The 2024 4-H LEGO ROBOTIC CHALLENGE IS LIVE!

Check out the manuals below.

The Maryland State 4-H Robotics Challenges provide the opportunity for members to participate in an organized statewide robotics activity. Members in each county will form teams that will build robots to perform specific tasks. The county teams will then have the opportunity to compete at the Maryland State Fair. Each year, teams of youth can compete in one of two Robotics Challenges: the “Lego Robotics Challenge” and the “Robotics Engineering Challenge” (REC). Both divisions will have a Jr. Division (8-11), Intermediate Division (11-13), and a Senior Division (14-18). In addition, mixed-age teams will be allowed and will participate in the age division of the oldest member on the team.

State Fair Registration

There is a cost of $5 per youth to register and participate in the Maryland 4-H Robotics Contests. Registration is done via 4-H Online and is NOT done via the Maryland State Fair website. Youth can not register as individuals for the robotics contests but only as part of an established team whose club has already been charted and fully enrolled via 4-H Online, with at least 2 fully certified volunteers listed as the team’s leaders. Youth will need to choose the county their club meets in when registering, and teams will need to provide their local educator with a list of all youth participating on their team. If a club is fielding more than one team and has multiple teams competing per division (i.e., signified with A, B, C… or 1, 2, 3… or Jr, Intermediate, Sr…. etc.), then the youth lists will need to be broken down for each team when submitted to the county educator. 4-H volunteers can coach more than one team, but youth can only compete on one team at the Maryland State Fair robotics contest. For more information on registration for these events, please contact your local 4-H educator. Registration for these events closes on 4-H Online on July 31st

Maryland State 4-H Lego Challenge

The Maryland 4-H LEGO Robotics Challenge has 4-H members build robots using parts from the LEGO Mindstorms NXT, EV3, SPIKE Prime and/or RCX kits. The challenge is run on a 4’ X 4’ table where robots start in a home base area and then travel autonomously throughout the board, completing predetermined tasks. Robots are preprogrammed and score points as they complete tasks within a 2.5-minute time frame. Each team plays in multiple rounds, with their best robot game performance counting toward their final score.

The Maryland 4-H LEGO Robotics Challenge will also require the team to prepare a technical presentation for a panel of judges. In addition, the teams will demonstrate how their robot and attachments work, share their engineering notebook, and explain how they worked together throughout the season.

The community service project is a third component of the Maryland 4-H LEGO Robotics Challenge. Each season will present a new theme for the LEGO field and this project where teams will be asked to develop a service project that relates to such. The team will then prepare a visual presentation for a panel of judges explaining their service project and its impact on their communities.

The final overall score for each team will be a combination of their best robot round, their technical presentation score, and their service project score.

4-H Robotics Engineering Challenge

The Maryland 4-H Robotics Engineering Challenge (REC) will have 4-H members building larger, more complex robots up to 18” X 18” X 18” which will compete on a 12’ X 12’ playing field built from carpentry supplies. The robot can be constructed from a variety of robotic platforms, including, but not limited to, VEX, Tetrix, or LEGOs. The theme of the challenge will change every year and will integrate STEM topics relevant to careers and current priorities in the industrial & technological worlds. Each game lasts 2.5 minutes, with the first 30 seconds being where the robots will perform missions autonomously using code preprogrammed by the team. The final 2 minutes of each game will be driver-controlled (teleoperation) through wireless controllers. The team with the most points after the full 2.5 minutes wins the match.

REC Teams will also present their engineering notebook, which they started and maintained throughout the season, and be interviewed by a panel of judges in the technical round. Teams can also craft a custom presentation for the technical round if desired. Judges will ask questions and score the team based on information they shared during this round, including the robot’s construction, it's programming, the group’s overall teamwork, and their community service activities.

Healthy Living Spark Tank Examples and Illustrations

Physical Healthy Living Innovations

• When your 4-H club visits the local nursing home, you notice that many of the older residents have a hard time reading what type of medicine is in their various medicine bottles, so you develop a “Medicine Magnifier”. It’s a simple invention, but it will help so many people. The magnifier is a flexible plastic lens that you can lay over a medicine bottle label to magnify the text. The nursing home residents and so many others are so thankful for your invention.
• Your class took a field trip to NASA. Your tour guide shared the many challenges astronauts face when they are in outer space. One challenge that really struck you was how difficult it is to use the restroom without gravity to hold your body on the toilet seat. So you decide to design a self-cleansing human waste removal system for a spacesuit similar to the self-cleaning cat litter boxes you’ve seen advertised on television. NASA and the astronauts will be forever grateful. 

Emotional Healthy Living Innovations

• You are sad to see so many of your friends struggling emotionally. So you decide to create something that will help them cope with the stress and anxiety some of them wrestle with. You develop a coping strategy wheel and share it with them. They are so thankful for this new tool to help them cope with daily challenges.  
• You’ve noticed that kids at school are being mean to each other. So you decide to build upon the concept of painted rocks and begin a campaign to create “Kindness Rocks”, which can be painted and decorated in any manner, but they all will have a tip on how to show kindness. The rocks are a hit, and before you know it a “kindness rocks” club is flourishing at school.

Social Healthy Living Innovations

• Your 4-H club has been learning about healthy living. You were surprised to learn that so many kids today feel lonely since anyone can talk to anybody at any time with all of our social media tools and apps. You decide that kids will feel less alone if they are actually spending time with other people, instead of with their phones or computers. So you design an app that records how much time is spent on social media and reminds people to go outside and interact with the world and all the fascinating people in it.
• You have a friend that has been severely bullied at school. You decide to raise awareness of bullying by designing and distributing anti-bullying buttons. These are pins with anti-bullying messages. You work with your teachers and principal to develop incentives to encourage kids to purchase and wear the anti-bullying buttons.  

Financial Healthy Living Innovations

• You are taking a financial wellness class in school. In class, you learn that nearly 70% of Americans have less than $1000 in savings. So, for your class project, you decide to create an app to track spending, savings, and sharing (giving).  
• Your little sister thinks she can have anything she wants. She doesn’t understand that money is a limited resource. To help her, and other young kids understand this, you develop a fun activity to help kids clarify needs from wants.
