PRESCRIBED LEARNING OUTCOMES

It is expected that students will:

use sensing devices for feedback in a system or subsystem
design and construct products that integrate electronic, electrical, pneumatic, hydraulic, and mechanical systems and subsystems, and that meet industry standards
develop and apply codes for controlling robotics systems

SUGGESTED INSTRUCTIONAL STRATEGIES

Students learn how, in industry, simple devices are integrated to make complex systems. As students design, create, and use simple devices, they gain an understanding of more complex systems and their applications.

Work with students to identify specific tasks they would like a robot to execute (e.g., tracing a path, stacking blocks, picking and placing). Then have them use a computer control program to make a robot perform the tasks.
To build on students´ understanding of how codes are developed to control a system, ask them to print graphic representations of products of their choice (e.g., gearshift, paperweight) and produce printouts of the tool paths. Then have them use machine codes, or import CADD programs to a CNC machine, to construct the products.
Discuss with students how electric, electronic, pneumatic, hydraulic, and mechanical systems are integrated to design and construct a functional product. Challenge teams of students to each integrate two or more of the systems to create a product such as:
- a door opener
- a residential security system
- a vehicle security system
- recreation or exercise equipment
Inform students that they should include schematic drawings, written descriptions, models, and safety standards required to manufacture the products.

Have students develop owner´s manuals to explain the safe operation of products they have created. As they work, encourage them to review various manuals to identify document features they would like to apply.

SUGGESTED ASSESSMENT STRATEGIES

As students resolve complex design problems, they can demonstrate their understanding of how simple devices work together in complex integrated systems.

As students develop and apply command codes to control a robotics system, observe the extent to which they are able to:
- create clear graphic representations or tool paths for the finished product or task
- develop or select the command codes that result in a successful finished product or task
Collect student projects (and accompanying portfolios) that demonstrate the integration of a number of systems (e.g., door opener, car alarm) and look for evidence that students are able to:
- use schematic drawings
- use correct and appropriate construction tools
- effectively integrate systems
- include safety considerations in their designs
Help students analyse a device that uses sensors for feedback in a system by asking them the following questions:
- What other sensing devices could have been used?
- Would another sensor have been more efficient?
- Is there a range of sensitivity that is easily adjusted?
- Is the device safe for the operator?
Before students develop owner´s manuals for their products, have them examine commercially available manuals to develop a list of criteria for assessing their own documents. When students have completed drafts of their manuals, ask other students to provide feedback by completing sentence stems such as the following:
- One thing that was very clear and easy to understand was ____________.
- One thing that was not clear was ____________.
- A change I would make to the organization of the manual is ____________.
- Another way you could highlight the safety precautions is ____________.
