Precision Driving, Sensors & Debugging

11 Structured Editable Lessons | Designed for 45-Minute Class Periods

This unit builds directly on introductory movement coding and guides students into precision control, sensor logic, debugging, and engineering decision-making.

Designed as Weeks 3–4 in a structured robotics progression, this resource includes 11 lessons, each intentionally planned for a 45-minute class period.

Students move beyond basic movement programs and begin coding robots that respond to their environment using touch, color, distance, motor rotation, and gyro sensors.

There is no filler and no rushed instruction — each lesson introduces or applies a core robotics concept needed before advancing to more complex programming.

What this unit covers

Over the course of 11 class sessions, students learn:

• Precision turning and movement control
• Conditional logic with sensors
• Continuous checking using Forever loops
• Threshold values and common logic mistakes
• Debugging broken sensor programs
• Comparing sensor choices and engineering tradeoffs
• Evaluating multiple coding solutions for the same task
  

This 11-lesson unit includes:

✔ LEGO SPIKE Prime Turning Challenge
✔ Analyze the Movement
✔ Sensor Scenarios (Unplugged)
✔ 5 Intermediate Read the Code worksheets
✔ Touch Sensor Coding Activity
✔ Sensor Logic Errors – Debugging Worksheet
✔ When Is Each Sensor the Best Choice?

All lessons are structured for one full 45-minute class period and include student worksheets and teacher guidance where applicable.

Pacing & Structure

• 11 total lessons
• Each lesson = one 45-minute class period
• Designed for approximately 2–2.5 weeks of instruction
• Follows the Intro to Coding & Movement unit
  

How this unit fits into a larger robotics sequence

This unit is designed as the next step in a multi-unit LEGO SPIKE Prime robotics progression. It prepares students for advanced logic, multi-sensor programs, and project-based challenges.

All resources included in this bundle are also available individually. If you plan to purchase the bundle, you do not need to buy the individual lessons separately.

Teaching Guide

This unit is designed to move students from understanding movement-based programming to confidently using sensors to control robot behavior.

Suggested Implementation:

• Begin with precision movement and turning challenges to reinforce control and accuracy.
• Use the “Analyze the Movement” and “Sensor Scenarios” lessons to strengthen reasoning before introducing new coding structures.
• Teach the Intermediate Read the Code lessons sequentially. These build progressively from simple conditional checks to more complex sensor logic.
• Introduce the Touch Sensor Coding Activity after students are comfortable predicting sensor behavior. This lesson allows students to write and test their own working sensor program.
• Follow with the Sensor Logic Errors worksheet to reinforce debugging skills and help students identify common logic mistakes.
• Conclude with the Sensor Comparison lesson to guide students in evaluating engineering tradeoffs and choosing the best sensor for a task.
  

Throughout the unit, emphasize prediction before testing and reflection after testing. Encourage students to explain why a robot behaved a certain way, not just what it did.

This unit works well in classrooms where robots are shared, as many activities include structured thinking and discussion alongside hands-on programming.
