“…Bey-Temsamani et al proposed that an intelligent overhead hoist transportation system is to enhance an operator's ergonomics and productivity, with semiautomatic movement, wireless controls, labeling and LED-indicators, and an intelligent gripping system [2]. It is necessary for them to meet multiple strict industrial standards, which include physical load, speed and place control, function specification, effectiveness, and instructions.…”

Research and development on a global scale have been conducted on overhead hoist transportation systems (OHTSs) in recent years. The majority of these systems are utilized in manufacturing facilities that are either semiautomated or fully automated. By using stochastic models to evaluate medication distribution and product delivery processes in automated delivery systems, hospitals can reduce patient waiting times and drug response times. Warehouses are being transformed into fully automated fulfillment factories by using conveyors and shelf-lifting mobile robots, which reduce waiting times and improve efficiency. Modern warehouses are increasingly becoming fully automated fulfillment facilities as a response to the significant development of e-commerce. A significant number of organizations are using mobile robots or conveyor systems to transport shelves. The parts-to-picker model is used to transport stock-keeping units (SKUs) to stationary pickers at picking workstations. The aim of this study is to analyze and organize the relationship between transportation system families. They are utilized in various fields, such as warehouses, hospitals, airports, cross-dockings, etc. Furthermore, this study categorizes a range of synchronization issues that arise from minor variations in workstation configurations within different warehouse settings. Next, we identify a multistation ATS (automatic transportation system) that switches lines to different stations by using overhead conveyors and active line-switching devices. Vietnam’s automated freight problem can be solved with this potential solution. Our study’s findings suggest that enhancing the workstation layout can significantly enhance throughput performance. As a result, the benefits of synchronization can surpass those provided by other well-studied decision tasks.

“…Operators may refuse to use established systems in certain circumstances, which can have negative physical effects and long-term health concerns. This impact is most noticeable for lighter weights because operators find it difficult to resist using assisting systems for larger loads (i.e., greater than 100 kg) [2].…”

“…In the past, several ergonomic interventions have been introduced to reduce the spinal loading in workers. Some examples of interventions include: ergonomic workstation design [21], more frequent and/or longer breaks [22], ergonomic training of workers [23], establishing weight limits [24], as well as using external manipulators to avoid handling weights [25]. In the past years, wearable backsupport exoskeletons have gained remarkable attention given their potential to significantly reduce the loading of lower back anatomical structures.…”

“…Within occupational environments, several measures have been introduced to minimize the incidence of LBP: training workers on correct ergonomic postures [159], adapting workspaces to facilitate ergonomic postures [160], introducing weight limits [24] or using external manipulators such as cranes, to transport weights exceeding the recommended limits [25]. Additionally, in the past years, wearable back-support exoskeletons have been introduced with the goal to relieve the back musculoskeletal system of workers from excessive muscular forces and spinal joint loading [26,27].…”

In high-mix, low-volume manufacturing, end-of-arm tooling (EOAT) must be able to handle various products. Conventional EOATs usually comprise fixed or limited-adjustable frames (i.e. manually or using short-stroke pistons) over-equipped with multiple grippers, which are selectively activated based on the product to be grasped. This paper presents a smart gripper frame equipped with only four grippers capable of automatically adjusting to a product’s unique geometry. To this end, a two-dimensional grasp planner has been developed that is supplied with product contours from depth images. The proposed approach has been successfully validated in multiple industrial use cases involving objects with different dimensions and materials, and applying various grippers.
