Display Array Blocks
This is an EV3-G block for displaying the values of array cells in an EV3-G program.
Project
The project contains two programs, which are demos of the blocks for displaying Boolean and numeric arrays.
Two blocks
You can import that blocks in your programs. They are designed to show you in real time what are the values in your array and let you go to the next bit of your program. The blocks operate with the UP and DOWN brick buttons to iterate through the array. And the CENTER brick button to advance to the program.
The blocks are very useful for students to show them in real time what values they have stored in their arrays. Because there is no easy way to see real-time what the values are in the array even if it contains only a few elements.
The block shows you how many elements there are in the arrays and the values in the following way:
For Numeric
For Boolean

The robot is not at the right position at the end of the straight movement?
This is where the confusion really comes. We are keeping the robot orientation straight while the robot moves, but at the end the, robot is not at the fiinal location that we would like it to be. The robot is still about 2-3 centimeters away after moving for about a meter.

FLL 2020 Inventor attachment for the Step Counter mission
This is a FIRST LEGO League robot attachment for the Step Counter mission from the 2020 RePlay competition. It is a pinless attachment that is optional and could be used on the robot or we can accomplish the mission without the attachment. It is better to use the attachment as this will give us a more smooth and accurate movement of the robot.

How to automatically detach an attachment from LEGO Mindstorms. Example with Robot Inventor
This video tutorial is about a detachable attachment. In various FIRST LEGO League competitions there are missions that could be accomplished with an attachment and when you accomplish the mission you must somehow leave the attachment along with the mission model. Probably as a support - most of the time it is as a support. But we've seen some pretty powerful concepts that include things like leaving a clock mechanism that will continue to work for 30 seconds accomplishing the mission.
