Programs

This program is for Susan and Mark - a LEGO Mindstorms EV3 T-Rex chasing a car. The program makes the T-Rex wait for the car to reach a certain speed, and then attack it. This is made to resemble the T-Rex's said inability to see slow moving things. The goal of the program is to get the car's cable to stretch, while moving it by hand, when its wheels are turning and without the T-Rex noticing. The detection is made using the current power option on the motor rotation sensor.

This is a program for the Sebastian crab robot. It makes the robot walk, but also keeps track of where its legs are. It makes those who overrun the others to stop and wait for them. 

This program is for Cardiidae - a LEGO Mindstorms EV3 Clam robot. It provides a solution for the final tasks in Lesson 1, level D1. It makes the clam robot detect when it is being opened and then to close itself.

A program, that makes the Turtle  follow a designated course and get back to it, even if it's been manually rotated. It also hides in its shell when it sees anything close to it.

Careful: Gyro Sensor port in this program is port 3. Check your cables when you run this program.

NOTE: The program contains my blocks, that will appear broken if you use version before 1.3.0 of the EV3 Mindstorms Software

A collection of MyBlocks, that help you use the Turtle robot. The MyBlocks used are the following:
FollowCourse: Makes the turtle rotate, until it reaches the course it uses. If it's already on it, this MyBlock makes the turtle go forward. It uses the power you set it on.
PickNewCourse: Makes the turtle pick a new course.
HideInShell: Makes the turtle hide in its shell for the designated amount of seconds.
CurrentAndDesiredCourse: Displays the Current course and the course it wants on the display of the robot.

Careful: Gyro Sensor port in this program is port 3. Check your cables when you run this program.

NOTE: The program contains my blocks, that will appear broken if you use any version before 1.3.0 of the EV3 Mindstorms Software

A program for one of the scariest robots ever - Mantissa.

This is a program for communicating with LEGO Mindstorms Bluetooth between two bricks. The goal of the program is to control one of the bricks with another brick. The controller has two touch sensors that control the direction and two buttons on the brick itself that control the power. 

The control brick has two motors attached that are controlled. 

The goal of this program is to be used as an example of how to use the EV3-G Bluetooth. Yes, it requires two bricks, but most of the schools have two bricks and could test the program. 

This is an EV3-G block for displaying the values of array cells in an EV3-G program.

Project

The project contains two programs, which are demos of the blocks for displaying Boolean and numeric arrays.

Two blocks

You can import that blocks in your programs. They are designed to show you in real time what are the values in your array and let you go to the next bit of your program. The blocks operate with the UP and DOWN brick buttons to iterate through the array. And the CENTER brick button to advance to the program.

The blocks are very useful for students to show them in real time what values they have stored in their arrays. Because there is no easy way to see real-time what the values are in the array even if it contains only a few elements.

The block shows you how many elements there are in the arrays and the values in the following way:

For Numeric

For Boolean

Using the On for degrees (rotations) option of the the Medium Motor Move Block you program the motor to rotate for the given number of degrees. However, sometimes is useful to program the motor to go to a given position, instead. To achieve that you can use this block. It takes the start position of the motor as 0 degrees. Then when you run the block with given number of degrees it just rotates the motor to that position. For exaple if your current position is -20 degrees and you run the block with 30 degrees, the motor will rotate for 50 degrees. But if your current position is 10 degrees the same program will rotate the motor for 20 degrees.
