• LEGO MINDSTORMS

As an extension to the previous video we talk about the Hi Technic Color Sensor again.

Build a similar mechanism to this one. Similar, but for your robot. This is the task for you. Try, give yourself half and hour or even an hour.

Do it yourself, fix the errors in the construction of the EasyBot

Overview of what is going to happen in module 3

This video lesson shows a very interesting specific example on how to use the LEGO Mindstorms EV3 Ultrasonic Sensor. The sensor detects if the catapult is loaded or if we have just fired an element. At the end of the lesson I also offer an interesting challenge that you could use in your classroom or at home.

Unplug one of the cables and observe what the robot does.

Connect the attachment to the box robot and find the correct number of rotations of the middle motor that would bring the robot up and forward and would attach it to the mission model.

The challenge is to make the robot move back and forth with ever decreasing distance.

Vision is still one of the very few fields where a human being could outsmart a computer. Still. Colour/Light sensors are the cornerstones of implementing a smart LEGO Mindstorms robot that could at least partially do "vision". In this video tutorial, we are using the robotics sensor to detect loading and unloading of the catapult.

One of the students' favorite LEGO Mindstorms robots. Have fun with Iqazator, moving over all kinds of obstacles as a real millitary tank machine. 

Introducing three main concepts - Energy, Inertia Moment and Angular Velocity. We describe what is the moment of Inertia, how do we calculate it and how do we measure it?

We will demonstrate how to connect the brick and the motors by using cables correctly and reliably.

Overview of what is going to happen that part of the lessons.

What is the end result? - have the attached on the mission model. What is the mechanism the would make the robot hang on the mission model.

This video tutorial shows how the LEGO Mindstorms EV3 Ninja Motorcycle robot works. It's a nice demonstration with the robot moving forward, backward, and slightly to the left and right. 

The Telephone game is played with 2 or more robots and is extremely funny. Each robot has a color wheel that can be rotated through the medium motor and a color sensor. The first robot on the left rotates the color wheel to a random color. The second robot must detect the color on the wheel and rotate its color wheel to this color. The third detects the color wheel of the second and so on. 

It is described in details in Lesson 4 of Level C2. Cooperation

If you look at the properties of the move block and the motor block LEGO Mindstorms NXT, you will see that they have much in common. Still they have several differences. You should be aware of these differences in order to choose the appropriate block for your needs.

Devi is a stubborn robot. No mater how many times you press the button, it will press the button last. It if you press again, it will press again. Sometimes it will rotate and speak, but will again press the button, and will continue pressing until the end of times. 

Use any blocks that you wish to solve the following task.

Here is the task for adding a beam on both sides of every gear wheel in your attachment.

Experiment with changing the orientation and direction of gear wheels. Here are part of the tasks that you should complete before moving forward with the course.

So far we know how to make a turn in an arc, just like the real cars do.
Today we will see what other options our robots have for turning.

Explanation and demonstration of the big task for the lesson.

The important task before the solution. If you haven't done it already, then attach a new axle at the front of the robot and extend the construction with gear wheels and axles to reach the two legs at the two sides of the robot. 

In this episode I will show you how to program the touch sensor part of the LEGO Mindstorms education robotics sets. I have given answers to questions like - how the touch sensor works or how you can use it.

We encourage you to explore the software on your own.

Robots could do chores for us and they must consider the load of the cargo or the robot could be damaged.
