To make your LEGO MINDSTORMS EV3 robot move forward, you need to create a program in the EV3 Classroom software, add a "Move Forward" block, configure it, and then download it to the robot.
Here is a step-by-step guide based on the EV3 Classroom process:
Getting Started with EV3 Classroom
The process begins with preparing your programming environment.
Step 1: Open EV3 Classroom
Start by launching the LEGO MINDSTORMS EV3 Classroom application on your computer. This is the primary software used for programming EV3 robots.
Step 2: Create a New Program
Once the application is open, create a new project or program. This provides a blank canvas where you can build your robot's instructions using programming blocks.
Building the Forward Movement Program
The core of making the robot move forward involves selecting and configuring the appropriate programming block.
Step 3: Place Move Forward Block
Navigate to the Movement palette within the software. Drag and drop a Move Forward block onto your programming area. This block is specifically designed to control the robot's motors to drive straight.
Step 4: Change Rotations Value
The Move Forward block typically has parameters you can adjust, such as speed, duration, or distance. A common way to control how far the robot moves is by specifying the number of motor rotations or degrees. Click on the value next to the rotation icon within the block and change it to your desired number of rotations. For example, changing it to 1
will make the robot move forward approximately the distance covered by one full wheel rotation.
Step 5: Add Exit Block
After the Move Forward block, it's good practice to add an Exit block or ensure the program has a clear end point. While not always strictly necessary for simple programs, it helps define the program's sequence and ensures it terminates properly. This block can often be found in the Control or More palettes, depending on the software version.
Step 6: Rename Program
Give your program a descriptive name, such as "Move Forward 1 Rotation". This makes it easy to identify the program later when you need to download it or modify it. Save the program within the EV3 Classroom software.
Running the Program on the EV3 Brick
Once your program is created and configured, you need to transfer it to the EV3 Intelligent Brick (the robot's computer) and run it.
Step 7: Connect EV3 to Computer
Connect your EV3 Intelligent Brick to your computer. You can typically do this using a USB cable. Ensure the brick is turned on and the connection is recognized by the EV3 Classroom software.
Step 8: Download Program
Use the software's interface to download your renamed program to the connected EV3 brick. Look for a download button or menu option. Once downloaded, you can navigate the brick's menu to find and run the program you just transferred.
By following these steps, your EV3 robot, when the program is run, will execute the Move Forward command for the specified number of rotations.
