“…Every task is specified through the concrete, actual goal that it accomplishes. A tree structure 34 or the more space‐efficient format of a table 36 presents the two‐fold relationship of hierarchy and, often (but this is not the general rule), of the sequence of the tasks.…”

Collaborative robots are an emerging technology falling within the scope of Industry 4.0 and based on the concept of Human-Robot Collaboration (HRC). Unlike traditional industrial robots, collaborative robots are used in shared workspaces with no safety fences. Hence, prospective hazardous contacts need to be avoided or mitigated through a risk assessment. The normative standards such as ISO TS 15066 suggest a list of common hazards, but do not guide the robot system user through the risk assessment process. To address this shortcoming, this paper proposes a practical eight steps risk assessment approach, resulting in a risk priority list. In order to provide an accurate, practical, quantitative and supportive tool for HRC environments, the Failure Mode and Effects Analysis (FMEA) and the Proportional Risk Assessment technique (PRAT) techniques are proposed for risk assessment. The two techniques mentioned above are combined in the suggested new methodology, highlighting both their benefits and disadvantages. The proposed methodology is applied with positive results to a collaborative brick-lifter case study.

“…The term collaborative task is introduced for clarity in discussing interaction and safety. Methods such as Hierarchical Task Analysis (HTA) have been used to analyze assembly tasks in the context of a collaborative system [108]. Table 5.2 illustrates sequence of subtasks delegated to an operator and a robot for the demonstrators discussed in chapter 4.…”

“…Tan et. al [7] describe an engineering approach of the redesign of a manual process to a collaborative process with protective guards and only small overlapping working areas of human and robot. The redesign uses hierarchical task analysis to analyze the structure of the process and a combination of collaboration analysis and analytic hierarchy process to distribute the workload between human and robot.…”

The integration of lightweight robots and service robots into industrial work places forms the new area of industrial service robots characterized by the transformation of manual processes to human robot interactive processes. Still, it is highly difficult to decide which manual processes are qualified for automation or collaboration. Consequently, only few collaborative processes can be found in industry. The objective of the project MANUSERV is to support decisions towards this transfer by developing a tool that supports users to identify practical technical solutions. The tool is a combination of a planning system and a simulation system. The aim of the planning system is to select technically feasible solutions and generate task sequences that solve the problem. The simulation system verifies the proposed solution and evaluates it technically, economically, and ergonomically. Manufacturers of service robots can provide their service robot specifications to be included into the system selection process.
