Lesson 2: Using the Electromagnet
-
Once the VR Robot reaches the first blue disk, the VR Robot must boost the Electromagnet using the [Energize Electromagnet] block. Drag the [Energize Electromagnet] block beneath the second comment.
For Your Information
The [Energize Electromagnet] block has two different modes: ‘boost’ and ‘drop.’ ‘Boost’ turns on the Electromagnet and creates the electromagnetic field needed to attract a disk to the Electromagnet.
‘Drop’ reverses the current of the Electromagnet and releases any disks being held by the Electromagnet.
Using Switch Blocks
This is the Switch [Energize electromagnet] block.
You can change the parameter of the Switch [Energize electromagnet] block by replacing "BOOST" with the word "DROP" in the parentheses. Be sure to use all capital letters when changing the parameter.
-
Next, the VR Robot will drive in reverse back to the starting point with the blue disk. Place a [Drive for] block beneath the third comment. Set the [Drive for] block parameters to reverse 750 millimeters (mm).
-
Once inside the blue goal, the VR Robot will need to release the blue disk. Add a [Energize Electromagnet] block beneath the fourth comment, and set to ‘drop.’
-
Open the Disk Mover Playground if it is not already open and run the project.
-
The VR Robot picks up the first blue disk by energizing the Electromagnet, then drives in reverse back to the blue goal and drops the blue disk.
