• LEGO MINDSTORMS EV3

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.

Let's implement a more advanced program for this robot to learn how to use with motors in opposite directions - and this is to implement the Proportional Line Following algorithm.

We would see how both satellites work together on the World Robotics Olympiad competition. They must both follow different orbits and must cooperate for the mission to be accomplished.

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.

Remember the passive/active attachment separation that we are making at FLLCasts.com. This applies for all the attachments and in this Episode, we are looking at how to use a passive attachment.  

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

In this video tutorial we would look at the mission run for M06. SPACE STATION MODULES. The missions is to precisely push a mission model into an opening. In almost any FIRST LEGO League competition there are such missions. The tutorial contains only the mission run on the field. We accomplish a single mission. 

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.

The robot works on the field and decodes the different colours that represent the rows and the columns.

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?

After we have introduced a menu in the previous video, this video focuses on storing the values in an array. It presents a basic use of arrays.

If you get to a solution that is too complex you should always try to improve it. This is what we are doing here. Arriving at a solution for aligning to the wall that has become too complex.

Using the rack depends on the experience of the team. Based on this a different number of gear wheels and racks would be used.
