Missouri 4-H STEM Extravaganza

Missouri 4-H STEM Extravaganza

April 18, 2020 at Show Me Mizzou Day


The Missouri 4-H STEM Extravaganza will allow 4-H members in the Robotics and Computer Science projects an opportunity to showcase the skills they have gained in teamwork, engineering, programming, and problem solving. There will be a few contests: Autonomous tennis Ball Collector (AtBC), Robot Exhibition, Scratch Google Doodle, and STEM Projects Exhibition. Robot platforms include Lego Mindstorms, VEX IQ/EDR/V5, or any other appropriate robot meeting the requirements of the challenges. Interviews are part of the challenges. Participants may also have an educational display and/or demonstration. Each individual and/or team will have a pit area to collaborate, program, and maintain robots as necessary.

This event is sponsored by Missouri 4-H and MFA Incorporated.


Registration is open March 1 through 4HOnline and will close on April 10. The challenge is open to Missouri 4-H members. There is no requirement to qualify at a local robotics event.

This is an individual or team challenge: youth may be part of a team of 2-5 youth in the same age division. There is a participant fee of $10 per youth; with $5 entry fee per youth per challenge entered. Credit Card payment preferred with cash or check payments made to the county of 4-H enrollment.

Registration is available through 4HOnline.

Youth will register individually and will compete as individuals or on a team in the same age division. They will identify the team members when they register (each youth will do this.) Team members must be in the same age division. Participants must be 4-H age of 8-18 as of January 1, 2020. Age divisions: junior (8-10), intermediate (11-13), and senior (14-18).

Overview of Challenges

    Autonomous tennis Ball Collector (AtBC)

    Date TBD as part of Show Me Mizzou Day

    Open to all age divisions

    Your mission is to develop an autonomous robot that will collect tennis balls on Tennis Court Table and put them into a Ball Box. Points are earned based on number of balls in the box, inside the Box Fence, on the robot, or outside the Tennis Court Table. Additional points will be earned if Trash Bottles are moved completely off the Tables. All the tasks should be done completely autonomously within 2 minutes without any external help. The procedure on how to end a Game is unveiled on the competition day. Any robot kits may be used.

    Additional resources to help with the challenge and programming can be found at the robofest.net website.

    A video workshop, Powerpoint slides, and examples for coding can be found under Lego EV3 Game Workshop Materials or Robot Mesh Studio Software & Workshop Materials for the 2018 Spring.

    Scratch Google Doodle Contest

    Open to all age divisions

    As part of the Computer Science Pathways grant to Missouri 4-H, there will be a virtual contest to create a Google Doodle using Scratch. This is open to each age division. Creations will be uploaded for judging and displayed during the contest day. The project entries may be created by individuals or teams. Youth entering the Google Doodle Scratch Contest do not have to be present at the contest.

    Robot Exhibition

    Open to all age divisions

    In this event, youth are encouraged to be creative and present a unique robot exhibit or challenge for display. The robots must include an autonomous aspect and projects which interact with humans are encouraged. Use of a remote control for part of the demonstration is allowed, as long as the youth includes some programming of the controller beyond the basic tank or arcade driver controls and as long as they are able to explain their programming to the judges. Each robot exhibit will be judged for creativity and technical content. Youth who are brand new to robotics, as well as experienced youth, are welcome to show off their robot and field designs.
