Unpacking the VEX EDR set and learning the names of the different parts included in the set
Part four of the Catapult series is again about loading the catapult automatically but this time using EV3 brick, motor and sensor. We use a gear system with a medium complexity along with a "standard clutch" available in the LEGO Mindstorms EV3 kits. As a result, at the end of the video, the Catapult loads and fires automatically.
Why we change the robots all the time and what to observe in each new robot.
What is allowed and what is not when building without instructions.
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.
In the video we improve on the robotics mechanism for pushing the different blocks out of the robot container. We continue from the previous video.
Attach an axle to the front of the robot. Find a similar one, or modify the FTC Tetrix robot to accommodate the new axle.
In this robotics tutorial, we give a few notes for the teacher about adding an axle to the front of the FTC robot and attaching a plastic plate to this axle to make the robot collect balls.
Gears could be a powerful tool for those who know how to use them appropriately. In this episode we introduce some of the basic terms and concepts behind using gears in your construction.
Based on feedback from many of you in this episode I would like to show you how to build an active attachment that changes the orientation of a gear wheel placed vertically to a gear wheel placed horizontally. This attachment could be used in competitions and shows a basic principle of changing the orientation. All attachments could follow the same principle.
How do you lift heavy objects with an attachment? In this episode we show a simple, interesting, but yet not very popular way to lift something heavy with and LEGO Mindstorms EV3 robot and without gears and motors as attachment. As a specific example we are using the Strength Exercise mission from the FIRST LEGO League 2012 competition.
With this series of videos we are looking at FIRST LEGO League 2013 Nature's Fury competition and we are building a robot for accomplishing some of the mission. It would be a tutorial with at least four parts and we are building a complex attachment that could catch, lift and release different parts with only one motor and rubber bands. Not one, not two, but three movements with only one motor.
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.
This tutorial is about how to follow a wall with an ultrasonic sensor. The example is with a border from a FIRST LEGO League (FLL) competition, but could also easily be applied to other competitions and problems.
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.
