This paper provides a comprehensive review of the development of Collaborative Mobile Industrial Manipulator (CMIM), which is currently in high demand. Such a review is necessary to have an overall understanding about CMIM advanced technology. This is the first review to combine the system architecture and application which is necessary in order to gain a full understanding of the system. The classical framework of CMIM is firstly discussed, including hardware and software. Subsystems that are typically involved in hardware such as mobile platform, manipulator, end-effector and sensors are presented. With regards to software, planner, controller, perception, interaction and so on are also described. Following this, the common applications (logistics, manufacturing and assembly) in industry are surveyed. Finally, the trends are predicted and issues are indicated as references for CMIM researchers. Specifically, more research is needed in the areas of interaction, fully autonomous control, coordination and standards. Besides, experiments in real environment would be performed more and novel collaborative robotic systems would be proposed in future. Additionally, some advanced technology in other areas would also be applied into the system. In all, the system would become more intelligent, collaborative and autonomous.
Superplastic forming of titanium is typically restricted to low volume, high value products due to the high costs inherent in the current process. Problems contributing to the high costs stem from the interactions that take place at the die/part interface and include; poor part surface finish due to the build-up of corrosion products on the die surface and part distortion due to adhesion at the die surface. This paper describes novel methods for the investigation of the build-up of corrosion products on the die using surface digitization tools with laboratory based simulations of the forming conditions and a novel method for monitoring, analyzing and quantifying the die surface condition in a production environment using a combination of thermal imaging techniques and image analysis.
Nous décrivons un nouveau projet européen appelé impératrice, financé par le Programme européen d'innovation et de recherché en métrologie (EMPIR). Ce projet commencera pendent l'été 2015, et durera triois années. Il permettra d'améliorer de manière significative l'efficacité des processus de fabrication de haute valeur en améliorant la capacité de mesure de température. Le consortium du projet compte 18 partenaires, de la communauté de la métrologie (NMI et DI), l'industrie manufacturière de haute valeur, fabricants de capteurs de température, et le milieu universitaire. Le contrôle précis de la température garantit l'efficacité des processus et la qualité du produit. L'amélioration de l'efficacité des processus peut prendre plusieurs formes, notamment: la réduction du rejet de produits / déchets; une meilleure efficacité énergétique; l'augmentation des intervalles entre les vérifications de capteur / entretien; et la fiabilité accrue du capteur, ce qui minimise la fréquence d'intervention de l'opérateur. La traçabilité des mesures de température à l'échelle internationale de température de 1990 (ITS-90) est un facteur critique pour l'incertitude de mesure et la reproductibilité ainsi que pour la qualité et l'efficacité du contrôle de processus permettre cette traçabilité in situ (c'est-à-dire dans le processus industriel) est un thème récurrent dans ce projet.
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.
