I am new to this and I need some help with the moveabsolute block which is described in Chapter 16 of Daniele Benedetelli's book. In figure 16 - 2 he describes the block and here is my problem: I cannot find the first symbol all the way to the left in figure 16-2 . I believe it is called "connection " or "connector" . Right of that symbol is the symbol "speed" followed "degree" and "brake"

Where do I find this symbol "connection or connector"? Where do I find this block or do I have to assemble it myself ? If I have to assemble that block myself - how do I do that ?

    Is there any chance you could include a picture of the figure in question?

Figure 16-2

The Lego Mindstorms EV3 Laboratory by Daniele Benedettelli

  1. Open / create the EV3 program for the T-Rex
  2. add the motor rotation, math and large motor blocks to your program. Don't search for the first block.
  3. Select the 3 blocks you just added.
  4. Select My Block Builder under tools menu. You get a new window
  5. Give the block a name.
  6. In the top half of the screen click the button add or edit parameters 4 times (4 Connections)
  7. On the parameter setup tab you must changes the values according the book.
  8. Under Parameter Icons tab you can add some icons to the different parameters.
  9. When finished select the finish button

Now the My Block will be created and opened. Here you see that the first connection block is added. Now you can add the different signal lines.

In your main / used program the 3 blocks are replaced by your My Block

  • Loost, could you explain a little more detailed what you mean by "...add the different blocks you want in your MyBlock to the editing screen, select them" My problem that I cannot find that symbol "connection, or connector " which is displayed in figure 16 -2
