  • Robosoccer Robosoccer

    Get creative with the design of your robot in Robosoccer!

  • Seek

    Discover new hands-on builds and

    programming opportunities to further

    your understanding of a subject matter.

  • The Completed Look of the Build

    Completed VEX V5 Speedbot

    This robot is designed so that it can be built quickly and driven around either autonomously

    or with the V5 Controller.

  • Parts Needed

    Can be built with:

    VEX V5 Classroom Starter Kit 

    https://www.vexrobotics.com/vexedr/products/v5-kits/276-7010.html

  • Build Instructions

  • The green icon indicates that the build needs to be flipped over (upside down).

  • Only one of the two sub-assemblies made in this step is used right now. The other will be used later in step 9.

  • Make sure your Smart Motors are oriented in the correct direction (screw holes facing the outside of the build and

    the shaft hole towards the inside).

  • Make sure your Smart Motors are oriented in the correct direction (screw holes facing the outside of the build and

    the shaft hole towards the inside).

  • The green icon indicates that the build needs to be rotated (180 degrees).

  • The blue call out shows what the orientation of the Robot Brain should be if the build were flipped right side up.

    Make sure the 3 wire ports on the Robot Brain are facing the V5 Radio!

  • The green call outs indicate which port on the Robot Brain to plug each device into using their respective cable.

    Build Instruction Tips

    Check the Appendix for info on how to use the new Hex Nut Retainers.

  • Exploration

    The VEX V5 Speedbot is meant to get you comfortable working with the system as quickly as

    possible. Now that the build is finished, explore and see what it can do. Then answer these

    questions in your engineering notebook.

    What types of activities could this build be used for in real-world situations? 

    What are the best features of this build? 

    If you were tasked with designing a new version of this build, what would you add or 

    remove from the build to improve its ability to push objects? Explain with details and

    sketches.

  • Play

    Test your build, observe how it functions,

    and fuel your logic and reasoning skills

    through imaginative, creative play.

  • Robot Soccer

    Robots playing soccer on a field

    Robot Soccer

    Engineers have built and programmed robots to play soccer for over two decades. Several

    organizations, such as the RoboCup Federation and FIRA, host tournaments where teams

    from around the world compete with soccer playing robots. What are some reasons that

    robot soccer is so popular?

    Two of the main reasons that robot soccer is so popular are:

    Entertainment – Soccer, or football, is one of the most popular sports in the world. Many 

    people enjoy watching and playing the sport. Substituting the human players for intelligent,

    responsive machines adds a fresh spin on the game.

    Research & Development – Robot soccer is an activity that requires multiple robots 

    working together to accomplish tasks (scoring goals and defending their goal), while

    reacting to another team of robots doing the same. Robot soccer is an incredibly creative

    and authentic setting for developing algorithms that allow robots to quickly track the

    trajectory of an object, take control and manipulate that object, and communicate their

  • position and other information to their teammates. All of these algorithms can be reused

    by robots in other environments to accomplish similar tasks.

  • Designing to Dribble

    Hardware/Software Required:

    Quantity Hardware/Other Items

    1 VEX V5 Classroom Starter Kit (with up-to-date firmware)

    3 Cones or cups

    1 V5 Controller 276-4820

    1 Stopwatch

    1 Soccer ball or similar sized ball

    1 Roll of tape

    1 Engineering Notebook

    1. Creating a Dribbling Course

    Dribbling course setup

    Set all three cones (or cups) in a straight line. Ensure there is enough space between each

    cone for the robot to fit through. Spacing cones farther apart will decrease the difficulty. Pick

  • a spot on the outside of the course (by one of the cones on an end) and use tape to make an

    "X" on the ground in that location. Place the soccer ball (or a similar sized ball) on the "X".

    2. Preparing Your Robot

    Power on the V5 Robot Brain, make sure it is paired with the V5 Controller, and run the Drive

    project on the V5 Robot Brain so that you’re able to wirelessly drive your robot with the

    controller.

  • 3. Dribbling Through the Course: Part 1

    VEX V5 Speedbot dribbling a soccer ball

    Position your robot next to the ball. No part of the robot should be touching the ball prior to

    starting. Your goal is to dribble (push) the ball between the first and second cones, and then

    between the second and third cones. After that, you need to dribble the ball around the third

    cone and make one more pass through the course by dribbling the ball through both sets of

    cones once more. Use a stopwatch to time how quickly you're able to complete the course.

    The stopwatch should be started when you first touch the ball with your robot. The stopwatch

    should be stopped once the ball has fully passed through the final set of cones on the

    second pass through the course. Run through the course multiple times to see how your time

    improves with practice. Record your results in your engineering notebook.

    Respond to the questions below in your engineering notebook:

    What was your best time through the course? 

    What strategies did you use to help improve your times? 

  • 4. Designing For a Purpose

    VEX Robotics Engineering Notebook

    Inside your engineering notebook, sketch some ideas for attachments that could be added to

    your VEX V5 Speedbot that would improve its ability to dribble the ball. Share your design

    ideas with others as you iterate on your designs.

    Keep in mind that you're developing this technology through creativity in order to make your

    robot better at playing soccer. Innovations in technology like this often start because of the

    need to make technologies better. There are many creative ways to make your robot better

    at soccer. Choose the ones that you think are your best.

    Respond to the questions below in your engineering notebook:

    What positive feedback did you receive on your designs? 

    What negative feedback from others did you receive on your designs? 

    What feedback did you incorporate into your designs? Explain how you did that. 

    Did sharing your designs with others help improve them? Why or why not? 

  • 5. Building Your Design

    Review your sketches and pick the one you believe will best improve your robot's ability to

    dribble the ball. Build the chosen design and attach it to your robot.

  • 6. Dribbling Through the Course: Part 2

    A Stopwatch

    Position your robot with your newly designed attachment on the X. No part of the robot

    should be touching the ball prior to starting. Using a stopwatch, dribble the ball through the

    course following the same path as you did in your earlier trials without the attachment. The

    stopwatch should be started when you first touch the ball with your robot. The stopwatch

    should be stopped once the ball has fully passed through the final set of cones on the

    second pass through the course.

    Respond to the questions below in your engineering notebook:

    Did your design help improve the time it took for you to complete the course? Why or why 

    not?

    What about your design could you change to further improve it? Explain how and why that 

    would improve it.

    Did you encounter anything unexpected when using your attachment? If so, what? 
