You can download for Windows or Mac the EV3 Education software.
When installing, select the Student version. You can create programs and save them into a USB memory stick. Remember to save it with version number like: name_v01, to identify the version of the program. Any changes to it, save it as a new version to keep track of modification. Be sure to add comments (blue boxes) or general comment to the program (sticky notes) Link to download EV3 software: education.lego.com/en-us/downloads/mindstorms-ev3/software

You can download this PDF file with some block samples for EV3.
Samples include moving by distance passing the distance in cm or inches, passing the wheel diameter. It also includes move until detecting light intensity or color. drive.google.com/file/d/1oKoNtCbTsMqbROlXijvzdaDcCbsk99Ju/view?usp=sharing One excellent site to help learning about Ev3 programming and FLL design and programs is the FLL Tutorial by the Seshan brothers, who are Mindstorm community partnes, founders of EV3 Lessons and the 2018 World Festival Champion's award winners. You can access their site at the following link:
flltutorials.com/RobotGame.html Review the information and discuss with the team the best approach for a design and programming. Ready to launch! Gears are nice elements for EV3 robots. You can combine them for generate specific movements or provide additional power for movement. Look at the image below, image 1 is the configuration with one large motor, one gear connected to the motor and additional four to generate a simultaneous rotation for two wheels connected at the large gear (one attached to the motor and the last one) If we rotate the motor clockwise, see the behavior of each additional gear in image 2. The wheels will move clockwise, giving power to the EV3 movement. If we rotate on the other direction then we will have a similar effect in the new direction of the rotation, in the case of image 3 counter clockwise One mission for Into Orbit challenge is to move the robot on an asteroid terrain, how can you use gears to provide strong movement and accomplish the mission?
Into Orbit season is here! Please be sure to read the participation rules: firstlegoleague.org/sites/default/files/hydro-dynamics/new-participation-rules.pdf Thanks to FLLTUTORIALS site, you can have a tool to use to draw a plan for the missions:
You can access to it at the following site: flltutorials.com/Resources/2018/drawplan/index.html In less than 2 days, the new Into Orbit mission will be available for all teams in the FLL family.
To start preparing for the new challenge, let's define some guidelines: 1.- Understand the mission: Read, work with the team building the mission challenge, play with it to find out the best way to solve challenges. 2.- Plan the robot movements for the game: Sometimes we would like to go for the easy ones, leaving some others behind, try to look for challenges close to base, which one can use the same design or attachments, how many points we plan to get? Use your notepad for notes, and define a planning strategy for the mission. 3.- Virtualize your strategy for the game plan: You can either take a picture of the challenge set or use information from FLL to draw possible paths for the games. The paths should leave base and return to base as well. Any possible obstacles? Generate if possible a pseudo-code plan. 4.- Build and program: This is the part were the team will build the robot, with all possible attachments for the missions to run. The programming part can be done by using the previous pseudo-code information, or writing a pseudo-code prior to start coding on the EV3 interface. 5.- Test, Debug and update: With the program in place, the design to use is time to test, take notes of problems, check the code, and make the corrections on your notepad first before updating the code. Please be sure to number the program name so you know the version running and do not overwrite the previous one. For additional information about Pseudo-code, you can visit EV3lessons site at: ev3lessons.com/en/ProgrammingLessons/beginner/Pseudocode.pdf The guidelines are based on several information provided by FLL coaches, EV3lessons web site and feedback from team members. For the new challenge coming up this Fall, FLL provided new participation rules, please read the new rules from the link provided: FLL new participation Rules
:Programming the EV3 for a competition requires several blocks. Sometimes we repeat a sequence of blocks having a long set of blocks causing some errors and hard to debug or find where the program is failing. To help minimizing the program, EV3 software provides a tool called my block builder. First you need to define a block of programs that will be created as one my block: Select all block you want to be part of My Block definition Go to Tools- My Block Builder You can define an icon for your block, type a name for it and a brief description. If you do need to define parameters, then click finish All the previous blocks will be saved into one my block, this will be saved in your EV3 library to be used on other programs.
If you create a new program and go to the last tab at the bottom, you will see all my blocks you created. |
