Starting your STEM Journey: Running your First Program with the Virtual Robotics Toolkit

They say that you must walk before you can run, and much like taking your first steps, practice makes perfect. This is an age-old sentiment that’s true for running your first program with the Virtual Robotics Toolkit as well!

Complex programs are difficult to master right away, they may take hours of practice. That’s why this guide is intended to give you a starting point as you begin your coding journey. Without further ado, let’s teach you how to program your first simple program: a square path.

Programming a Square Path

When programming a square path, you may want to avoid the hassle of adding a long line of blocks, primarily because it will save time! This is where loops come in handy. Rather than your program looking like this…

….you could use a loop to simplify it and make your program look like this!

Let’s first look at some of the basics.

Basics of Programming

One of the basic programming blocks is the Move Steering block, which allows you to adjust the number of rotations, seconds, or degrees the robot’s wheels will turn for. It can be found in the Action Programming tab.

To begin programming a square path, attach a Move Steering block as the starting block. Before continuing to build your line of code, we suggest taking a quick read through the Move Steering Block article on LEGO’s EV3 Programming Guide.

Next, set the speed of this block to any value between 0 and +100, and set the number of rotations you’d like the wheels to perform. Don’t adjust the direction value, as you’ll want your robot to drive straight for the first leg of its journey.

Then, add an additional Move Steering block. It’s best to ensure that this second block is set to a smaller number of rotations (one rotation often works perfectly), because this will be the block that turns our robot into a different direction! If this block is set to more than one rotation, the robot will rotate too far and will not be able to achieve a tight turn.

Next, set this new block’s direction to either a sharp left turn or a sharp right turn. You can do this by adjusting the directional value, pictured below:

Your program should now look like this:

Drag the highlighted blocks into the loop you have already placed. It should look like this:

This program, by default, will repeat indefinitely. If you would like the program to repeat for a certain number of repetitions, seconds, etc., adjust the value in this column:

Connecting to the Virtual Brick

Before your robot can run the program you’ve just created, it must be connected to the LEGO EV3 Programming environment! This can be done in two simple steps.

1. Turn on the virtual brick by pressing the center button

2. Enable WIFI

Connect your virtual brick to WIFI by clicking the box underneath the WIFI icon. Doing this will allow your robot to run your program.

Running your Program

There are three ways to download and run your program in the simulation environment.

1. Click “Download and Run”

Once you have created a program and are ready to try it out, click the gray play button in the bottom right corner of the LEGO EV3 Programming environment. Clicking this button will automatically download and run the program in the simulated environment, it will just take a couple of seconds to work!

2. Using the EV3 Virtual Brick

If you prefer a more realistic programming experience and want to use the EV3 Virtual Brick to run your program, this option may be for you. First, click the downwards arrow icon in the bottom right corner of the LEGO EV3 Programming environment. Clicking this button will download your program to the virtual brick.

Next, navigate to the Virtual Robotics Toolkit window and click the centre button on the Virtual Brick. Note: If it’s not visible, pull up the EV3 Virtual Brick by clicking the EV3 button in Simple Mode (if you are in Advanced Mode, press F12 to change to Simple Mode).

Starting from Scratch – A Beginner’s Guide to the Virtual Robotics Toolkit

The Virtual Robotics Toolkit, with all its capabilities, can seem daunting at first! With so many options to choose from, how does one know where to start?

Hopefully by the time you’ve read through this short guide, you’ll have a basic understanding of how to use the software. We’re confident that you’ll love it just as much as we do!

The Basics

If you haven’t had a chance to check out our guide on downloading and installing the Virtual Robotics Toolkit, check that out first – click HERE!

Customizing the User Interface


In this view, the simulation environment is featured on the top, while the EV3 Programming environment can be seen on the bottom.

To start your first project, you’ll only need these two windows, but if you’ve purchased course content and need to log in, click the three-window button to open the Learning Environment. Move your cursor to the top of the screen to reveal the simple toolbar, then click the three-window button.

If you open up other windows in VRT while using the software, click the second-most right button on the top toolbar to return back to the default view.

Default view button

Fully Expanded

To fully expand the simulation environment window, click the VRT button, or maximize icon in the top right corner of its window. Doing this will hide the EV3 Programming environment.

Opening a New Project

The Simulation Projects window is divided into four tabs.

1. Sim Basics: A collection of beginner projects to get you started, including Sandbox, Apartment Cleanup, and Maze.

2. Competition Portal [COMING SOON]: A collection of advanced multi-player projects where you can test your newly learned skills against another friend or autonomous robot.

3. FIRST LEGO League: FIRST LEGO League’s 2016, 2017, 2018, and 2019 challenge mats (Animal Allies, HydroDynamics, IntoOrbit, City Shaper).

4. WRO (World Robot Olympiad):  World Robot Olympiad’s 2016, 2017, and 2019 challenge mats.

The first tab, “Sim Basics,” contains four projects to help you get started.

• Getting Started is nothing more than an empty room with a robot. In this distraction-free environment, you can learn the basics of starting and stopping the simulator, as well as how to use the keyboard controls to drive the robot.

• Maze helps you learn how to connect the MINDSTORMS® programming environment to the simulator. This will allow us to solve the maze by writing our own programs using MINDSTORMS® software and uploading it to the existing virtual robot in the simulator.

• Clean-up Challenge is the “build” challenge in this training series. While we can use the given robot to clear the playing surface, the real goal here is to introduce LEGO Digital Designer and demonstrate how we can use the LDraw import wizard to work with our own customized robots.

• Apartment is the last in the series of training projects. Here we can use the given robot along with its various attachments, and use our skills to program it to navigate around the room and vacuum the blocks littered on the floor.

The third tab, “FIRST LEGO League,” contains the following challenge mats:

• Animal Allies (2016)

• HydroDynamics (2017)

• IntoOrbit (2018)

• City Shaper (2019)

The fourth tab, “WRO,” contains the following challenges for 2016, 2017, 2018, and 2019:

• Recycling Plant, Waste Sorting, Clean Road to School (2016)

• Elementary Challenge, Junior High Challenge, High School Challenge (2017, 2018, & 2019)

Each project tile on the Welcome Screen is further divided into:

  • Preview – A preview video of the challenge.
  • Read More – A PDF built around that particular project file.

Click on the tiled image to launch the project and give your project a name.

The Learning Environment

The Learning Environment is the window located in the top right corner of your screen when you launch the Virtual Robotics Toolkit. It includes helpful resources that you can follow along with as you use our software.

You can access these resources directly from our online user manual or YouTube channel, or you can enter the details of a personal Microsoft account in the Learning Environment window.

Important: Users who choose to log in with a personal Microsoft account will need to email in order to register your account with the VRT Learning Environment.

Note: You don’t need the Learning Environment window (top right) to begin using VRT. You can also use VRT with a two-window display. Just press the two-window button (pictured) instead of the three-window button!

Starting & Stopping a Simulation

To start a simulation, all you have to do is press the play button. Once pressed, a green bar will appear along near the top of the screen, indicating that the simulation is active. When a simulation is active, your robot can be freely manipulated.

Simulation is not active (green bar not visible)

Simulation is active (green bar visible along the top of the screen)

When your program has finished running and your robot is no longer in the default starting position, press the stop button, , to reset the simulation. This will bring the robot back to it’s original position.

Driving with the Keyboard

We can only drive and program our robot when the simulator is running.
To turn the simulator “on”, press the Play button and begin driving the robot using the W, A, S, D keyboard keys.

As mentioned earlier, a green band will appear at the top of the screen to let you know that the simulator is “on”. As each key is pressed, it will become highlighted in the on-screen display, and the robot will move in the specified direction.

W = moves the robot forwards

A = turns the robot left

= moves the robot backwards

D = turns the robot right  

Connecting your Virtual Robot to the Programming Environment

It only takes two steps to connect your virtual robot to the LEGO EV3 Programming environment.

1. Turn on the virtual brick by pressing the center button

2. Enable WIFI

The EV3 Programming Environment

The Virtual Robotics Toolkit is designed to work with the EV3 Programming environment. If you are new to MINDSTORMS® programming, the language itself is quite different from traditional programming syntax. Unlike other languages, MINDSTORMS® robots are programmed by arranging sequences of modules to create new behaviors.

Mastering the LEGO EV3 Programming environment requires lots of experience and practice. To keep things simple, we won’t cover all of its details and features, but you’ll be able to self-study using LEGO’s own guide! Click here to access it.

You can also reference our own YouTube channel if you’d like some extra tips and tricks for navigating our software and the EV3 Programming environment! Click here to check it out.

Q: How did you first hear about the Virtual Robotics Toolkit?

I heard about the Virtual Robotics Toolkit through the World Robot Olympiad (WRO).

Q: What inspired you to get involved as a partner?

It was always a challenge to purchase robotics kits and make them available to schools. Part of my work involved training disadvantaged groups, and I saw that the high cost of the kits was a challenge.

The exporting and purchasing of robotics kits have been a great burden in Egypt since 2016, and from an engineering perspective, the use of a simulator is one of the essential engineering skills that we are thrilled to teach our students.

Last but not least, the Virtual Robot Toolkit fit perfectly within our pedagogy for the Ideasgym online platform we started.

Q: What do you think is the biggest challenge as an educator?

Linking the virtual environment to the real environment when using online technologies is a challenge that our team is working on every day. As our online teaching strategy is different than other MOOCs (Massive Open Online Courses), we are constantly researching to analyze and test our methods. Despite this, our greatest reward is the positive feedback we receive from our students, teachers and educators across the globe.

Q: What advice do you have for anyone considering the Virtual Robotics Toolkit as an educational tool?

VRT is a very good tool – it allows anyone to build a well structured curriculum around it. Prior experience with LEGO robots can be a great asset as it helps you use VRT efficiently.

Q: What are your plans for the future?

We are currently working to test and spread our pedagogy in different countries.
