In this Play section, groups will be introduced to the V5 Electromagnet on the arm of the Workcell. They will then create a project where the arm uses the electromagnet to pick up and drop off a red disk in a specific location.

The UI on the Brain will display four colored boxes (white, red, green, and blue). Each color corresponds to a particular movement of the arm on the Workcell. The white box will move the arm to the disk pick up location and each of the colored boxes will move the arm to that colored disk's drop off location. For this Play section, groups will only use the red and white colored boxes. In the Rethink challenge, groups will code the arm to pick up and sort all three colored disks (red, green, and blue).

Groups will complete the activity by successfully moving the red disk to its drop off location using the UI on the Brain’s screen.

What the Teacher Will Do:

• Bring students together for whole-class instruction.
• Introduce the Lab to the students.

  • Tell students now that they have explored coding the arm to move to different points on the Workcell, they will create a project to pick up and drop off disks in specific locations.

  • They will first display the (x, y, z) coordinates on the Brain’s screen to find the locations that the arm will need to move to in order to pick up and drop off the disk. Then, they will use these locations to explore how to trigger behaviors of the arm, by building a project that uses a User Interface (UI) on the Brain. 

  • Explain to students that the UI on the Brain will display four colored boxes (white, red, green, and blue) and that each box corresponds to a specific movement of the arm.

• Tell students that in their groups, they will create the 'Lab 7- Manual Move' project in VEXcode V5. This project will display x, y, and z-coordinates on the Brain, and then code the arm to pick up and move a red disk.

What the Teacher Will Do:

• Keep students together for a whole-class discussion about the activity.
• Instruct students that they will be working together in their groups to follow the steps on this page.
• Ensure each group of students has their devices to run VEXcode V5 and to view this page in the Lab.
• Tell students to check in with you once they have completed the steps on this page.
• Break students off to work within their groups. Walk around the room as students are working to answer any questions if they arise.
• As groups check in, ensure they have built their project correctly before moving on. Guidance for the check in is provided in a Teacher Toolbox at the bottom of this page.

For more information about how to facilitate this activity, go to the V5 Workcell Educator Certification.

• Saving a VEXcode V5 project may look different depending on the device that your students are using. For more information on how to save on a specific devices, view the Save a Blocks Project (iPad, Chromebook, Windows, macOS) articles from the Knowledge Base.
• For more information on opening example projects, view this article from the Knowledge Base.
• Remind students that their mastering values will be different than the one shown in the video. Students should be using their values, and not the values from the video.
• For additional tips, go to the V5 Workcell Educator Certification. 

  Review the following with the group during their check in:

• Ensure their project contains the correct mastering values and the tool plate is set to 'electromagnet.'
  
• Check that groups have Points 1, 2, and 3 recorded in their engineering notebook. 
  • Students may need to adjust the location values multiple times when testing to obtain a more accurate location.
  • Remind students that the z-coordinate value should raise the arm up enough to not collide with any standoffs, especially when transporting a disk.
