Following the Advance Light/Color sensors calibration for a minimum value for a single sensor tutorial, in this one, we continue with finding the maximum value detected by a sensor and storing this value in an array.
Construct two legs for both sides of the robot. The task for this video is to attach this two legs on both sides and to build a system of gears and axles that power those legs.
We dispay the speed of rotation of the wheels on the brick screen. We use the math blocks to do a proper calculations from rotation to radians per second. Knowing the speed, the radiuses and the mass of the wheels we find energy in Joules accumulated in the construction.
This is how to use the display block to show images with the EV3 software.
Let's make a program that moves the robot forward and then backward.
Explanation and demonstration of the big task for the lesson.
What is allowed and what is not when building without instructions.
Each palette contains programming blocks that share common purpose. We will cover most of them
This is a teacher's note about the math behind calculating gear ratios with for our lifting attachment. It math model we build in previous tutorials is not exactly correct and here is the explanation why.
A note why we give the challenge at the start of the lesson.
There are some things to be careful about when your students work with the brick.
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.
As an exercise try to implement the calibration of the minimum and maximum values for a single sensor.
Robots could do chores for us and they must consider the load of the cargo or the robot could be damaged.
Implement the program for array initialization.
Follow the video tutorials for initializing arrays and implement the program.
We encourage you to explore the software on your own.
Sometimes the answer that you get by calculating seems not to be right. Is it the calculation that is wrong. Probably it is not the calculation, but something is happening with the robot.
Let's make a competition - there is a pole that the robot must turn around and return home.
Our next robot is called CastorBot, because of the castor ball.
The task in this tutorial is to execute the program 10 times and to do it yourself. If you have your attachment then use it. If you have our attachment then use it. But execute the program 10 times and make sure that it works.
We will take a look at the EV3 motors and will go into details about them
Sometimes a good teacher needs a few tricks in his sleeve, so that he can surprise and entertain his students.
This video tutorial shows how the LEGO Mindstorms EV3 Handlebar Chopper Motorcycle robot works. See how fast it is.
We will demonstrate with a robot what the acceleration is and the effects of high and low acceleration.
This video tutorial contains a detailed explanation on how we accomplish the FIRST LEGO League 2018-2019 Into Orbit mission called M05. EXTRACTION. On every robotics competition we have the challenge to collect, carry and return to base a number of objects. It is just in different way every time.
Let us do a quick recap of the whole lifting mission and its solution
