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.
In this episode we build a reusable attachment for a LEGO Mindstorms EV3 robot that changes gears orientation and direction. It is one of the most useful attachments that you could use to move levers up/down and right/left. Adding the attachment on the robot takes 2-3 seconds and shows a very useful general principle of how to build reusable attachments.
You think that you can quickly change the attachments of your LEGO Mindstorms EV3 competition robot? Are you sure? In this first episode of the series you will see how to create and attach attachments without using pins and how faster and easier this could be. You will see the design logic of a few attachments and how they work on the field.
If you think that the quick pinless attachments shown in video 63 are quick enough, see this tutorial and you will find out that the quick pinless attachments could be even quicker. These attachments can work without motors but by using the inertia forces.
We should multiply the error by a certain number and then add it to the steering of the LEGO Mindstorms Steering block. In this way, by changing the coefficient we change how much/fast should the proportional part influence the steering of the robot.
These are building instructions for one of the greatest LEGO Mindstorms attachments that we've built. Super simple and easy to follow and at the end, you have an attachment with a rubber band that controls a lever and that could lift objects from the field. It could lift them up. Also because it is with a rubber band you don't need a motor and you could use the motor for other attachments.
This is a mission model designed for Off-season competition challenge. It's built with LEGO Education SPIKE Prime following the design of the successful LEGO Mindstorms EV3 versions available at Construction plates mission models. FLLCasts Off-season Challenge with LEGO Mindstorms EV3. Check the courses in which this attachment is used for more information and tutorials on how to use it.
Building instructions for the robot build with LEGO Mindstorms EV3. It is called "Frankenstein" because the two motors are in two different directions.
This LEGO Mindstorms robot base is small, compact and packed in a very small volume. The goal of this constructions is to be used as a base and to show yet another way to experiment with adding motors to the brick.
It sparks. It's sparkling. Well, the goal of this LEGO Mindstorms building instruction is to spark the imagination when the base of the construction is very simple. Just two motors with the brick above them and one of the most classic ways to attach them together - with angled beams.
The construction could use EV3 or NXT wheels, so chose wisely. As a robot chassis base, it is suitable for all kinds of extensions. An interesting thing is the motors are attached to each other with a frame which is getting very popular in the EV3 world.
Building instructions for a LEGO Mindstorms EV3 robot where the motors are at the back of the horizontally placed brick and they are placed vertically. This construction is difficult to turn with but at the same time is quite high and could be used as a base for different trucks or animals.
Building instructions for a LEGO Mindstorms EV3 robot where the motors are placed in an unusual manner. They are vertically placed on the sides. This robot construction base is very convenient for a quick and interesting robot on which you could build.
Building instructions for a LEGO Mindstorms EV3 robot that could be completed in about 3 minutes. Could you do it? Try it.
We use this robot when we need something very fast for a demonstration or a small competition. Just attach the motors and you are ready. It is fast.
Building instructions for Module 1 of the Modular EV3 LEGO Mindstorms vehicle - the Trunk.
The goal of this robot is to teach students how to build modular robots. This first part is just one of the modules.
This is an LEGO Mindstorms EV3-G program for the motor and touch sensor that we use for the LEGO Catapult
