It's a box! It's a robot! It's a box robot. Box robots are very popular on different robotics competitions involving LEGO Mindstorms like the FIRST LEGO League or World Robotics Olympiad. Let's start with a brief introduction and continue in the next videos with explanation on the features of the robot and why such robots are frequently used.
Here we start with a second box robot that we would like to build. It is in a way improvement to the first robot and we would take a look at its features.
In this last part of the tutorial we actually lift the rocket modules and prepare them for lauch. First we have to collect them in the right order and them somehow lift them.
Football with robots could be quite fun. Football with LEGO Mindstorms robots is one of the popular categories for competitions with LEGO Mindstorms Robots.
We are working on the World Robotics Olympiad (WRO) 2013 competition and its elementary part. The series will introduce three different concepts and this would be Arrays, Menus and Counting different lines. In the video you will see the robot working as it is in the final stage.
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.
Moving in a grid of objects. That's the large challenge of the World Robotics Olympiad 2015 Junior-High 2015. In this video we would build a robot that can collect the boxes (treasures). The robot would also be able to move around the treasures.
Starting with the World Robotics Olympiad 2014 Junior-High challenge we first catch the object on our path. We discuss a good mechanism for catching and lifting balls that can do two movements with one motor.
This tutorial demonstrates how a robot could align to a black line. The code for the program is available in the course. Aligning to black lines is popular at robotics competitions like FIRST LEGO League as it is the primary way to know where you are on the field and to develop a program that is reproducible. The attachment uses Luly, a small LEGO Education SPIKE Prime competition robot with 3D building instructions as a robot base.
Inertia triggered attachments does no require the use of a motor. Let the inertia do all the work. These kinds of attachments are very useful at robotics competitions like FIRST LEGO League and World Robot Olympiad. The robot moves, the attachment falls and grabs the ball. The attachment uses Luly, a small LEGO Education SPIKE Prime competition robot with 3D building instructions as a robot base.
Next robot construction for holding and releasing balls from this container. In this video we discuss the improvements and how to use the chains to release one ball at a time.
In this episode we do a full run of the mission for collecting a single treasure before going into explanation on how we have programmed the robot.
Collect the humans and clear them from the rocket launching region. This is rather straightforward as a task, but it requires a little bit of thinking if you want to do it without manipulators.
Improving the construction for the World Robotics Olympiad missions. The improvement is in the position of the sensor and the size of the balls container.
One of the simplest tricks in the game - move, complete the mission and leave the attachment with the mission model. You don't have to return the attachment to the base. On some competitions there might be penalties, but it might be worth it, as you save time to complete another mission. This works especially well with large attachments.. The attachment uses Luly, a small LEGO Education SPIKE Prime competition robot with 3D building instructions as a robot base.
This tutorial demonstrates how a LEGO Education SPIKE Prime robot could stop when it reaches a wall. FIRST LEGO League competitions are held on tables that have border and it is sometimes useful to use the Ultrasonic sensor to detect the border and stop close to the border. The attachment uses Luly, a small LEGO Education SPIKE Prime competition robot with 3D building instructions as a robot base.
