Move tank block in Mindstorms EV3-G software.
There is the Move Tank programming block in the software. It allows us to set different power to each motor.
In real life, the same concept is used in cars, for example. The traction control systems apply different power to different wheels, so that the car is more stable on the road during turns or on slippery road.

Five Minute Bot
Building instructions for a LEGO Mindstorms EV3 Robot that we call the Five Minute Bot because it could be built in Five Minutes.
Note: If the robot is making inconsistent turns due to the floor, modify the castor wheel so it is placed further back in the construction. Thus the center of mass falls more over the tires and the turns are more consistent.

Inertia Bot - LEGO Mindstorms Robot with a large inertia cargo
There is a lot of physics and math involved when learning with LEGO Mindstorms EV3 robots. It is generally "difficult" to include them directly during classes because students are coming for "something funnier" and at the same time, they could be of different ages. But Inertia is a pretty common topic that is quite easy to introduce to students, especially with a robot.
The robot moves and stops. What will happen with the cargo when the robot stops? Naturally, the cargo will continue moving and this is dangerous. For how long, what would be the energy? All these are things that could be discussed with this robot.
The robot is not completely finished because you have to finish it and decide on the wheels to be used.

Shotgun - Sports Motorcycle with assistant wheels built with LEGO Mindstorms EV3
This one is also fast. It has assistant wheels, but only to keep the balance. It is built with LEGO Mindstorms EV3 sets with the use of one additional Medium Motor.
Join the course A robot a "day" keeps the questions awake where we will further discuss the motors, how to build them and what tasks to accomplish with them.

Polar Bear - LEGO Mindstorms EV3 Robot that looks like a polar bear
We love bears. These are great creatures. Do you know that the Polar Bear is the largest bear there is.
This robot was first constructed years ago for some of the first classes in LEGO Mindstorms Robotics that we held. It is quite challenging, but nevertheless very rewarding when completed and when you manage to program it to walk. Check it out.

Opening the RC Remote Control Car
The course is designed to be used with almost every remote controlled car. The process of opening the car will be different for different cars but there are basic principles that you could follow.

Name of the parts in a opened Remote Control car
Give it a name and you will have power over it. I learned this from an MIT professor. So let's give the part of the car names. Then we could refer to them. Talk to them. Change them. Do all kinds of things with them. Give it a name and you will have power over it.

MyBlock for controlling the Medium Motor by position.
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.

EV3-G experiment plotting the Gyro Sensor and the Current Power
The experiment contains a plot of the Curren Power of Motors B and C and the values of the Gyro Sensor when the robot is moving with a power of 100%. What you could see is that it is not actually moving with a power of 100% because the current power is about 75-80%.

Geldautomaat, a LEGO Mindstorms EV3 ATM robot
Geldautomaat, from German, means ATM.
This is the last robot from the 3.0 course book in the LEGO Mindstorms Curriculum. It uses a Touch Sensor to sense if there is a card inside. When touched, a Medium Motor starts spinning and pulls the card inside its chamber, where a Color Sensor reads the data from the card.
NOTE: There is a step, where you have to place the "credit card" inside. It may seem unnecessary and pointless, but otherwise, you will not have proper support for the next steps and the construction will crumble.

EV3-G MyBlock for moving the Boomer
The block has the following parameters from left to right:
- Degrees – the degrees the front wheels of the car will turn;
- Power – the power of the car;
- Limited/Unlimited – if the value is marked by a tick, the car will move for an unlimited period of time; if the value is marked by an x, the car will move for the specified number of rotations;
- Rotations – the number of rotations the car will make.
Attention! This block is made only for robots with two driving large motors on ports B and C and one steering medium motor on port A!
Detailed explanation of how to use this myBlock is written in the tutorial How to use the CarControl MyBlock.

EV3 Python Let's learn to read the clock
This project works with the Chronos - LEGO Mindstorms EV3 clock robot. It aims to teach you to read the clock by showing a randomly selected time and giving you 5 seconds to guess what it is. It then shows you the correct answer and returns to its starting position.
