For the FIRST LEGO League 2016-2017 Animal Allies we prepared an attachment for lifting the robot. The idea of the attachment is to show how you could lift the whole robot with a system of gear wheels, levers, and scissors constructions.
Built mainly from LEGO Mindstorms EV3 parts but could probably be constructed from NXT sets.
This time we stop on "Using the Right Senses" mission, or actually on how to solve the "Right Senses" mission without "Senses" (sensors). To achieve that we use the carabineer counstructed in one of the previous tutorials, of course after a small modification.
This is the oldest and most classic problem in the field of robotics. Shaft in an opening. Basically robotics and in improvement of many of the actuators is about improving the solutions to such problems. Let's see how we ca do this using a mission model from the FIRST LEGO League (FLL) competition.
The FIRST LEGO League Competition is divided in four categories. The Robot Design category is not as popular as the Robot Game, but still is 25% of the end result of a team. In this tutorial we will stop and make an overview of it.
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.
The NXT Competition robot was the first competition robot we designed. For most of the part in 2011-2012-2013 it was working really great. Than EV3 was released
A simple active attachment that could be added to the Box Robot Chassis.
Разполагахме с няколко минути преди да започнем да строим друг робот и ни хрумна идеята за този. Ако искате да построите Box робот, но нямате достатъчно части, това е една добра конструкция, с която може да се упражнявате. При нея има рамка и три мотора, като може да добавите и приставки.
Should the robot be with a Front Wheel Drive or a Rear Wheel Drive to make it more precise? The answer is - front wheel will probably give you better results, but the wheel drive is not the most important thing. In this video tutorial on the LEGO Mindstorms Robots, we will do a few experiments to discuss the influence of the wheel drive on the precision of the movement.
The LEGO Mindstorms EV3 set comes with two LARGE motors. But even though these motors look almost the same they are not quite the same. There are always some differences in their behaviour. If you have more than two motors, because you bought them or you won them somewhere at a competition, it is worth doing an experiment to find which pair of motors works best.
In this video tutorial we would discuss the M13. OBSERVATORY mission from the FIRST LEGO League robotics competition 2018-2019 Into Orbit. This is an easy mission. You can accomplish it by pushing the level with the robot. The challenge is that there is not enough space to move with the robot around the attachment. Let's discuss how we could achieve it.
The program that Nightbeast team use for their first Run in FLL Into Orbit Challange. In this run they solve two missions: SpaceTravel and Solar Panel .
Move the robot to the bring. Bring the flags up

These are instructions on how to build the:

The story goes like this. Two engineers meet at a bar (or on discord during the pandemic) discussing which robot to use for this year FIRST LEGO League 2020 Replay Solution and Review with explanations. They started their cameras, had a hot Carolina Reaper, had an argument, hugged each other and decided to build Gazon and use this new robot for the competition. So here it is. Small, 4 motors, 2 color sensors, stable, light.
This Python program is for controlling Gazon, LEGO Education SPIKE Prime competition robot to accomplish FIRST LEGO League (FLL) 2020 RePLAY Challenge mission 06 - Pull-Up Bar using Attachment for FLL 2020 Pull-Up bar mission
.
This is a 10 out of 10 tutorial demonstrating the accuracy of a Flip Attachment for the FIRST LEGO League 2020 Cell Phone Mission. The flip attachment flips a phone. Moves forward and flip it. This is a tricky business. It might not work. The trick is to approach the mission model from the right angle. In the tutorial you will see a demonstration and will learn how such a mission could be accomplished accurately with a LEGO Mindstorms Robot Inventor robot and attachment with gear wheels.
In this program we demonstrate how to program a SPIKE robot to align to а line with the aid of two color sensors. Make sure the line is big enough for the sensor to detect it. For this program to work, the sensors must be placed in front of the wheels.
This program was intended for and tested on the Gazon robot
