The Gyro sensor in LEGO Mindstorms EV3 sets is new for the sets and we answer basic questions about its usage. The sensor detect when the whole constructions turns at a particular angle, but there are a number of gotchas in using it.
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.
Given the large number of gear wheels and axles in each EV3 and NXT sets there are many possibilities for building gear mechanisms. We are developing something like a gear box that has different axles that could all turn in different directions.
Probably the robot I like the most from this series of five robots. See the video to understand why and what is interesting and special about this robot.
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.
We list the number of decisions that the robot is making while following the line. Then, we group them and decide on the number of sensors to be used.
In this video we look at the robotics mechanism for dropping the different blocks into the different region on the World Robotics Olympiad 2013 field.
With the shape of a box it is very easy to align this robot to different wall and to add very stable pinless attachments to it. The goal of the video is to discuss this feature of this particular robot construction.
With the EV3 Mindstorms set you receive three motors. Two are large and one is medium. These three motors could be used in different configurations and in this video we show how to use the motors on the second box robot for competitions that we build.
Where should you lift the robot? Especially if you don`t have the mission model that we are using
Here is our solution for preventing torsion and bending of the LEGO Mindstorms EV3 axles.
Let us do a quick recap of the whole lifting mission and its solution
In the previous video, we found the correct answer for our task and it is 18.75, or is it?
The length of the lever has a certain effect when hitting the ball. In this tutorial, I would like to discuss what it's the effect.
