LEGO MINDSTORMS EV3

Importance of the construction balance on the LEGO Mindstorms robot movement
The balance of the construction of the robot has a great influence on how it will move. This is especially true if you would like to move in a straight line. If the robot is slightly heavier on the right it will move to the right. Here we have two robots - a Five Minute robot and a Box Robot and we will discuss the differences in the constructions and why the box robot is much better than the Five Minute even though it is using the same parts.

Rubber bands - LEGO robot attachment that triggers with a motor
The robot attachment build in this tutorial gives an idea on how to release a rubber band at a specific moment using a motor. It's a simple, but yet powerful technique on using rubber bands.

Turtle Program
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

Teacher's Note: What should you explain to the students about Current Power
The first task today shows students how motors generate power. If students are older, you can give them more information about electricity and current. In the general case, however, it is enough to say that the faster the motor rotates, the more power it generates. This can be seen from the current power option of the wait and switch blocks. You can show students this option or leave them search for it in lesson 1.
The next task is to download a block and insert it in a program. This block reads the power from port A and transmits it to port D. The aim of the exercise is to highlight the difference between wheels. As T-Rex has larger wheels, it moves faster.
The following two tasks show that even when the wheels of the robot are larger, a lot of power is lost when the two motors are connected directly. You can explain that this is the principle due to which an eternal engine cannot be built.

FLL 2017: Attachment The Manhole Cover (08th) Mission
We have to admit. This is quite an interesting missions. There is a Manhole cover and it must be turned upside down. Well, the robot must turn it. Again LEGO Box Robot Three With Large Wheels and Thee light sensors and one Gyro is used as a base for the Robot.
