“…The electrodes are placed on the SP following a layout so that their centers' horizontal/vertical Euclidean distance [29] d e is equal to 2·r + d 1 r, where r is the radius of the electrodes. The d 1 is a coefficient to adjust the distance between the centers of electrodes so that the amplitude of the electrostatic forces is enough for moving the microparts, while the undesirable arc phenomenon to be avoided [30]. The value of distance d e is determined so that d 1 ∈ [0.5 0.896].…”

In this paper, an approach is proposed for the simultaneous manipulation of multiple hexagonal and square plastic–glass type microparts that are positioned randomly on a smart platform (SP) using electrostatic forces applied by the suitable activation of circular conductive electrodes. First, the statics analysis of a micropart on the SP is presented in detail and the forces and torques that are applied to and around the center of mass (COM) respectively due to the activation of a SP electrode are determined. The “single electrode activation” (SEA) and the “multiple electrodes activations” (MEA) algorithms are introduced to determine the feasible SP electrodes activations for the microparts manipulation considering their initial configuration. An algorithm for the simultaneous handling of multiple microparts is studied considering the collision avoidance with neighboring microparts. An approach is presented for the simultaneous centralization and alignment of the microparts preparing them for their batch parallel motion on the SP. The developed algorithms are applied to a simulated platform and the results are presented and discussed.

“…It is supposed that the location of the microparts on the platform is known using a vision sensor system. The design of the platform was introduced by authors of this paper in References [ 21 , 22 , 35 ], and a shortcut of the “Smart Platform” is illustrated in Figure 2 .…”

“…The layout of 3 × 3 electrodes (blue circles Figure 3 A) underneath of the rectangular microparts, was designed with respect to the geometry of the platform by Lazarou et al [ 21 , 22 ]. In the present work, regarding to the decrease of the size and the mass of the microparts, an alternative layout of the electrodes of the microparts is proposed in this work; 2 × 2 circular electrodes (blue circles), whose radius r is equal to the radius of the platform electrodes, are placed underneath of the micropart, as it is shown in Figure 3 B.…”

is the distance between the edges of two neighbor electrodes considering the limits for arc avoidance [ 21 ]. Since the micropart moves by the platform electrodes activation (up/down and left/right), then the equilibrium location is that one, where two non-diagonal of the micropart electrodes coincide with the activated ones of the “Smart Platform”.…”

“…A Programmable Platform for the micropart’s motion using electrostatic forces was proposed by Lazarou et al [ 21 , 22 ]. The Programmable Platform consists by an electrodes array embedded on a plastic substrate covered by a dielectric membrane, where microparts with electrodes underneath are manipulated by the activations of the platform electrodes with a constant potential.…”

In this article, a method for microparts parallel manipulation with electrostatic forces, applied by conductive electrodes embedded on a Programmable “Smart Platform”, is introduced. The design of the platform and the layout of the electrodes underneath the rectangular microparts with respect to the platform’s geometry are presented. The electrostatic phenomena that result to the electrostatic forces applied to the microparts by the activated electrodes of the “Smart Platform” are studied in detail. Algorithms for the activation of the platform’s electrodes for the motion of the rectangular microparts are introduced and their motion is simulated. The Configuration-Space (C-Space) of the microparts on the “Smart Platform” is defined taking into account the static obstacles that are placed on the platform and the rest of moving microparts. Considering the layout of the platform, the activation algorithms, the motion and the C-Space of the microparts, a modified A* algorithm is proposed and the best path for every moving rectangular micropart on the “Smart Platform”, is computed with respect to time. Simulated experiments are presented to demonstrate the effectiveness of the proposed approach and the results are discussed.
