host computer. If it does not have built-in Bluetooth, use a Bluetooth dongle.2. In the EV3 Brick Interface, select Settings > Bluetooth and enable Bluetooth.3. Pair the host computer and EV3 brick.4. Navigate EV3 screen to Settings > Brick Info. Find the device ID of the brick under ID.Option 3: Wired network access1. Plug USB Ethernet Adaptor into EV3 Host USB Port2.
Connect USB Ethernet Adaptor to a network socket via an Ethernet cable4. Find the device ID of the brick under ID.5. Find the IP address under IP Address.Option 4: Wireless network access1. Plug EV3 Wi-Fi Dongle into EV3 Host USB Port2. Navigate EV3 screen to Settings > WiFi. Enable WiFi, search and connect to a WiFi network. See detailed instructions in EV3 USER GUIDE.3. Find the device ID of the brick under ID.4. Find the IP address under IP Address.For Wired and Wireless network access, perform the following test.In the MATLAB Command Window, enter h = legoev3(''). For example, h = legoev3('192.168.1.7'), to confirm the network connection between host machine and EV3 brick.Simulink Support Package for LEGO MINDSTORMS EV3 Hardware provides blocks that you can use to work with LEGO MINDSTORMS EV3 sensors and actuators.1. Enter simulink at the MATLAB® prompt. This opens the Simulink Library Browser.2. In the Simulink Library Browser, navigate to Simulink Support Package for LEGO MINDSTORMS EV3 Hardware.3.
Double-click the Button and Display block. Review each block mask, which contain a description of the block and parameters.In this task, you will create a simple Simulink model that detects the state of the left button on the EV3 brick and displays it on the EV3 brick LCD.1. In MATLAB, select HOME > New > Simulink Model.2. Drag the Button and Display blocks to the model. Use the default settings for both blocks.3. Connect the Button block to the Display block.In this task, you will configure and run your model on the LEGO MINDSTORMS EV3 hardware.1. In your Simulink model, click Tools > Run on Target Hardware > Prepare to Run... .2. In Configuration Parameters, set the Target hardware parameter to LEGO MINDSTORMS EV3.3. Update the Host to Target Connection parameters with the ones found in Task 2.5. In your Simulink model, click the Deploy to Hardware button on the toolbar. The model will now be deployed to the LEGO MINDSTORMS EV3 hardware.6. Look at the EV3 brick LCD while you press the left button.
The LCD displays the state of the left button, 0 for not pressed, 1 for pressed.A pre-configured model is included for your convenience. To change the IP address setting of the preconfigured model, click Tools > Run on Target Hardware > Options....There are two ways to stop the application running on EV3 brick.Option 1: Press the Back button on EV3 brick.Option 2: Enter a command in the MATLAB Command Window.Reuse variable h created in Task 2. For example, if your model name is ev3_gettingstarted, enter h.stopModel('ev3_gettingstarted').Run an existing model application on EV3 brick from MATLAB command line. nModel('ev3_gettingstarted')Delete a model application on EV3 brick from MATLAB command line. For example, run command h.deleteModel('ev3_gettingstarted')This example introduced the workflow for creating an algorithm in a Simulink model, and then running it on LEGO MINDSTORMS EV3 hardware. In this example you learned that:Simulink Support Package for LEGO MINDSTORMS EV3 Hardware provides blocks for configuring, reading and writing to LEGO MINDSTORMS EV3 sensors and actuators.
You can use the Deploy to Hardware button to run the model on LEGO MINDSTORMS EV3 hardware.Mysterious Stargate SG-1 And Terminator Faux LEGO Sets Turn Up In Sears Canada It seems that a company called Best-Lock is making knockoff Lego sets and has somehow acquired rights to Stargate SG-1 and Terminator Judgement Day. The proof lies in cheap building sets that have turned up on the website for Sears Canada. We’re not sure what the deal is at this point, but Best-Lock might be looking to corner the market on old franchises—possibly ones with a Canadian connection (as is the case with SG-1). Does this mean there could be a Spaceballs Best-Lock set floating around somewhere? One can only hope. Check out additional sets after the break.
