Department H, Division 861 - Robotics
This category involves many different aspects of Robotics. 4-H members will learn more about how robots are designed and developed as well as the mechanical and electronic elements of robots. Involvement in STEM Robotics give participants a first-hand experience in modern technology.
The name and county of each 4-H member should appear separately on the back of each board, poster or article and on the front cover of the notebooks so owner of the exhibit may be identified if the entry tag is separated from the exhibit.
Reports should be written using the scientific method whenever possible1. Hypothesis 2. Research 3. Experiment 4. Measure 5. Report or Redefine Hypothesis. (Background, the Question or hypothesis, what you plan to do and what you did, Method used and observations, Results: what you learned. All reports should be computer generated and enclosed in a clear plastic cover. The reports should be attached securely to the display.
Posters can be any size up to 28 inches x 22 inches when ready for display. Example: trifold posterboards are not 28 inches x 22 inches when fully open for display.
Team Entries: To qualify for entry at the Nebraska State Fair, team materials entered in robotics classes that are clearly the work of a team instead of an individual must have at least 50% of all team members enrolled in 4-H. Additionally, all enrolled 4-H members on the team should complete and attach an entry tag to the materials. A supplemental page documenting the individual contributions to the project should be included. The entry will be judged as a team, with all team members receiving the same ribbon placing.
Creating a video of your robot in action would be helpful for the judges but is not mandatory. Videos should be uploaded to a video streaming application and exhibitors should provide a hard copy QR code for viewing.
H861001 - Robotics Poster Create a poster (28 inches x 22 inches) communicating a robotics theme such as “Robot or Not,” “Pseudocode,” “Real World Robots,” “Careers in Robots” or “Autonomous Robotics,” “Precision Agriculture” or a robotic topic of interest to the 4-H member.
H861002 - Robotics Notebook Explore a robotics topic in-depth and present your findings in a notebook. Documentation should include any designs, research, notes, pseudocode, data tables or other evidence of the 4-H members learning experience. The 8.5 inches x 11 inches notebook should contain at least three pages. Topics could include a programming challenge, programming skill, calibration, sensor exploration, or any of the topics suggested in Class 1.
H861004 – Robotics/Careers Interview Interview someone who is working in the field of robotics and research the career in robotics. Interviews can either be written or in a multimedia format (CD/DVD) such as a short video uploaded to a cloud sharing service. Include a QR code with your project to allow for judging access. Multimedia reports should be between three to five minutes in length. Written interviews should be in a 8.5 inch x 11 inch notebook. Written reports should be three to five pages, double spaced, 12-point font, and 1” margins.
H861005 - Robotics Sensor Notebook Write scratch code which includes at least three sensor activity. Include the code written and explain the code function. Codes can be submitted as a multimedia format uploaded to a cloud sharing service. Include a QR code with your project to allow judging access. Multimedia presentations should be three to five minutes in length.
H861007 - Kit Labeled Robot (cannot be free programmed) and Notebook This class is intended for explorations of robotic components such as arms or vehicles OR educational kits marketed as robots that do not have the ability to be programmed to “sense, plan and act.” The exhibit should include a notebook with the robot the 4-H member has constructed. Included in the notebook should be (1) a description of what the robot does, (2) pictures of programs the robot can perform, (3) why they chose to build this particular form, and (4) how they problem solved any issues they might have had during building and programming. A picture story of assembly is recommended.
H861008 – 3D Printed Robotics Parts This class is intended for 4-H members to create parts through 3D printing, to help create their robot or aid the robot in completing a coded function. Project should include notebook describing the process used to create the project, describe the success of your designed piece (did it work), intended use of the product and the modifications made to the item.
*H861900 – Project Constructed from Lego Elements – The exhibit should include a project the youth has designed and constructed out of Lego elements, a description of what it does and an explanation of the basic structural and mechanical engineering concepts incorporated.
*H861901 - Robotics Video This class should be displayed in a notebook. The notebook should include a video clip on a CD/DVD or online streaming platform that demonstrates the robot performing the programmed function. Include your pseudo code and screenshots of the actual code with a written description of the icon/command functions.
*H861902 – Build a Robot (may use kit) Include a robot and notebook including the pseudocodes for at least one program you have written for the robot, the robots purpose, and any challenges or changes you would make in the robot design or programming.
