“…A vibrating cylindrical stator and two circular plates enable an air bearing based on the NFAL mechanism to position and lift items as discovered in [158]. In 2019, Ran Gabai et al [159], proposed a near-field acoustic levitation-based noncontact stage for item handling and positioning that created an acoustic field with improved pressure able to hold the object without any contact. A very recent study in 2022 by [160] proposed a measurement method of the holding force acting on a levitated object which has a large displacement from the vibration source during near-field acoustic levitation.…”

“…Although levitated spheres can be given angular speed as provided by [172], [173], [174], control over static orientation has yet to be proven. The most common control strategies within literature which had been applied to control the objects manipulation and orientation based on acoustic levitation are PID gain-scheduled controller in [175] and 𝐻 ∞ in [159].…”

Robots play an important role all over the world in the industrial field in terms of dealing with various materials, performing duties quickly and high accuracy as well as in the pharmaceutical/chemical field since robots can handle some issues better than human. Robotic manipulation is the term used to describe how robots deal with many objects. This article reviews the contact and non-contact manipulation with their most common robotic applications and focusing on the non-contact manipulation since it can do specific tasks which contact manipulation cannot do. Reviewing of the robotic non-contact manipulation which include the metal-based robotic manipulation such as magnetic and electrostatic levitation and the non-metal-based robotic manipulation method such as aerodynamic and acoustic levitation have been made in this article. The main core of this article is acoustic levitation which considered one of the most important levitation and manipulation method due to the recent advancements that made it proper to deal with any kind of materials. Here, we review the renowned three methods of acoustic levitation that already using in robotic non-contact manipulation which are standing wave, near-field and single-beam acoustic levitation. Then, we present a performance characteristic of the reviewed methods and the summary of controlling strategies, followed by conclusion and future recommendations for acoustic levitation methods as a non-contact manipulation.

“…It has been reported that TWs can be generated using the Exciter-Absorber method or the Exciter-Exciter method [22]- [24]. The first of these, the Exciter-Absorber mode can be realized when a passive electric network is connected to one of the ceramic piezoelectric patches, glued to the vibrating plate, to absorb the energy.…”

Self-running piezoelectric robots have the advantages of being low cost, high load ratio and fast speed of operation, as well as showing few limitations in confined spaces or for underwater applications. Controlling the speed of motion of such robots by adjusting the Standing Wave Ratio (SWR) along the vibration plate of the robot is important. Compared to the conventional dual-mode excitation method which is based on the adjustment of the excitation frequency, f, a novel SWR-based control method, using the adjustment of the temporal phase shift, θ, has been first derived by the authors. It has been found that the travelling wave component could be maximised using both methods, either by setting the value of f to the root mean square of the two adjacent modal frequencies, or by programming θ to have a sum of π when added to the spatial phase difference. It can be seen that using the 'θbased' traveling wave control method, smoother motion and higher resolution of the motion speed is achieved. In this research, by using the novel θ-based method to drive the robot, its motion characteristics, such as voltagespeed, load capacity and ability to move on different surface materials, have been tested through a series of experiments carried out and reported.
