Tetrix Robotics Basics

---

Lesson Overview

Year Group: Year 10
Subject: Technology
Unit: Beginner Tetrix Robotics
Lesson Title: Introduction to Tetrix Robotics
Curriculum Area: KS4 Design and Technology
Focus: Systems and Control (Robotics and Automated Systems)

This lesson introduces students to Tetrix robotics as the foundation for designing and building robotic solutions. By the end of the session, students will have a solid understanding of the parts, tools, and basic functions of Tetrix robotics, as outlined in UK standards for the development of technical knowledge and engineering principles.

Lesson Objectives

Students will:

1. Identify key Tetrix components and their functions (aligned to KS4 DT Curriculum: Systems and Control).
2. Practise safe handling of tools and materials used in robotics assembly.
3. Explore applications of robotics in real-world problem-solving.
4. Reflect on how collaboration and problem-solving are integral to robotics.

Lesson Structure (60 minutes)

1. Starter Activity (10 minutes)

Objective: Get students thinking critically about robotics in everyday life.

• Activity: Project images of various robotic systems (e.g., robotic arms in industry, autonomous vehicles, hospital robots). Facilitate a brief discussion:
  • "Where do we encounter robots today?"
  • "What problems might they solve?"
  • "What challenges could arise when designing these robots?"
• Outcome: Students begin making connections between Tetrix robotics and real-world applications.

2. Introduction to Tetrix Robotics (15 minutes)

Objective: Provide students with foundational knowledge of Tetrix robotics.

• Presentation: Use physical examples of Tetrix components, such as parts, motors, controllers, and sensors. Explain their functions.
  • Key vocabulary: Servo motor, chassis, gears, DC motor, sensors, structural beams, motor controllers.
  • Highlight linkage to KS4 Design and Technology Curriculum: Discuss how Tetrix systems integrate mechanical principles and programming - both vital for GCSE learning goals.
• Interactive Demonstration: Begin with a simple motorised assembly (pre-built by the teacher). Show how the motor moves and ask, "What do you think makes this move?" Lead into discussion on motors and controllers.

Teacher Tip: Make this tactile. Pass parts around the room for students to touch and examine up-close to spark curiosity.

3. Hands-on Exploration (25 minutes)

Objective: Build student confidence through tactile engagement.

1. Equipment Distribution (5 mins):
   Split students into groups of 4-5. Distribute Tetrix kits and safety tools (e.g., screwdrivers, pliers, gloves). Assign roles within each group (e.g., parts manager, assembler, tool specialist).

2. Activity (15 mins):

   • Task: Build a simple motorised structure by following pre-designed step-by-step guides provided by the teacher.
   • Focus:
     • Linking beams using screws and nuts.
     • Connecting a motor for basic movement.
   • Groups must agree on roles and communicate effectively to complete the task as quickly and accurately as possible.

3. Midway Check-In (5 mins):

   • Pause students halfway through the activity. Discuss any challenges or wins their group is experiencing. Use this time to reinforce collaboration, critical to robotics projects.

4. Reflection and Wrap-Up (10 minutes)

Objective: Consolidate learning and connect key ideas.

1. Group Presentations (5 mins):

   • Each group presents their completed basic structure to the class.
   • Groups explain which Tetrix components they used and their teamwork approach.

2. Reflection (5 mins):

   • Discussion Prompt: "What part of the task did you find most interesting or challenging today? Why?"
   • Highlight progress and how this foundational knowledge will help them build programmable robots in future lessons.

Differentiation Strategies

To Support:

• Provide a labelled Tetrix parts guide and tool usage sheet for students who may struggle with conceptual understanding.
• Pair less confident students with stronger collaborators.

To Challenge:

• Offer an advanced task, such as identifying how to optimise their build for stability.
• Encourage groups to hypothesise how sensors could enhance their models in future lessons.

Health and Safety

1. Students must wear safety goggles while handling tools.
2. Clear guidance provided on proper use of screwdrivers and other small tools.
3. Ensure all workspaces are clutter-free to avoid accidents.

---

Resources Needed

1. Tetrix Prime kits (one set per group).
2. Safety goggles, screwdrivers, pliers, and gloves.
3. Tetrix parts guide (printed for each student).
4. Pre-built demo robot with a simple working motor.
5. Step-by-step build instructions.

---

Assessment Opportunities

1. Formative Assessment: Observe group participation during the practical assembly task and gauge understanding through Q&A during check-ins.
2. Peer Feedback: Students reflect on and critique their group’s teamwork and results during presentations, encouraging meta-cognition.

Teacher Reflection Post-Lesson

• Were students engaged with the hands-on demonstration?
• Did the reflection discussion reveal student understanding of robotics components?
• What areas are still unclear to students that could inform the next lesson?
