In this Episode, we stop at the pinless attachments for the Box Robot 2 and especially for the constructing a frame. This frame is then used for further extending the robot with attachments.
The most stressed wheel in our system is the driven wheel. We've already fixed the problem with the driving wheel of the scissor mechanism and now it is time to look at the drive LEGO Mindstorms wheel.
Where is the math while turning? Is there any math involved? Should there be?
Here is the task for adding a beam on both sides of every gear wheel in your attachment.
The next important step when turning with a robot is to learn how to do an Arc turn.
One of the very common problems with the LEGO Mindstorms and LEGO Technic Gear wheels is then a tooth is skipped. In this video, I would like us to discuss this challenge and how do we solve it.
Spinning with the VEX EDR robot involves the use of both motors. The left and the right. Every robot with wheels could spin and this makes not exceptions.
It this episode we would present you with our attachment for lifting the robot.
How does this construction of VEX EDR turn? It has two motors. Let's start with turning right
Experiment with changing the orientation and direction of gear wheels. Here are part of the tasks that you should complete before moving forward with the course.
With this video tutorial, we start with Turns with the VEX EDR robot.
In this tutorial, we would drive the scissors mechanism and there are a number of rules that we must follow
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.
