“…The EAST (Event Analysis of Systemic Teamwork) methodology (see Walker et al, 2005 in this issue for a more in-depth discussion of the approach) takes data from Hierarchical Task Analysis (Annett, 2005-Annett et al (2000 have demonstrated how HTA can be used to capture the principle components of team work in an AntiSubmarine Warfare task), direct observation of tasks, and debriefing interviews using the Critical Decision Method (Klein & Armstrong, 2005) to produce three main representations of a system: a social network, a task network and a knowledge network. We believe that these networks offer different, but compatible, facets of systems representation.…”

The purpose of this paper is to propose foundations for a theory of situation awareness based on the analysis of interactions between agents (i.e., both human and nonhuman) in subsystems. This approach may help promote a better understanding of technology-mediated interaction in systems, as well as helping in the formulation of hypotheses and predictions concerning distributed situation awareness. It is proposed that agents within a system each hold their own situation awareness which may be very different from (although compatible with) other agents. It is argued that we should not always hope for, or indeed want, sharing of this awareness, as different system agents have different purposes. This view marks situation awareness as a 1

“…It is similar to traditional task analysis techniques (Annett, 2003;Crandall & Klein, 2006;Endsley et al, 2003;Schraagen et al, 2009), but we extend these types of analysis tools to support designing for interdependence by:…”

“…These types of interdependence are relevant for human-machine design but are insufficient to cover the nuances of close collaboration of human and machine working jointly on a task. Other research communities have developed Hierarchical Task Analysis (HTA) (Annett, 2003) as a method for identifying and decomposing complex tasks. Cognitive Task Analysis (CTA) (Crandall & Klein, 2006;Schraagen, Chipman, & Shalin, 2009) has extended this methodology to include a representation of the knowledge and reasoning required to perform tasks.…”

Coactive Design is a new approach to address the increasingly sophisticated roles that people and robots play as the use of robots expands into new, complex domains. The approach is motivated by the desire for robots to perform less like teleoperated tools or independent automatons and more like interdependent teammates. In this article, we describe what it means to be interdependent, why this is important, and the design implications that follow from this perspective. We argue for a human-robot system model that supports interdependence through careful attention to requirements for observability, predictability, and directability. We present a Coactive Design method and show how it can be a useful approach for developers trying to understand how to translate high-level teamwork concepts into reusable control algorithms, interface elements, and behaviors that enable robots to fulfill their envisioned role as teammates. As an example of the coactive design approach, we present our results from the DARPA Virtual Robotics Challenge, a competition designed to spur development of advanced robots that can assist humans in recovering from natural and man-made disasters. Twenty-six teams from eight countries competed in three different tasks providing an excellent evaluation of the relative effectiveness of different approaches to human-machine system design.

“…HTA has numerous applications in different areas, such as entertainment, police and military, space exploration, manufacturing, and mining and agriculture [23]. In order to constitute the HTA diagram, all tasks should be defined as goals and sub-goals; they all must be completed to achieve the final goal [24]. In this specific study of human-robot collaboration, HTA [25][26][27] would be a very effective method to determine the collaborative tasks between humans and robots.…”

Safety Design and Development of a Human-Robot Collaboration Assembly Process in the Automotive Industry

Human-robot collaboration (HRC) is a complex procedure in manufacturing due to the problems posed by compatibility and operational safety among humans and robots, and by task definitions among them in a collaborative order. In this paper, the research results of the human-robot collaboration study for the case of an automotive brake disc assembly is presented. The analytic hierarchy process (AHP) is proposed as a decision-making method for the human-robot collaboration system, and detailed hierarchical task analysis (HTA) is applied to allocate operational tasks to humans and robots, thus reducing the chance of duty interference. Additionally, a virtual environment software (Tecnomatix Process Simulate, version 11.1,80, Siemens, Munich, BY, Germany, 2012) is used to model the assembly workstation, providing an opportunity to evaluate the feasibility of the process through different scenarios. Finally, an experimental test is conducted to evaluate the performance of the assembly procedure. This research proves that, although human-robot collaboration increases the total process time slightly, this collaboration improves human ergonomics considerably and reduces the operator injury risk.
