SHS3 Robotics · Semester 1 Week 12: Robot Control Principles

Lesson notes

Learning Objectives

Indicator: 3.1.2.LI.1 - Design a prototype feedback-driven autonomous system for efficiency improvement in an identified local industry.

By the end of the lesson, learners can:

Identify and define a specific efficiency problem in a chosen Ghanaian local industry that could be solved with a feedback-driven autonomous system.
Brainstorm and sketch at least three candidate design ideas for a feedback-based solution, considering the availability of building components.
Select and justify the best design idea based on criteria such as cost, feasibility, safety, and potential efficiency gains.
Construct a working prototype of the chosen design using robotics kits, sensors, actuators, or locally available materials.
Present and defend their team’s design process, explaining how the team arrived at the final solution and how each member contributed.

Exemplars (from the NaCCA curriculum)

Project-Based Learning: Work in small mixed-ability teams to explore, Identify and define a problem in any local industry and follow a Design & Engineering Process to build a prototype feedback-driven solution that addresses the defined problem. The following steps can be followed:
- Brainstorm problems in a typical Ghanaian Local Industry & Ideate feedback-based solutions that address the problem a. Discuss the problems b. Discuss up to five candidate design ideas. c. Consider building components and their availability. d. Prioritise and sketch out three candidate design ideas on paper. e. Choose and justify the best design. f. Build A Prototype of the best design using robotics kits or local materials.
- Discuss the following items with your team and be prepared to share them with the rest of the class. a. How did the team arrive at the final design solution? b. Is the design realistic and well proportioned? c. How did each team member contribute towards the overall design? d. Do you feel like everyone had an equal opportunity to contribute to the creative process?

NB- The Facilitator should provide feedback during each stage of learners' work and request amendments or rework where required.

Assessment (3.1.2.AS.1). The document marks these depth-of-knowledge levels for this indicator: Level 3 Strategic reasoning; Level 4 Extended critical thinking and reasoning.

Teaching and Learning Resources:
- Local materials (e.g., wood, boxes, glue, springs, etc.
- Access to robotics lab with requisite tools (e.g., screwdrivers, glue guns, pliers, multimeters, function generators, etc.), basic sensors and actuators (e.g., light sensors, ultrasonic sensors, temperature sensors, gyro sensors, servo motors, speakers, etc.)
