The LEGO EV3 Mindstorms brick can be programmed from the brick itself. The motors can be moved forward/backward and even simple programs could be implemented without even touching the EV3-G software at the computer
Tasks for introduction on building robots.
Based on your feedback we've build a course for introducing new students to the LEGO Mindstorms EV3 programming and construction. It is designed for school groups, competition teams and students alone in home that can get our feedback on their progress
With this series of videos we are looking at FIRST LEGO League 2013 Nature's Fury competition and we are building a robot for accomplishing some of the mission. It would be a tutorial with at least four parts and we are building a complex attachment that could catch, lift and release different parts with only one motor and rubber bands. Not one, not two, but three movements with only one motor.
The attachment is now so advanced that we can do two tasks at once with it in order to solve the FIRST LEGO League 2014 World Class Search Engine Mission.
The third part of the series the goal is to extend the robot attachment so that we could solve the second part of the FIRST LEGO League World Class mission challenge - to take the loop.
In this tutorial of the series we would get into more details on how the flywheel works, what's its purpose and how the whole attachment is triggered with the first rubber band.
Let's try to integrate more of the things we have learned into a single attachment. One that could accumulate energy, conserve it and use it at the appropriate time. All this because of a Rubber Band and a Flywheel - and if you don't know what a flywheel is you should definitely watch this videos
The Department of "throwing" is ruled by rubber bands. Impulsive power release in a short amount of time. In this video we are building an attachment that throws a ball and accomplishes the FIRST LEGO League 2012 bowling competition.
With this attachment we just share an idea. The attachment was build by an FLL team called Brother in Arms and they needed a way to turn two axles in different direction, one at a time. The attachment was not used in the final robot design and construction, but presents a nice idea.
Enchansing a previous attachment, but only this time we are solving the FIRST LEGO League 2012 Medicine mission. There is a lever and a rubber band. When the lever is released the rubber band activates the attachment.
In Episode 58 we introduced you to an LEGO Mindstorms EV3 Modular robot. Mic Lowne wrote to us and had that robot remade, because it used too many blue lego pins and could not be build using one EV3 kit.
As an extension to the previous video we talk about the Hi Technic Color Sensor again.
Урок обясняващ, какво е масив и начални операции с масиви.
Based on a request from Abdulah we decided to build a tutorial on how to use Hi Technic Color Sensor and EV3-G Software. There is a special block imported in the software that helps you use the sensor.
The attachment builds on previous episodes this time using two LEGO rubber bands. When a lever is released the rubber band exerts pressure on it and moves it in a circular motion. As an example we are solving the 2012 FIRST LEGO League, Senior Solutions, stove mission (which was quite interesting as a mission)
Pinless attachments are smart and quick and could make a big differences between two robot constructions. In this video we are sharing a nice idea for a pinless attachment placed below the robot.
Rubber bands in the LEGO Mindstorms sets are very handy when it comes to collecting objects, especially loops. The mechanism most of the time could work like this - an axle is pushed, a rubber band is released and a lever collects the loop.
The previous rubber bands video showed a way to trigger the rubber band without a motor. This video gives one more idea on how to lift an axle and in this way release the rubber band. Use the idea for you LEGO Mindstorms robot constructions.
In part one we build an attachment that uses a rubber band to solve a competition challenge. The rubber band was released with the use of a motor. In this video we are removing the dependency on the motor and you could use the motor for other missions.
The robot attachment build in this tutorial gives an idea on how to release a rubber band at a specific moment using a motor. It's a simple, but yet powerful technique on using rubber bands.
Rubber bands can be quite powerful. Based on several requests from you we are starting a series on using the LEGO Rubber bands available in the Mindstorms set.
This time we stop on "Using the Right Senses" mission, or actually on how to solve the "Right Senses" mission without "Senses" (sensors). To achieve that we use the carabineer counstructed in one of the previous tutorials, of course after a small modification.
Here we continue examining FLL 2014 World Class missions. We show different ways, for putting the insert in place as well as taking the loop from the robotics arm. Some of them are quite specific, which reminds us, that you need to think out of the box, while solving the missions.
"What is the light in the room?" - should it even matter. You can use one program for all lighting conditions by calibrating the color/light sensor of the LEGO Mindstorms EV3/NXT robots.
Based on a request we are showing the robot construction with two rear motors instead of a differential. In this way, as a construction, it is closer to more students, but much more challеnging for programing.
It has been a long road with the last 8 BigDaddy competition robots video tutorials, but we finally arrived at the Differential Lock.
