Before moving forward here is the simple task of building the mechanism and extending the legs. Extend the legs to fifteen LEGO units.
The final way for lifting our box robot is by using a scissors mechanism. In this Episode, we would discuss the benefits and advantages of this mechanism.
Бележки за построяването на Петминутен робот.
В това видео ще покажем как се строи Петминутният робот и ще го прегледаме накратко.
In the EV3-G software, you could use negative numbers for power and rotations. In this episode, we would look at what is the meaning of this numbers and make a few notes of where the teacher must be more careful.
Once you start turning how to do you a whole 180 degrees turn. The robot almost does it, but not completely
В EV3 софтуера за програмиране има Танк блокче за движение. То ни позволява да задаваме различни мощности на всеки мотор.
В живота подобно нещо се използва при автомобилите. Системите за управление на сцеплението с пътя (tracktion control) предават различна мощност към всяко колело на автомобила, така че колата да остане стабилна на пътя и да не поднася.
We will share the idea behind that challenge and how to conduct the challenge in a classroom.
Let's make a competition - there is a pole that the robot must turn around and return home.
След като вече изпробвахте и се справихте с предизвикателство, включващо поредица от инструкции, искаме да ви представим някои добри практики.
Специално предизвикателство за програмиране на робота, така че да се движи като йо-йо.
How to align the wheels and how much should you push for this solution?
There were a few problems with the 40 teeth gears that we were using. Let's list some of them
Build a similar mechanism to this one. Similar, but for your robot. This is the task for you. Try, give yourself half and hour or even an hour.
Time to lift the robot. The first approach is by using the 40 teeth gear wheels that come with the LEGO Mindstorms EV3 and NXT robotics sets.
Remember the passive/active attachment separation that we are making at FLLCasts.com. This applies for all the attachments and in this Episode, we are looking at how to use a passive attachment.
What is the end result? - have the attached on the mission model. What is the mechanism the would make the robot hang on the mission model.
Note for the teacher on how to organize the class to use different robot base constructions to accomplish the mission for lifting.
Build a robot base to use in the course. You can use the robot base provided by us or you can build one yourself.
Don't limit yourself to the box and think of different ways to lift the robot.
How to organize the different robots and group of students when working on lifting the robot.
Where should you lift the robot? Especially if you don`t have the mission model that we are using
How should an instructor use this course when working with students and a group of students in school
We've already build a number of resources for lifting at FLLCasts.com. But at the end of this course we would have a robot that lifts itself and hangs on the mission model.
The FIRST LEGO League competition is similar each year. With a little experience you could accomplish most of mission. The goal of this episode is to introduce you to the course, its purpose and approach.
Ще разгледаме типичните причини защо роботът ви изобщо не иска да се движи.
When you first start the EV3 brick, you see the recent programs menu. Let's see what it is all about.
