“…The other advantages of the digital actuators include their simple structure, low cost, small Joule heat effect, etc. [28,29]. The main drawback is that the manufacturing errors of these actuators have to be precisely controlled, as they cannot be compensated using the control law.…”

Micro conveyance devices are important elements in high precision positioning systems, which play vital roles in many scientific and industrial fields and are widely needed in many applications. This work presents the modeling and experimental validation of a pre-designed and fabricated micro conveyance device. This micro conveyance device consists of eight elementary electromagnetic digital actuators and can realize a conveyance application based on a stick-slip driving principle. A dynamic model based on the prototype device was established for stick-slip displacement simulation. Four sub-models of the dynamic model regarding the calculation of actuation force and friction force within the device were built and integrated. Experiments focusing on the conveyance application were carried out to test the performance of the prototype device. It has been observed that the simulated results obtained using the dynamic model were in good agreement with the experiment results. The proposed device suggests an alternative to the micro conveyance system.

“…The holding function corresponds to the holding of a mobile part at any of the discrete positions to ensure the actuator's repeatability and the digital behavior even in the presence of disturbances. In the literature, several solutions have been employed to realize this function using magnetic holding [35,36], compliant structures [37], and locking actuators [38].…”

In this paper, a novel micro-positioning device based on a 3D digital actuator is presented. The proposed system allows realizing planar motions of micro-objects, which could be implemented in several applications where micro-positioning tasks are needed such as micro-component manufacturing/assembly, biomedicine, scanning microscopy, etc. The device has three degrees of freedom, and it is able to achieve planar motions of a mobile plate in the xy-plane at two different levels along the z-axis. It consists of a hexagonal mobile part composed of a permanent magnet that can reach twelve discrete positions distributed between two z-axis levels (six at each level). Two different approaches are presented to perform positioning tasks of the plate using the digital actuator: the stick-slip and the lift-mode approaches. A comparison between these two approaches is provided on the basis of the plate displacement with respect to different current values and conveyed mass. It was observed that for a current of 2 A, the actuator is able to displace a mass of 1.15 g over a distance of 0.08 mm. The optimal positioning range of the planar device was found to be ±5.40 mm and ±7.05 mm along the x- and y-axis, respectively.

“…The applications can be divided into two groups according to the number of actuators: single actuator and actuators array. Single actuators are typically used for switches for fluidic [8], optical [9], [10] and electrical [11], [12] applications. Digital actuators can also be used as array to perform more complex tasks by combing several elementary actions.…”

This paper presents a conveyance device based on a digital actuators array and a structured plate. The actuators array is composed of four electromagnetic digital actuators, arranged in a 2 × 2 matrix. The principle of the actuators array and of the conveyance device are firstly presented. The control strategy of the array to generate the conveyance task is then described. A prototype of the device is presented and experimentally tested. Conveyance of the structured plate has been experimental realized in different conditions and compared with theoretical results.
