„Box“ робот 2 Рамка
Рамка за добавянето на приставки към робота. Когато използвате приставка, добавянето и свалянето на приставки без пинове става много бързо и лесно. Също така може да махнете и цялата рамка.
В рамката са използвани части от ЛЕГО Mindstorms EV3.

Box Robot Active Attachment for heavy lifting
When you need a LEGO robot attachment to lift heavy things on the competition field. Probably at FIRST LEGO League or World Robotics Olympiad. This attachment uses 4-5 gear wheels to lift a heavy object.
Build with LEGO Mindstorms EV3 parts.

Box Robot passive attachment
No need for all attachments to be powered by motors and to include gears. It's sometimes possible to use a simple robot attachment to collect objects. Such attachments we call passive and this one is an example for the Box Robot Chassis.
Build with LEGO Mindstorms EV3

Box Robot Two Left Side attachment with locking
This robot attachment shows you how to limit the rotation of a lever. It uses two gear wheels to transfer the motion on 90 degrees.
It could be built with LEGO Mindstorms EV3 and NXT versions. Most of the time during competitions like FIRST LEGO League and World Robotics Olympiad you need a lever for just a limited motion

Box Robot Two Central Axle Attachment
The central axle of the robot is most of the time the most important. The robot moves forward and does things with this axle. It is important to learn to you could extend such axles, and change the level and position of the extensions.
This is a LEGO Mindstorms EV3/NXT robot attachment.

Box Robot Two Push/Pull Attachment with a Rack
Robot attachment that shows you how a circular motion could be transferred to linear by using a gear and a rack. The final motion is for pushing and pulling things.
The attachment could be built from LEGO Mindstorms EV3 and NXT parts.

How to calibrate more than one LEGO Mindstorms EV3 Light/Color sensors at a time
Would you like to resolve all the problems with the light/color sensors that you have? And to make all of them work in a predictable, stable way even when using more than one MINDSTORMS colour sensors.
When using Color sensors it is important to calibrate them depending on the light conditions in your venue. In this way, the calibrated sensor will show values between 0 and 100 independent of the light conditions. But using the default EV3 colour calibration available in the colour sensor block could lead to unpredicted problems that are difficult to track and resolved especially when used with multiple Color sensors. So in this series of tutorial we implement the calibration ourselves discussing the principles of colour sensor calibration.

Initialize an array for Advanced Light/Color sensors calibration
"Array initialization" is the first step in every program that involves Arrays. This applies to most programming languages and for EV3-G it is a must.
In this tutorial, we would show you how to initialize the array and how to extract this logic in a new block

Advanced Light/Color sensors calibration for a minimum value for a single sensor
In this tutorial, we would implement a program that finds the minimum and maximum value detected by the sensor and stores this two values in an array.

Advanced Light/Color sensors calibration for more than one sensor
In the course section for Advance Sensor Calibration we previously showed you how to find the minimum and maximum value for a single LEGO Mindstorms Color Sensor and to store this value in an array. The program was implemented with the EV3-G software. In this tutorial we are going to find the Min and Max for all the four sensors and to store all the 8 values in an array.

Building an example program using calibrated value for Light/Color EV3 Sensor
Many times we just upload blocks and leave it up to you to use it. In this tutorial, I would like to show you how to use the implemented blocks. How to import them into the EV3-G software. How to see them in the palette. How to drag and drop them to build a working program.
