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.
Detecting direction using the camera in Scratch is a very useful tool for controlling our sprite using movement. Now you will learn how it functions and how to use it!
How can you accumulate some energy in an LEGO Mindstorms EV3 construction an use this energy at a later moment? How does a Flywheel work, why is it important and what is the purpose? What is energy, inertial moment and angular velocity. These are just some of the questions we would answer in this series on Physics and LEGO Mindstorms.
In this video tutorial we demonstrate the use of the motion sensor and how it could be use to turn precisely to 90 degrees. We demonstrate some of the caveats of the sensor and how sometimes it does not work as expected. Like you set the robot to turn until the sensors detects 90 degrees and at the end the robot is not at exactly 90 degrees.
We have the following behavior expectations from you during this course:
You ask the question.
You will probably err before you succeed.
You should work as a team. Share solutions with others, help them and allow them to help you.
When the teacher speaks, this is important to everyone.
You should read your lesson before you come to class.
(LEGO humans of course, not real humans :) ). Working on World Robotics Olympiad 2014 elementary challenge. Collecting modules, bringing them together and lifting them. A very funny and interesting competition that we would explore in this and the next video tutorials from the series
Raw footage of how to accomplish the mission. A more polished version might be uploaded soon.
This video is part of a series where we show you how our Box Robot accomplished the M10 Steel Construction mission 10 out of 10 times. The attachment is a basic lever and all the 'heavy lifting' is done by the x-y movement of the Dominator robot. This mission is one of the hard missions, because the construction is big and heavy and this requires precise movement of the robot.
How to change the direction of a beam from horizontal to vertical.
Third, and last video of this series on how to use ONE attachment to solve the FLL 2014 World Class missions.
Starting with the World Robotics Olympiad 2014 Junior-High challenge we first catch the object on our path. We discuss a good mechanism for catching and lifting balls that can do two movements with one motor.
This video tutorial is about understanding the "magic". In this video tutorial, we would conduct an experiment and will look at how exactly does the integral part of the PID algorithm compensate for the error that the LEGO Mindstorms EV3 robot makes.
In this second video lesson on catapults we improve the stability of the base of the robot. An important feature of the new base is that it is not bending. Use the same principle in all of your constructions to achieve better, stronger robots.
Robotics competition is a large part of the FLL Competition. The field contains missions which give points and the main purpose is to gather maximum number of points for 2:30min. FIRST LEGO League competitions have different themes every year but the tasks have similar functionality. In this video tutorial we will give a brief of missions in Senior Solutions (the theme for 2012).
How can you be sure your image on the display is seen when the program ends?
Raw footage of how to accomplish the mission. A more polished version might be uploaded soon.
Based on your feedback we have decided to show you the live process of building a complex LEGO Mindstorms Competition robot without having the whole robot ready yet. We are continuing from part 1 where we finished part of the 'front' of the robot and we arrived at a construction that we didn`t like and would fix in this video lesson.
This tutorial demonstrates how a robot could align to a black line. The code for the program is available in the course. Aligning to black lines is popular at robotics competitions like FIRST LEGO League as it is the primary way to know where you are on the field and to develop a program that is reproducible. The attachment uses Luly, a small LEGO Education SPIKE Prime competition robot with 3D building instructions as a robot base.
This video tutorial is part of the series on how to make your robot 100% precise and accurate. We accomplish the M06. SPACE STATION MODULES mission 9 out of 10 times. The attachment works. Every time the attachment is started in successfully accomplishes the mission. It moves forward and attaches the space station module with the space station.
In the video we improve on the robotics mechanism for pushing the different blocks out of the robot container. We continue from the previous video.
This video is part of a series where we show you how our Box Robot accomplished the M07 Swing mission 10 times. This mission has a black and white line parallel right next to it, the only thing you need to figure out is how to avoid the first supporting beam of the swing. The Dominator robot waits to be clear of the beam and then uses the x-y movement of its front mottors to position the lever so it pushes the swing loose. After that the robot moves back and is ready for action again.
In this video we look at the robotics mechanism for dropping the different blocks into the different region on the World Robotics Olympiad 2013 field.
How to make the robot stay idle while the program is still running.
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.
We will build the EasyBot quick robot and will explain how to follow building instructions.
In this tutorial, we would drive the scissors mechanism and there are a number of rules that we must follow
All worked as expected, up until know because the robot got lost. This happens when we turn right and the line does not continue to the right. Now the robot must somehow understand that it is "lost" and escape.
