May 19, 2018

MizzouRec Complex

MU Campus, Columbia


The Missouri 4-H Robot Challenge will allow 4-H members in the robotics project an opportunity to showcase the skills they have gained in teamwork, engineering, programming, and problem solving. There are four contests: Unknown Challenge, Sumo Bots, Motorized Challenge, and Scratch Google Doodle. Robot platforms include Lego Mindstorms, VEX, or 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 April 10 through 4HOnline and will close on May 10. The challenge is open to Missouri 4-H members and do not have 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 through 4HOnline at

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, 2018. Age divisions: junior (8-10) intermediate (11-13) and senior (14-18).

Overview of Challenges

Sumo Bots: Open to all age divisions

A Sumo Bot contest involves two contestants/teams whose robots operate in the sumo ring according to the game rules. The individual contest continues until four Sumo points are scored by one of the contestants, or until one of the contestants has a score two point greater that an opponent. The overall contest is structured using a double elimination tournament format, where each robot must lose two matches to be eliminated from the tournament. Robot platforms can be LEGO Mindstorm NXT or EV3, Vex IQ or any other robotics platform that meets the size and design requirements.

Unknown Challenge: Open to Intermediate and Senior age divisions

Clubs will gather in the morning of the event for the Unknown Challenge Release, hearing for the first time details of the challenge(s) robots must accomplish. For 2.5 hours teams will work in their pit areas to design, build, and program two distinctly different robots that can complete the tasks outlined in the Challenge Release. At the end of this work time, clubs will demonstrate their engineering skills in the Challenge Events on the main stage in the 4-H Exhibits Building by completing the challenges. Robots must operate autonomously (no remote control.) Robot platforms can be LEGO Mindstorm NXT or EV3, Vex IQ or any other robotics platform that meets the size and design requirements.

Amusement Park Motorized Challenge: Open to Junior and Intermediate age divisions

Spinning - Twirling - Rising - Falling - Amusement parks are full of fun. In this challenge youth use their imagination to build a single ride or a whole park full of rides. Adding scenery and backdrops with paper or craft items is encouraged. At least one of the rides in the amusement park must use a sensor to trigger an action. The models may be built using any type of materials including LEGO WeDo, LEGO technic, hobby motors, erector sets, K'Nex, craft supplies, etc. They may be programmed with the LEGO WeDo software, Scratch or any other control system. The entry must include at least one sensor and one motor.  Builders are encouraged to add sound effects to their display. Youth may enter as an individual or a team.

Youth entering the Google Doodle Scratch Contest do not have to be present at the contest.

Educational Display and/or Demonstration
