“…Taking φ = 0 as the reference point, setting φ = π/25 = 0.02 × 2π requires moving the mirror along Oy by 0.02 λ L = 15.4 nm. This is within the range of the current technology which allows precise and stable nanometer positioning [35,36]. Fixing γ = 0.98 requires fixing the ratio of the Rabi frequencies with a precision better than 2%.…”

Through a combination of laser beams, we engineer a 2D optical lattice of Mexican hat potentials able to host atoms in its ring-shaped wells. When tunneling can be ignored (at high laser intensities), we show that a well-defined qubit can be associated with the states of the atoms trapped in each of the rings. Each of these two-level systems can be manipulated by a suitable configuration of Raman laser beams imprinting a synthetic flux onto each Mexican hat cell of the lattice. Overall, we believe that the system has the potential to form a scalable architecture for atomtronic flux qubits.

This article presents a miniature tubular moving magnet linear oscillating actuator (MT-MMLOA) that operates on an electro dynamic actuation mechanism. The proposed linear oscillating actuator comprises two main parts: the stator and the mover. In this topology, the stator assembly is composed of a modular C-core structure along with a separator to prevent flux cancelation, and the mover assembly accommodates axially magnetised permanent magnets (PMs) that contribute to high thrust force generation and present a less costly actuator compared to the conventional actuator design. The finite element analysis is performed and validated experimentally. Numerous linear oscillating actuator topologies proposed previously in the literature are compared with MT-MMLOA to analyse the electromagnetic performance. The results show that the motor constant, which is the performance parameter, is significantly increased from the conventional design. The PM volume is reduced, which is cost-effective. The overall volume of MT-MMLOA is also reduced due to reduction in the PM volume, which is advantageous for compactness. Consequently, the proposed MT-MMLOA is simple in structure, less costly, and easy to fabricate.

“…Together with other benefits inherited by the parallel kinematic configuration such as closed-loop structure architecture, high non-actuating stiffness, and less sensitive to external disturbances etc., the compliant parallel mechanism (CPM) is widely preferred over its serial counterpart [1]. For the past two decades, CPM has become a potential solution for various applications such as nanopositioning actuators [2,3], precision manipulators [4][5][6][7][8][9][10][11][12][13][14][15] and MEMS devices [16][17][18]. In particular, numerous manipulators with different degrees-of-freedom (DOF), e.g., 1-DOF [4], 2-DOF linear-motion [5][6][7], 3-DOF planar-motion [8][9][10], 3-DOF spatial-motion [11][12][13] and 6-DOF [14,15], have been developed for a variety of industrial applications such as micro/nano fabrication/assembly systems, manipulation of cells, micro surgery and optical alignment devices, etc.…”

This paper presents a novel three degrees-of-freedom (DOF) compliant parallel mechanism (CPM) with a fully decoupled spatial motion (θX−θY−Z) and optimized mechanical properties. To design the CPM using the beam-based structural optimization method, several novel criteria for synthesizing three-legged CPMs with fully decoupled motions are derived. The obtained results suggest that the synthesized CPM delivers a diagonal compliance matrix, a large workspace of 10deg×10deg×7mm, fast dynamic response of ∼100Hz, and good stiffness performance whereby the translational and rotational stiffness ratios are ∼3600 and ∼570, respectively. A prototype of the synthesized CPM is fabricated using one of the three-dimensional (3D) printing technologies, electron beam melting (EBM). Experimental results have shown that the 3D printed CPM can produce the full workspace with deterministic mechanical properties whereby the highest deviations between the theoretical and experimental results are 11.2% and 1% for stiffness and dynamic behaviors, respectively. Importantly, the decoupled-motion characteristic is also verified via an energy approach, i.e., the energies of the undesired parasitic motions are minor (<1%) as compared with the energy of the desired motion. In addition, several comparisons are conducted to clarify the advantages of the synthesized CPM to the existing designs. All these investigations suggest that the proposed CPM can be used in precision positioning systems due to the good stiffness characteristics, large workspace, fast dynamic response, and decoupled output motions.
