Project actions

01When designing a product that will be used alongside automated systems, consider how to build user confidence in that system.
02Think about how visual cues or feedback from the automated system can reassure the user.

Method & Evidence

AimTo investigate the level of trust human laminators place in collaborative robots during the manufacturing of fibre-reinforced composites and its impact on perceived safety and ease of manufacturing.

MethodHuman trials and questionnaire-based user feedback.

ProcedureHuman volunteers performed composite lay-up tasks in collaboration with two different robotic systems. Their experiences and perceptions of safety, ease of use, and overall manufacturing process were then collected through questionnaires.

ContextManufacturing of fibre-reinforced composites.

Variables

IV["Type of collaborative robotic system (two different approaches)","Collaborative lay-up process"]

DV["Human trust in the robot","Perceived safety","Ease of manufacturing","Ease of use"]

CV["Type of composite material being manufactured","Specific lay-up tasks performed","Volunteer participant pool"]

Strengths & Limitations

Strengths

+Directly addresses a critical human factor in emerging manufacturing technologies.
+Uses a practical application (composite manufacturing) to test human-robot interaction.

Limitations

The study was conducted in a controlled environment, and real-world manufacturing conditions might present different challenges to trust and safety perception.

Reliability & validity

The use of questionnaires provides subjective data, which may be subject to bias. The reliability of trust measures and the validity of the chosen tasks as representative of industrial practice would be key considerations.

Think critically

How might the novelty of the technology or the specific nature of the composite material influence the level of trust observed in this study?

Design Principles

"Human-robot collaboration is most effective when underpinned by demonstrable safety, ease of use, and perceived reliability, fostering user trust and acceptance."

Building trust between humans and robots is crucial for the successful adoption of automation in industries like composite manufacturing. This trust directly impacts worker acceptance, safety perceptions, and ultimately, the efficiency and quality of the production process.

What This Means for Your Design

People feel safer and find it easier to make things when they trust the robot they are working with.

How to use in your project

1.Use this research to justify the importance of user trust and safety in your design process, especially if your design interacts with or is influenced by automated systems.
