ADM Activity 2.1.4

Conditionals and Loops

Use programming logic to make decisions, repeat actions, and control automated processes.

Lesson Overview

You will use programming logic to make decisions, repeat actions, and control an automated sorting process. This example combines repeated pickup movement, optical sensor input, conditional decisions, and stacked placement locations.

Notes

This lesson focuses on using loops and conditionals to control an automated sorting process.
The loop repeats the pickup, sensing, and placement process for multiple objects.
The optical sensor hue value is used to decide which bin or stack location receives the part.
zGreen and zRed track stack height so sorted parts can be placed in layers.
Final submitted code must include meaningful comments explaining the loop, sensor decision, and placement logic.
