• LEGO MINDSTORMS EV3

Let's explain the problem of just waiting for the Gyro sensor to detect an angle and think of why the robotics systems work like that.

This robot has a color sensor and this sensor is used for following lines. Additional Mindstorms EV3 sensors could be place on the robot, like a Gyro sensor or a second Color sensor.

One of the very good things about box robots is that you could easily align with them both to the front, to the back or to the rear sides. This aligning is helpful for FIRST LEGO League, World Robotics Olympiad or other robotics competitions with LEGO Mindstorms EV3/NXT robots. 

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. 

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. 

This robot could quite possibly be build from a single EV3 core and EV3 resource sets. It uses fewer parts and only three motors. There are additional parts that could be skipped when building the robot and we have added these parts only as to make the construction more complete. 

One more example for an active attachment with a system of gear wheels. This time the system is constructed so that the attachment could lift heavy objects. 

This is a third example for adding an active attachment. This third attachment is now connected to the wheel at the front of the robot. Again, the attachment could be easily extended. 

Second active pinless attachment for the robot construction. It is placed in the top/right corner of the robot and includes an interesting gear system for transferring the power. The attachment is suitable for complete rotations.

This is the first Active Pinless Attachment for the Box competition robot. The attachment is placed on the top of the robot and is controlled by one of the motors. 

Without the use of any motor, you can still accomplish a number of missions using passive attachments. You can still pull/push on different levers using only a beam or two connected to the frame.

We should how to build a frame that could hold the attachments for specific competition missions. This frame is added in a pinless manner. This means very fast and easy without any glitches of the pins.

In this video we discuss how do we transfer power from the motors that are "inside the robot box" to the gear wheels that are "outside the robot box". 

In this episode we look at the way this robot is balanced. A well-balanced robot could handle heavier attachments without losing track of its position on the robotics competition field. 

In this video we look at the way this robot uses the LEGO Mindstorms EV3 motors. How are they attached and the what the rotation of the motor is transferred to the attachments.

This video discusses the fact the robot requires a few more parts that are available in the LEGO Mindstorms EV3 robotics sets. We have a number of other constructions that require less parts, but for this particular robot construction we have decided to go beyond the standard sets, cheaply buy a few more parts and build a whole box robot with them. 

Sometimes robot builders are so overwhelmed with the process of constructing a robot that they forget two very important parts. The brick should be accessible and the cables should not get in the way. These are referred by us as Brick Accessibility and Cable Management.    

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.

After we have introduced a menu in the previous video, this video focuses on storing the values in an array. It presents a basic use of arrays.

The challenge for this video is to program a menu that is controlled from the LEGO Mindstorms EV3 brick screen.
