“…As the technology advances, ADM development is affected where more compact and miniaturized size ADMs are fabricated. 81 Besides, the recent ADMs are equipped with more sensors and new components such as RFID and camera. As an example, the ADM developed by Ahadani et al 62 as shown in Figure 9(a) does not use many sensors to improve the overall process compared to the one developed by Penna et al 54 in Figure 9(b) that use different types of sensors such as temperature sensor, heartbeat and humidity sensor to improve the overall performance.…”

An automatic system in equipment can be recognized as a systematic control system to minimize human tasks or automatically complete repetitive tasks without human involvement. This review paper focused on the dispensing machines in the medical field particularly the design development of the automated dispensing machines which can be considered as one of the important technologies in pharmacy. This paper also briefly describes the main criteria for fabricating the dispensing machine. Next, different fabrication methods of the dispensing machine such as simple fabrication and 3D printing as well as the materials used in 3D printing are also thoroughly discussed. The last section consisted of the evaluation methods to justify the developed devices by comparing the performance of fabricated products and also through surveys and feedback from patients and medical staff. Based on the performance evaluation of automated dispensing machines as reported in the literature, it can be concluded that the implementation of an automated dispensing machine is necessary for the high-quality guarantee of community healthcare.

“…However, the need for a wide set of tools introduces several challenges, resulting in a more complex, expensive, and time-consuming process. The study and development of innovative flexible tools, able to optimize one or more phases of the assembly process, will overcome the above-mentioned current limits [ 19 ].…”

In the last few decades, industrial sectors such as smart manufacturing and aerospace have rapidly developed, contributing to the increase in production of more complex electronic boards based on SMT (Surface Mount Technology). The assembly phases in manufacturing these electronic products require the availability of technological solutions able to deal with many heterogeneous products and components. The small batch production and pre-production are often executed manually or with semi-automated stations. The commercial automated machines currently available offer high performance, but they are highly rigid. Therefore, a great effort is needed to obtain machines and devices with improved reconfigurability and flexibility for minimizing the set-up time and processing the high heterogeneity of components. These high-level objectives can be achieved acting in different ways. Indeed, a work station can be seen as a set of devices able to interact and cooperate to perform a specific task. Therefore, the reconfigurability of a work station can be achieved through reconfigurable and flexible devices and their hardware and software integration and control For this reason, significant efforts should be focused on the conception and development of innovative devices to cope with the continuous downscaling and increasing variety of the products in this growing field. In this context, this paper presents the design and development of a multi-mode hybrid micro-gripper devoted to manipulate and assemble a wide range of micro- and meso-SMT components with different dimensions and proprieties. It exploits two different handling technologies: the vacuum and friction.

“…Handling, transportation, and manipulation of microparticles or bulk and granular materials can be implemented by various methods and approaches that can generally be divided into two types: prehensile and non-prehensile. Prehensile methods usually involve some sort of force or form closure that is associated with grasping by microgrippers [ 8 , 9 , 10 , 11 , 12 ]. However, prehensile methods are most suited for the manipulation of individual objects, they always involve some mechanical effect on the object to be manipulated.…”

Omnidirectional Manipulation of Microparticles on a Platform Subjected to Circular Motion Applying Dynamic Dry Friction Control

et al. 2022

Currently used planar manipulation methods that utilize oscillating surfaces are usually based on asymmetries of time, kinematic, wave, or power types. This paper proposes a method for omnidirectional manipulation of microparticles on a platform subjected to circular motion, where the motion of the particle is achieved and controlled through the asymmetry created by dynamic friction control. The range of angles at which microparticles can be directed, and the average velocity were considered figures of merit. To determine the intrinsic parameters of the system that define the direction and velocity of the particles, a nondimensional mathematical model of the proposed method was developed, and modeling of the manipulation process was carried out. The modeling has shown that it is possible to direct the particle omnidirectionally at any angle over the full 2π range by changing the phase shift between the function governing the circular motion and the dry friction control function. The shape of the trajectory and the average velocity of the particle depend mainly on the width of the dry friction control function. An experimental investigation of omnidirectional manipulation was carried out by implementing the method of dynamic dry friction control. The experiments verified that the asymmetry created by dynamic dry friction control is technically feasible and can be applied for the omnidirectional manipulation of microparticles. The experimental results were consistent with the modeling results and qualitatively confirmed the influence of the control parameters on the motion characteristics predicted by the modeling. The study enriches the classical theories of particle motion on oscillating rigid plates, and it is relevant for the industries that implement various tasks related to assembling, handling, feeding, transporting, or manipulating microparticles.
