Your lesson guide

Objective

Work toward the lesson goal: Controlled Path. Use the directions and success criteria in the activity below.

Materials

For the online work: a browser and your engineering notebook. Follow the activity’s materials list for any physical build, and get teacher approval before using equipment.

Plan your time

Suggested work block: 45–60 minutes. Physical builds and projects may span several classes; follow your teacher’s schedule.

Lesson Overview

In this lesson, you will explore how a robotic arm follows a controlled path. Instead of moving randomly, the arm follows a planned sequence that can be tested, adjusted, and repeated.

Notes

  • A controlled path is made from multiple movement commands in a specific order.
  • Small coordinate changes can create large differences in the final path.
  • The same sequence should run consistently if the setup is unchanged.
  • Test the path slowly first and check for unsafe or unexpected movement.
  • Comments should explain the purpose of major sections of the path.

Build your lesson report

Checkpoint: is your evidence ready?
  • Check calculations, units, labels, and measurements against the activity requirements.
  • Record what actually happened, including unexpected results.
  • Explain what you changed and why; attach required drawings, photos, CAD, or code in your classroom assignment.

Submit the evidence specified in the activity and your classroom assignment. The report below collects your notes, calculations, observations, and reflections; attach any required drawings, photos, CAD, or code separately.

A PDF download is not a submission. Review it, then upload it and any required attachments through your classroom assignment system.
