Let's record the values of the Gyro Sensor while the robot is moving and is trying to keep its orientation straight. This is an interesting experiment and we will have to use file access to write the values to a file.
We can Turn Right. We can Turn Left. How do we decide which way to go if there are lines both to the left and to the right. Check out the video.
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 video tutorial we would look at the mission run for M09. STRENGTH EXERCISE. The mission is to lift a heavy object in the air. And that could a complex mission. It requires to use gear wheel and the attachment should be quite strong. The tutorial contains only the mission run on the field. We accomplish a single mission.
Showing the same run, but from a different angle. This allows you to see more of the way we sensors work and how exactly the robot positions itself.
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.
(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
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.
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.
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.
How can you be sure your image on the display is seen when the program ends?
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 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.
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.
After several questions about the use of the LEGO Mindstorms NXT Light Sensor with the EV3 software, we have decided to go through this problem in this video tutorial and pay special attention to the Raw Sensor Value Block.
We continue from part 4 where we made a controlled experiment to transfer power from a Mindstorms motor to the rear wheels. The construction was too complex and inefficient and in this video lesson we are improving it by lowering the differential and removing all gear wheels from this LEGO Mindstorms EV3 Competition robot.
Extend the previously build attachment for the FIRST LEGO League (FLL) Nature's Fury competition so that we can move the Truck and Ambulance up and down.
We continue from part 3 where we finished part of the 'rear'. Power is transfered from a motor to the wheels but having about 16 gear wheels makes it more than complex for this LEGO Mindstorms EV3 Competition robot.
It has been a long road with the last 8 BigDaddy competition robots video tutorials, but we finally arrived at the Differential Lock.
Arriving at a final solution. There is still room for improvement on using the Mindstorms Ultrasonic Sensor for aligning to walls, but we hope the whole five videos could give you a good idea of how to start with a problem and reach a solution.
The telephone game played with LEGO Mindstorms EV3 robots relies on the Color Sensors and the detection of colors. Sometimes the robots won't work. They could be influenced by a number of factors like the position of the sensor and the lighting in the room. This tutorial is a demonstration on how to account for and resolve this issue.
