FIRST Lego League

5 stars based on 72 reviews

The students work out solutions to the various problems they are given and then meet for regional tournaments to share their knowledge, compare ideas, and display their robots. The teams also receive a list of tasks, called 'missions', to complete involving each model on the mat i. The robot has two and a half minutes to complete the missions. Each team has a minimum build period of 8 weeks to analyze the challenge mat, design and build a LEGO Mindstorms robot, and program it to fulfill the given missions in any manner they see fit.

The robot must be autonomous[4] and may contain only one LEGO Mindstorms programmable block and no more than 4 motors. In addition to the live robot run, the competition has three additional judged sections with the purpose of providing teams with feedback on their achievement of the FIRST LEGO League learning objectives.

In most regions, teams are also asked to perform a teamwork activity usually timed. Thirdly, in the Project[2] the students must give a 5-minute presentation on research a topic related to the current challenge. The required steps of the project as teams to first identify a problem that is related to the topic of that year's competition, then create an innovative solution to their identified problem by modifying something that already exists or creating something completely new an "innovative solution"and then they must share that solution with others, such as real world professionals who have expertise in the annual challenge theme.

When the official competition convenes, each team brings their robot to compete on an official challenge mat identical to their own. Two members of the team are allowed at the board during a match; however, they can switch out if needed. In the case of a serious problem, such as the entire robot breaking down, the entire team is allowed at the board for as long as the problem persists. Members are not permitted to bring additional robots or board items from other practice tables to the board during competition.

The robot starts in an area marked as 'base', a white area in the corner or to one side of the table. In base, two team members are allowed to touch the robot and start program. If the team touches the robot while it is outside of base an 'interruption'the referee will issue a penalty, resulting in a 5-point deduction.

These are stationary LEGO models that negate the final score if they remain until the end, providing an incentive to not interrupt the robot. The robot is not required to return to base; some teams have completed all their missions without returning to base during the time allowed to complete the missions.

In fact, in the —09, [6][7]and challenges, points were awarded if the robot was in one of two specified areas, not including base, at the end of the two and a half minute match. The robots are programmed using one of the block-based programming environments: All these are built around Labview. Teams in different parts of the world have different times allotted to complete the construction of the robot, due to the varying date of qualifying tournaments but must have a minimum of 8 weeks from "Global Challenge Release" the date, usually in late August, by which the details of the missions and research project become available to the public.

In the —07 season, nearly 90, students on 8, teams [9] from around the world competed. The initial levels of competition are managed by an Affiliate Partner Organization commonly affiliated Universitieswho are led by an Affiliate or Operational Partner Representative "The Partner".

The Partner has complete control over all official tournaments in their region. Some States represent an entire region while others, like Central Floridarepresent a mix of Counties within the State. Certain territories have 3-tiers and may also employ a State Championship. Throughthese events will be held first in Houston, Texas at the George R.

As such, teams are normally allowed to win only one core judged award. Teams can win an additional award based on their robot's performance during the robot game competition portion of the tournament. In andteams using the RCX could earn "fairness bonus" points based on the fact that the RCX was less technologically advanced. Officially registered teams can also be nominated by their region for the Global Innovation Award, where they could win a grant to make their innovative solution to the annual challenge theme's problem a reality.

All submissions are reviewed by a panel of judges consisting of experts from engineering and industrial fields as well as experts in the challenge theme for that year. Teams are judged on problem identification, innovation, implementation, and effective use of STEM principles.

Teams compete to advance levels. First, teams go to qualifying tournament. A handful of winners are then selected based on their performance at the qualifying round are then invited to the state championships. Awards are given at both rounds. Winners from the state competition usually teams are then invited to the World Festival. From Wikipedia, the free encyclopedia. This article needs to be updated.

Current season, competition or edition: It focused around a group of astronauts stranded in a space station; missions included pulling a lever to allow the astronauts into a chamber and delivering oxygen foam balls to different sections of the playing field.

In this challenge, robots had to complete challenges prior to the eruption of a volcano, [22] such as rescuing a stranded scientist, barricading a village from lava rocks, deploying a gas sensor, and retrieving crates of samples, among other volcano-related tasks.

Robots had to complete tasks on an Arctic themed board such as retrieving medicine barrels, and rescuing minifigure scientists from polar bears. Robots completed tasks such as clearing rocks off a soccer field, harvesting and delivering food loops, collecting toxic barrels, activating a windmill, and other city-related tasks.

Centered around various robotic assistant systems for disabled persons, robots demonstrate how the systems are hopefully able to solve the given problems in a satisfying way. Involved marine-themed tasks such as mapping a sunken ship, deploying a research submarine, and cleaning up a shipping spill. The challenge is developing anything using nanotechnology [26] that improves or makes life easier from medicine to computers to the environment. The challenge is on alternative energy and features tasks such as moving power lines, fuel sources and planting trees.

The challenge focuses on the Earth's past, present, and future climate. Students must research a climate problem occurring in their area, find a solution, then share it.

They also have to research another area which has the same problem as their area. Featured moving balls, bicycles, computers, setting up levees, etc. The challenge centers around efficient transportation [30] and teams are to solve a particular problem with the mode of transportation that they have chosen.

The robot game includes activating access markers, collecting loops, toggling a lever to move a truck, avoid warning beacons, parking at one of two specified locations, etc.

Explore the cutting-edge world of biomedical engineering to discover innovative ways to repair injuries, overcome genetic predispositions, and maximize the body's potential, with the intended purpose of leading happier and healthier lives.

By Steve Westfall and Dennis Malovich: Honours Computer Science Students. It is designed to get children excited about science and technology. Teams, comprised of up to ten children with at least one adult coach, compete in the challenge. In the FLL, the challenge is comprised of programming an autonomous robot using the LEGO NXT robot set to score points on a themed playing surface and create an innovative solution to a problem as part of a research project.

These two elements - the Robot Game and Project - make up what they call their yearly Challenge. RoboCup is an international research and education initiative which is more advanced than the FLL. It is an attempt to spawn AI and intelligent robotics research by providing a standard problem where a wide range of technologies can be integrated and examined, as well as being used for project-oriented education. RoboCup currently uses a soccer game as its primary domain.

In order for a robot team to actually play a soccer game, various technologies must be incorporated including: RoboCup is a task for a team of multiple fast-moving robots within a dynamic environment. In the past, all FLL competitions have involved the building and programming of one autonomous robot to achieve a mission. To date, there have been no challenges that involve multi-agent teamwork co-ordination between robots to achieve a goal or complete a mission.

Due to the Bluetooth capabilities of the Lego NXT, we began to think that this type of challenge could be an excellent addition to the FLL as a new challenge. However, due to competition time constraints and available hardware, it first appeared that a challenge of this type may be better suited for either an older age group of contestants or as a new RoboCup segment. We found a wealth of information scattered across the internet that was extremely helpful in learning just what kind of capabilities we were dealing with.

Once armed with this new understanding, we took a closer look at both the FFL and RoboCup competitions. Although at first, we thought that the RoboCup competition may be a better fit for our project, once we learned more about the NXT, we realized that the RoboCup competition was a little too advanced for anything that we could put together with the resources we had over an eight month period.

Therefore, we took a closer look at the First Lego League. Our initial reservations about trying to create the first challenge for the FLL that involved multi-agent teamwork co-ordination between robots to achieve a goal or complete a mission were centered on the age of FLL contestants, competition time restraints and available hardware.

Normally, teams comprised of up to ten children ages 9 to 14 with at least one adult coach, compete in the challenge and program one NXT.

We had very lofty goals right from the outset of this project. Since we North Americans are more enamoured with the NFL style of American football as opposed to soccer, we decided that our challenge would be to create NFL style teams of NXT powered robots that would compete against each other.

Since developing Java based programs that use Bluetooth protocols is a little more than the average 9 to 14 year old is probably ready to handle, we needed to develop a core set of programs that could be easily adapted for the competition or our contestants would never meet the time constraints. In order to simplify things for the FLL, we created two remote PC interfaces that control each of the teams through the use of Bluetooth.

As a starting point, we added three plays for the Offensive team that can be run with the click of a button. Each NXT on the Offensive team has pre-programmed instructions to carry out depending on which play is being executed. However, each remote interface can be expanded to include up to nine plays each.

Our new challenge would ask the FFL contestants to program the actions of each robot for each play. This way, teams could work together to decide which NXT needs to perform which actions for each play and work towards a common goal of either scoring a touchdown or stopping the other team from scoring.

Through the use of our interfaces, contestants would not need to program any complicated Bluetooth protocols and they would still get to enjoy the fun of controlling a robot by remote control. Create workspace in eclipse and import source code. Be sure to include all libraries. Build all 8 robots and download individual code to each robot. Insert bluetooth dongle and begin set-up for each robot.

Begin with a flat surface. The field surface is best created using standard sized bristol board. The length is 4 by 2. The border is 30cm and the bristol board color is blue. Connect the robots using bluetooth: Connect each individual robot by pressing the connect button. Once robots are connected, robots can be maneuvered using the control buttons on the interface. Do this for the Defensive robots as well. Use the controls on the interface to set the robots in their start-up positions.

These positions can be seen in our video demonstrations. The Offense and Defense occupy one half of the field each.

All plays begin from the main start-up position. The ball must be placed underneath the Center before play can begin. The play buttons on the interfaces Offense, Defense should be pressed at the same time.

A point is awarded when the Running Back with the ball in the claw successfully crosses the end line of the opposing team without going out of bounds. Regardless of whether a point was awarded, all plays begin from the main start-up position.

Teams can choose how many plays each team can run. The team with the most points wins. CSS template by gorotron.
