Abstract:
Purpose Varied shapes and sizes of different products with irregular rough surface and fragile properties give a challenge to traditional contact gripping. Single Bernoulli grippers are not suited to handle fragile objects as the impact of center negative pressure force could result in large deformation and stress which damage the materials, and they are also have some limitations for gripping objects with different large and small shapes. Thus, this paper aims to design a non-contact gripper for soft, rough-surfaced and fragile objects gripping with multi Bernoulli heads, which have optimal structures and parameters. Design/methodology/approach The compressed air is ejected into four Bernoulli heads through radial and long flow channels, then passes through four strip-shaped narrow gaps after fully developing in the annular cavity to provide negative pressure. Based on the mathematic model and the computational model, the key structural parameters affecting the gripping performance are selected, and parameters optimization of the gripper is performed by computational fluid dynamics simulation analysis and performance evaluation. The orthogonal method is used and L16 orthogonal array is selected for experimental design and optimization. The characteristics of the designed gripper are tested from the aspects of pressure distribution and lifting force. Findings From the applications in gripping different objects, the designed non-contact gripper can grip varied shapes and sizes of soft, rough-surfaced, fragile and sliced objects with little effect of torque. Originality/value In this paper, a non-contact gripper is designed for handling soft, rough-surfaced and fragile objects based on the Bernoulli principle. A systematic approach, which consists of modeling, simulation, optimization and measurement is provided for the non-contact gripper design and tests.

Abstract:
Il settore agro-alimentare sta diventando un notevole business per le industrie a causa del crescente interesse per il concetto di sicurezza alimentare e della necessità di nutrire il mondo globale. In particolare, il Regno Unito ha investito considerevoli risorse nella ricerca e nello sviluppo per ottimizzare la produttività: questo lavoro di tesi si inserisce in quest’ambito. In particolare le soluzioni meccatroniche analizzate, vertono su due diversi casi di studio: • la progettazione di un’innovativa linea di confezionamento per le fragole; • sviluppo di una piattaforma mobile per il test del suolo. Il primo progetto, in collaborazione con Berry Gardens, azienda leader nel Regno Unito nel commercio della frutta rossa, consiste nel ri-progettare una linea di confezionamento fragole. Partendo da un attuatore di Bernoulli, lo studio preliminare si è concentrato sulla progettazione di una nuova generazione di manipolatori in grado di minimizzare i danni sul prodotto, con annessi relativi test per valutare le sue potenzialità. Inoltre, è stata sviluppata una stazione di trattamento UV in grado di trattare fragole su entrambe le superfici per massimizzare l’effetto di decontaminazione. Infine è stata presentata la soluzione finale della linea di confezionamento. Il secondo progetto, in collaborazione con l'università norvegese University of Life Sciences, ha come obiettivo quello di assemblare una piattaforma composta dal robot mobile Thorvald II sviluppato dall'Università norvegese, e un robot cartesiano, prodotto dalla società SMC, al fine di costituire una piattaforma mobile autonoma per l’analisi del suolo. Entrambi i progetti sono stati sviluppati presso l'Università di Lincoln, Regno Unito, con la collaborazione di School of Engineering, School of Computer Science, Lincoln Institute for Agri-Food Technology (LIAT) e di partner industriali dell'Università.

Abstract:
Abstract An increasing range of engineering applications require soft grippers, which use compliant mechanisms instead of stiff components to achieve grasping action, have high conformability and exert gentle contact with target objects compared to traditional grippers. In this study, a three-fingered gripper is first designed based on a notched self-folding mechanism actuated using an electrostrictive PVDF-based terpolymer. Then the design optimization problem is formulated, where the design objectives are to maximize the free deflection Δfree and the blocked force Fb. A computationally efficient two-stage design optimization procedure is proposed and successfully applied in the gripper design. NSGA-II is adopted as the optimization algorithm for its capacity to deal with multi-objective optimization problems and to find the global optima with high design variables and large design domains. In stage one, computationally less expensive analytical models are developed based on Bernoulli-Euler beam theory and Castigliano’s theorem to calculate Δfree and Fb. Utility function is applied to determine the best design in the last generation of stage one. In stage two, 3D FEA models are developed, using the dimensions determined by the best design from stage one, to investigate effect of the shape of segment surfaces on the design objectives. Overall, the proposed two-stage optimization procedure is successfully applied in the actuator design and shows the potential to solve a wide range of structural optimization problems.

Abstract:
This paper presents the modeling and prediction of the air flow, pressure and holding force produced by a non-contact Bernoulli gripper, which is essentially a radial air flow nozzle, used to handle small and large, rigid and non-rigid materials. Previous studies have demonstrated the turbulent behavior of the flow and the presence of a flow separation region at the nozzle of the gripper. Here, a Reynolds stress model has been implemented in a finite volume based segregated Reynolds-Averaged Navier-Stokes solver. Compressible air is modeled to capture the effect of the high flow velocities generated by the nozzle. In addition an experimental set up is designed to validate the model. Experimental results of air pressure and force agree favorably with those predicted by the model. This model could be used to understand the influence of handling variables such as the stand-off distance and air flow rate on the suction pressure distribution and lifting force acting on the handled object.

Abstract:
Abstract Once it is designed, the stiffness of a compliant mechanism is not intended to be changed in order to adapt to special operation conditions. Nevertheless, various operation tasks e.g. mechanical grippers, would benefit from such a feature. The effect of axial compression forces, however, is well known to reduce the transverse stiffness of beam-like structures. This paper deals with the effect of prestressing forces on compliant mechanisms. For this purpose, a mathematical description for a modal analysis of compliant mechanisms — based on the author’s former publications — is presented first. Building on this and using a compliant mechanism with one desired translational motion as example, the effect of prestressing forces on the desired deformation and its related stiffness value is analyzed using conventional methods which are based on the Bernoulli-Euler beam equation. However, these methods do not usually consider the undesirable deformations of a mechanism. The modal analysis mentioned above is therefore used in order to examine the effect of prestressing forces on both the desired and undesired deformations. In this analysis, two different compliant mechanisms in several load cases are examined.
