“…The detective modules for hand posture and task and task monitoring modules are marked in purple, while the tasks marked in green represent the robotic screw arm and automatic screw search modules. We determine the task process in reference to HTA [14][15][16]. The stages are explained as follows.…”

“…The task scheduling of the workflow is generally modeled as a non-extended system in HTA [14] and an extended system in HTA [15], and as a safety-based system in HTA [16]. To further monitor hands, objects, and robot arms in these HTA, it is difficult for the researchers and practicians to propose a control scheme to fully manage kinds of hybrid automation assembly.…”

We develop a monitoring system for humanrobot collaboration (HRC) of hybrid automation. The system enables the production line to avoid product defects as well as guarantee a real-time warning system in a cellular manufacturing (CM). A task semantic monitoring system includes the three-dimensional (3D) hand posture estimation and the motion trajectory monitoring. The coordinate of hand, the motion of hand, and the semantic of hand are identified by two integrated modules. The verification is executed by applying the system to the assembly lines for power protector.

“…3. General operation flow of the cable harness assembly Referring to HTA development guideline by Stanton (Stanton, 2006), the entire cable harness assembly is being decomposed into hierarchical task tree (Tan et al, 2008a). The overall operation objective is set as the main goal followed by general tasks in the assembly plan level as the sub goals.…”

“…(Please refer to table of hazard severity/exposure/avoidance categories, table of risk reduction decision matrix prior to safeguard, table of safeguard selection matrix, and table of safeguard selection validation matrix in ANSI/RIA R15.06) The assessment is done following three fundamental steps, which are identification, measurement and analysis of risk [15]. The initial risk identification (before implementation of safety design) is done from the task modeling of the assembly operation [16], [17]. The identified risk is then being measured by the hazard severity, exposure and avoidance categories to determine the risk reduction category.…”

The key challenge of this work is to research the safety design and development of a close range active human-robot collaboration system in which no governing safety standards and regulations are currently present. Active robot assistance in a human-centered cellular manufacturing system is very promising proposal, however safety is the uppermost consideration before this idea can be materialized. In this development, five main safety designs in both hardware and control levels have been proposed and discussed in this work. In the prototype system development, human area and robot area are setup as safe working areas but border crossing is allowed and monitored for safety. At the close region of collaboration, three safety robot working zones are defined by light curtains to control the behavior of the robot based on the collaboration requirements. The assisting mobile robot manipulators system is designed with additional safety control strategies in term of robot gripper speed and travel area to minimize the collaboration risks. Vision system by IP cameras is developed to monitor the human operator safety conditions by measuring the body posture and position. The overall control system is developed to coordinate the collaboration flow between the human operator and mobile robot manipulators system to ensure the safety of the assembly operation. Risk assessments are conducted to make evaluations before and after implementation of safety design into the prototype system. Various safety improvements are observed and discussed. It has proven that the safety designs can reduce the potential collaboration risks in the system.
