Life Cycles | Substitute Teacher
Students explore the life cycle of a robotics system from concept to deployment and maintenance. They analyze each stage of the cycle, connect it to real-world robotics projects, and apply the process by evaluating a robot design scenario. This lesson is designed for an adult education classroom with an advanced level of discussion and application.
| Term | Definition |
|---|---|
| Life cycle | The full sequence of stages a robot goes through from idea to retirement. |
| Prototype | An early model built to test a design idea before final production. |
| Iteration | A repeated cycle of improvement based on testing and feedback. |
| Deployment | Putting a robot into real-world use. |
| Maintenance | Ongoing inspection, repair, updates, and replacement of parts to keep a robot working. |
| Retirement | Taking a robot out of service when it is no longer effective, safe, or cost-efficient. |
Briefly introduce the lesson: robotics is not just about building a machine, but managing its full life cycle. State the goal and preview the stages students will analyze.
Listen, ask clarifying questions, and activate prior knowledge about robots they have used or seen.
Present the stages of the robotics life cycle: planning, design, prototyping, testing, deployment, maintenance, iteration, and retirement. Use examples such as warehouse robots, delivery robots, or industrial arms. Emphasize how each stage affects cost, safety, and performance.
Take notes, identify examples, and contribute brief observations or questions.
Display a robotics scenario or case study. Model how to analyze the robot's current stage in the life cycle and what decisions should happen next. Ask targeted questions about risks, user needs, and evidence from testing.
Respond to questions, identify the current stage, and explain what information would be needed to move forward.
Assign students to pairs or small groups. Instruct them to complete the case study task: map the robot’s life cycle stages, identify one problem at each stage, and recommend one improvement or decision for the next stage. Circulate to support and challenge thinking.
Collaborate to analyze the scenario, complete the task, and prepare a brief explanation of their recommendations.
Invite groups to share one key insight or recommendation. Compare approaches across groups and highlight strong reasoning tied to safety, reliability, cost, and user needs.
Present ideas, compare solutions, and note similarities and differences among group responses.
Summarize the lesson by reinforcing that successful robots depend on managing the entire life cycle, not just initial design. Distribute or collect the exit ticket.
Complete the exit ticket, naming one life-cycle stage and one reason iteration matters.
Reinforce that robotics life cycles are iterative and interconnected: planning affects design, testing informs improvement, and maintenance extends useful service. End by asking students to name one stage they think is most critical and why.
Formative assessment will be based on group analysis of the robotics case study and the individual exit ticket. Evidence of learning includes accurate identification of life-cycle stages, logical recommendations, and clear explanation of iteration and maintenance.
