In this Play section, now that we have explored the difference between linear and joint movement, we will use variables to code the arm on the Workcell to make linear movements along the x and y-axis. You will create a project that will orient the arm to a beginning location and then draw a square. This is important because this motion is an introduction to how the arm moves when picking up and dropping objects, that will be explored in later Labs.

In order to code the arm to draw a square, you first need to build the 'Lab 5- Variables' project.

In VEXcode V5, follow the steps in this video to open the 'Arm Display Position' example project, input your mastering values, adjust the tool, name, and then save the project as 'Lab 5- Variables.' 

Ensure you are using your mastering values, and not the ones displayed in this video.
