In this video tutorial we demonstrate the user of a quick 'pinless' attachment. As all pinless attachment it is not that they are completely pinless, but that they do not require the "click" of the pins that is often difficult to achieve in a quick pace environment as during FIRST LEGO League competition rounds.
In this video tutorial we look at Vertical Lift Attachments. The attachment, the root and the mission model are all build from LEGO MINDSTORMS Robot Inventor 51515 set. We've found that vertical lift attachments that could lift missions models vertically could be quite useful for FIRST LEGO League competitions. This attachment is one of the more complex attachments and some say it has an "eye opening" mechanism as you can learn so much from it. It uses gear wheels and two levers connected to those gear wheels to lift a part vertically.
Counting lines and stopping on the third is the subject of this video. It is important to know how to do this in order to conduct more than one experiment in STEM classes (if we consider that each line is an experiment)
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.
In this video tutorial we demonstrate an attachment that can accomplish Drop missions. A drop mission is when you have to move on the FIRST LEGO League field with the robot, reach a mission model, and drop a part in this mission model. First time we saw such missions I think was in FLL 2013. The attachment, the robot and the mission model could be build from a single LEGO MINDSTORMS Robot Inventor 51515 set. The mechanism for dropping works by releasing a lever when the attachment is pushed against the mission model. Check them out.
Positioning your MINDSTORM robot precisely on the FIRST LEGO League competition field is one of the first things you should learn while preparing. In this video tutorial, we will show three different attachments you could use when aligning to the walls of the competition table. We will show other ways and attachments in some of the next videos.
It all started with the famous 2017 mission for flipping a manhole and it was one of our favorite missions ever. Here in this tutorial we demonstrate the same principle of flipping a part from one side to the other. Sounds interesting, yes it is, yes it is.
Recap on the attachments, their purpose and how you should use them.
In this video we discuss part of the pinless attachments build by the ELM team. Without pinless attachment it is nearly impossible to achieve a good score at the FIRST LEGO League competition.
In this tutorial we demonstrate how a loops mission could be accomplished with a Push/Pull Attachment. The robot attachment could be adapted to other missions at FIRST LEGO League/World Robotics Olympiad and other robotics competitions that require push/pull. The principle is the same. The tutorial uses Luly, small LEGO Education SPIKE Prime competition robot with 3D building instructions as a robot base.
The program from part 3 should be refactored and improved to make it easier to understand and support. We extract most of the repeatable behaviours in a loop and this reduces the size of the program three times in terms of the number of blocks used.
This video tutorial reviews the EV3 Gyro Sensor and the HiTechnic Gyro Sensor for the LEGO Mindstorms NXT robotics Kit. We compare the two sensors and demonstrate them in action.
In this video we are showing how to use two light sensors to do basic aligning on a black line. This is always needed at the competitions. We also show an example for following a line with two sensors.
In this episode we continue from Episode 55 and we improve the durability and stability of the attachment for a LEGO Mindstorms EV3 robot. Many times attachments are not very stable which results in gaps between parts. The goal of the video is to give basic construction ideas.
This is where the confusion really comes. We are keeping the robot orientation straight while the robot moves, but at the end the, robot is not at the fiinal location that we would like it to be. The robot is still about 2-3 centimeters away after moving for about a meter.
Tasks for introduction on building robots.
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.
90-градусовото завъртане на робота е различно от 90-градусовото завъртане на мотора!
In this video tutorial we will show you three ways for making your robot stable on the field. We will present each one of them with their advantages and disadvantages - it's up to you to choose which one is the best for your case.
Cable management is very important on each competition. Cables could get in the way of attachments, levers, different wheels and so on. Brick accessibility is also very important. Do not forget that the brick should be charged from time to time and that you should also be able to access the buttons.
The way you move the robot is always imprecise. Don't TRY to fight with this. Programming motors for competitions like the FIRST LEGO League (FLL) or World Robotics Olympiad (WRO) is not very different from programming the motors in the STEM classes. But there are a few things you should have in mind.
This one is very special- an attachment that could lock itself on purpose while working.
The color sensors supports different modes of working. In this video we are working with the Reflected light, which is not actually the detected color. Most robotics sensors actually work with reflected light and you should definitely learn how to use this mode.
This tutorial in an animated demonstration of how a LEGO Education SPIKE Prime robot turns to the left and to the right. To download the program check out the courses in which the tutorial is used.
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 this video tutorial we experiment with different ways of solving the sports mission for throwing the ball. We show seven different LEGO MIndstorms EV3 and NXT robot constructions and attachements. Most of the techniques could be applied for any mission involving throwing a ball or an object.
You need to pull. And also catch. You need a carabiner. We have done a number of videos on carabiners and this is one of the ideas for the FIRST LEGO League 2015 Trash Trek competition.
