Mission Challenge LEGO
The goal of this category is to build a robot at the competition and conduct a designated mission on the day of match.
This category is meant for young robotics enthusiasts that want to compete with other participants at a beginner to medium level. The age limit for this category is 16 years.
General specifications
The robot and the solution for the mission must be solved only using a robot built out of Lego Mindstorms devices (RCX, NXT, EV3 or Spike Prime).
Under the rules of the game, teams will have to build at the competition an autonomous robot, that will have to accomplish the mission according to the mission specifications received at the start of the competition while also respecting the specifications in the regulations.
1. Notification
We realize that there are other variations to the rules for Mission Challenge, while there are many similarities between other variants the official Robotics Championship rules posted on the website will be used, for this competition we ask that participants to read and be familiar with this particular rule set at the time of the competition, in order to avoid surprises.
This category is inspired by the games organized by the International Robot Olympiad Committee (IROC). (see more at https://www.iroc.org/2018-rules-1 )
2. Team
2.1. A “team” is composed of one to five participants who will build a robot at the event. Each team should also have one adult present with the team. One adult can represent multiple teams if they wish.
2.2. The robot must be an autonomous robot constructed by themselves at the competition site to regulation and mission specifications. This robot category does not permit prebuilt robots, kits will be inspected before the start of the category. There will be a predefined time for adjustments and changes to the robots and their programming during the event.
2.3. Each team / robot will receive a check-in number and should have a unique name or identity to be easily recognizable by spectators and officials when they are on the field and when they score. The identification label will be placed on the robot during the technical inspection after the building of the robot is done.
2.4. Each team that has built a robot for this category will have equal chances and number of tries. During the trials, only two members can approach the track, the other team members must follow the trial from the public or remain in the participants area.

A. Mission objective
The robots compete one after each other. Each robot must reach the top of the staircase as fast as possible climbing one stair at a time, using his legs. Touching the staircase with other parts is not permitted.
B. Course time
Time is measured from the start signal until the robot reaches the top of the staircase. The robot is deemed to have finished the mission when both its feet are in contact with the end of the staircase. The maximum time admitted to complete this mission is 5 minutes, at this time the robot position shall be noticed for scoring.
C. Timekeeping
Time must be measured with an electronic gate system or by a judge with a stopwatch , based on the availability of equipment. In either case the recorded time shall be final.
D. Autonomous control
Once the start signal has been given the robot must remain fully autonomous or it will be disqualified. The robot must be disconnected from any network during the mission to prevent outside intervention.
E. Interruptions
- If a robot falls off the staircase it gets a second chance to complete the attempt. The robot will be placed at the first step.
- If a robot falls off the staircase or gets stuck because of various reasons (low battery, hot motor, script error, etc.) it gets a second chance to complete the attempt. A time interval up to 10 minute shall be granted to solve the problem before the retry. The robot will be placed at the first step when the restart will occur. In case of restart, the best attempt shall be considered for scoring.
- If a team refuses the second chance or the robot cannot be fixed in the given interval, the first attempt shall be considered for scoring.
8.2. Obstacle navigation mission
The robots will compete one after the other. The aim of the game is that a robot who walks on two legs must complete a course with obstacles in the shortest time.
A. The time in which the robots are allowed to finish the course is 5 minutes.
B. Each robot has in total 3 attempts. The attempts are distributed in 3 different time slots, each slot has a 5 minutes time limit. In each slot a robot has the right to make only one attempt to finish the course.
C. If one robot will not come to make his attempt in one slot, he loses the right to do it. Two attempts in one slot are not allowed.
D. Depending on the number of competitors the time can be extended or reduced.
E. One attempt has a time limit of 5 minutes to be completed. If the robot gets stuck, one restart is allowed. The robot will have to restart from the start position.
F. If the robot doesn’t finish the course in 5 minutes it will be stopped and the distance covered will be recorded.
G. The final classification will be made taking in consideration the best time for each robot.
H. No objections shall be declared against the judges' decisions. If there are any objections the team can be disqualified from that match.
I. Each team has the responsibility to follow the starting grid (schedule), displayed on the website and in the teams area.
9. Playing the trial

10.3. Time record is based on the measuring instruments or referee’s timer. (If you are declared as TKO or Robot stop by the referee, the time record will not be accepted as the final score.)
10.4. The final score considered will be the best score out of the 1st, 2nd and 3rd attempt.
10.5. The standard of the scoring system is based on quantitative standards: timekeeping and distance record.
10.6. Order of priority according to attempts If the result is the same, the winner will be decided after comparing the result of other attempts.
10.7. For the stair-climbing mission the robot who will reach the end of the staircase in the allowed time, will receive 10 points. The rest of the robots will be ranked depending on which step they arrive on the staircase. If more robots stop on the same step they will be ordered using the time when the robot is considered stopped by the referee. The minimum amount of points obtained in this challenge shall be no lower than 1 point.
10.8 For the obstacle navigation mission the robot that will finish the course and will have the best time, will receive 10 points. The rest of the robots will be ranked using the time and the position on the course. If more robots stop in the same place they will be ordered using the time when the robot is considered stopped by the referee.
The minimum amount of points obtained in this challenge shall be no lower than 1 point.
10.9. The final ranking is made by summing the points from all challenges for each robot. The robot with the biggest number of points wins the competition.
