How to use the robot when the buttons are not accessible.
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 EV3 Gyro sensor is quite powerful, but there are some little tricks when using it. In the previous episode we showed a hardware solution to the problem and now we are exploring how could the sensor be calibrated from the EV3-G software. Thanks to Sharon and Faye (full names omitted) for the request for this video.
There are a number of tools available online to help you play the game. You just seed the initial conditions and leave the game. Let's look at some of the sites.
Let's explain the problem of just waiting for the Gyro sensor to detect an angle and think of why the robotics systems work like that.
We will learn how to connect and disconnect LEGO cables and on which ports exactly to connect the motors.
Why we change the robots all the time and what to observe in each new robot.
There were a few problems with the 40 teeth gears that we were using. Let's list some of them
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.
A robot that contains balls and releases them. It counts how many balls to release depending on the "treasures" it has hunted on the field. This is part of the World Robotics Olympiad 2015 Elementary challenge.
How to place the cup on the robot so that the challenge is challenging.
Active robot attachment for the LEGO Mindstorms EV3 Box robot chassis. The attachment is placed on the top of the robot and uses a system of two gear wheels to transfer the motion to a lever and to .... lift things.
Building instructions for a simple car using an EV3 Large motor for turning the front wheels and EV3 medium motor with differential for driving the rear wheels.
This block accurately turns the robot to a specific angle. One of the most useful blocks that you could use during competitions. The block makes the robot turn and when the robot makes an error, the block will correct for this error.
Finally, you can be sure that the robot has turned to the specific angle that you want.
You have three inputs
VERY IMPORTANT: This is a block for EV3-G. You download and import this block from Project Settings->Blocks->Import. If you are using Internet Explorer or Microsoft Edge and you click to download the file it will try to save it as "zip". DO NOT SAVE IT AS ZIP. Save it as "ev3s" or just PLEASE, STOP using Internet Explorer or Microsoft Edge. This will dramatically improve your browsing experience.
The experiment contains a plot of the Curren Power of Motors B and C and the values of the Gyro Sensor when the robot is moving with a power of 100%. What you could see is that it is not actually moving with a power of 100% because the current power is about 75-80%.
This attachment accomplishes the Into Orbit Space Walk Emergency mission from the FIRST LEGO League Into Orbit 2017-2018 competitions. The base robot is the SUV Competition Box Robot from LEGO Mindstorms EV3.
The program for this attachment is at Programs/w415dz-fll-2018-attachment-to-accomplish-the-into-orbit-space-walk-emergency-07-robot-game-missions-program.
Soon we would publish and a video of how the attachment works.
This video tutorial contains a detailed explanation on how we accomplish the FIRST LEGO League 2018-2019 Into Orbit mission called M14. METEOROID DEFLECTION. The mission is a simple throw of a ball. But of course the ball should reach a specific mission model and arrive at a specific place. And that's always challenging.
This project is for Barco - LEGO Mindstorms EV3 sailboat robot. The project includes two programs.
The first program makes the robot go in a square shape, using the gyro sensor for better accuracy. The second program makes it go in a triangle, again, using the gyro sensor. These programs are a great way to learn how to use the gyro sensor.
This is the attachment to accomplish Fll 2019 M10 mission with the Dominator robot. You can see how to attach the attachment to the robot in this tutorial.
