Design team belonging to powertrain divisions can speed up the process of managing information, within gearbox design activities, by adopting digital pattern tools. These tools, belonging to a knowledge-based engineering (KBE) system, can assist engineers in re-using company knowledge in order to improve time-consuming tasks as retrieval and selection of previous architectures and to modify and virtually test a new gearbox design. A critical point in the development of a KBE system is the usability of user’s interface to demonstrate effective reduction of development time and satisfaction in its use. In this paper, the authors face the problem of usability improvement of the graphical user interface (GUI) of the tool belonging to the KBE system and previously proposed. An approach based on analytic hierarchy process and multiple-criteria decision analysis is used. A participatory test is performed for evaluating the usability index of the GUI. Taking into account the data analysis, some changes are carried out and a new GUI release is validated through new experimentations
Enabling technologies that drive Industry 4.0 and smart factories are pushing in new equipment and system development also to prevent human workers from repetitive and non-ergonomic tasks inside manufacturing plants. One of these tasks is the order-picking which consists in collecting parts from the warehouse and distributing them among the workstations and vice-versa. That task can be completely performed by a Mobile Manipulator that is composed by an industrial manipulator assembled on a Mobile Robot. Although the Mobile Manipulators implementation brings advantages to industrial applications, they are still not widely used due to the lack of dedicated standards on control and safety. Furthermore, there are few integrated solutions and no specific or reference point allowing the safe integration of mobile robots and cobots (already owned by company). This work faces the integration of a generic mobile robot and collaborative robot selected from an identified set of both systems. The paper presents a safe and flexible mechatronic interface developed by using MBSE principles, multi-domain modeling, and adopting preliminary assumptions on the hardware and software synchronization level of both involved systems. The interface enables the re-using of owned robot systems differently from their native tasks. Furthermore, it provides an additional and redundant safety level by enabling power and force limiting both during cobot positioning and control system faulting.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
