This video is part of a series where we show you how our Box Robot accomplished the M10 Steel Construction mission 10 out of 10 times. The attachment is a basic lever and all the 'heavy lifting' is done by the x-y movement of the Dominator robot. This mission is one of the hard missions, because the construction is big and heavy and this requires precise movement of the robot.

This program counts coins. It is meant to work with Scrooge McRobot. For it to count the coins correctly, you must change the coins border sizes to match the measurements of the coins that are being used.
We had a couple of minutes before starting another robot and we just came up with this robot. If you would like to build a Box Robot, but don't have enough parts this is a good construction that you could learn from. It has a frame. It has three motors. You can add attachments at the top.
We should multiply the error by a certain number and then add it to the steering of the LEGO Mindstorms Steering block. In this way, by changing the coefficient we change how much/fast should the proportional part influence the steering of the robot.
"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
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.
LEGO Mindstorms Robot Base for a high placed attachment for containing ping pong balls. It is interesting how the balance is achieved with such an attachment. It was only one of the version in a series of LEGO Mindstorms Robots for World Robotics Olympiad.
Advanced LEGO MINDSTORMS EV3 Construction. It has two rear motors and it could rotate the whole from part. It has 4 wheels and is kind of like unique in the Mindstorms world.
Building instructions are not very easy and you need LEGO Education Core and Extension Sets - 45544 and 45560.
Apart from being advanced, it is also quite fun to try to build.

Let's put everything that we have learned so far into practice. Let's make a spy robot!
The Gyro sensor can be positioned horizontally, vertically or at a random angle. Have you ever wonder what does the gyro detect when it is positioned vertically. This is the subject of this video tutorial for the LEGO Mindstorms EV3 Gyro Sensor.
In the first LEGO tutorial we started following a wall with the Ultrasonic Sensor. In this tutorial we would improve the program, remove the zig zag movement and make it very smooth.
As an extension to the previous video we talk about the Hi Technic Color Sensor again.
We are showing the first way we could position the motors on the robot construction. This seems to be challenging for many robot builders and that's why we are going to do it in a few different ways in the next few video tutorials from the series.
All worked as expected, up until know because the robot got lost. This happens when we turn right and the line does not continue to the right. Now the robot must somehow understand that it is "lost" and escape.
