A novel gripper for limp materials based on lateral Coanda ejectors
نویسنده
چکیده
Limp materials like textiles, leather, porous tissues, meat and fish fillets do represent challenges in automation. A universal gripping principle that is usable for all these materials is not known. This paper describes a new gripping principle based on a novel Coanda effect ejector meeting these challenges. This ejector allows the construction of a slim, plate-shaped vacuum gripper with multiple independent suction heads. Each suction head is powered by a newly patented lateral Coanda ejector that ensures gripping power on all soft or porous materials. The paper presents results of investigations on important parameters of the Coanda effect gripper. 2008 CIRP.

An overview of the University of Louisiana robotic gripper system project
This paper summarizes a concluded 5-year funded research project (1994–1999) addressing the automated handling and manipulation of limp material, without distortion, deformation or damage. A series of prototype gripper systems (xed-dimensioned and reconngurable) were developed and integrated with Adept Series manipulators to demonstrate the gripper applicability to the textiles and apparel indu...
متن کاملSuction Control of a Robotic Gripper: A Neuro-Fuzzy Approach
This paper discusses a fuzzy logic control system designed to determine, regulate and maintain the amount of suction needed by a robotic gripper system to perform reliable limp material manipulation. A neuro-fuzzy approach is followed to determine the amount of desired suction (depending on experimentally derived data and plant characteristics). A knowledge-based valve controller is then design...
متن کاملDesign, Fabrication and Intelligent Control of the Gripper Based on SMA Actuators
This paper presents the designing, simulation, fabrication and control of a gripper actuated by Shape Memory Alloy (SMA) wire. The presented gripper has the advantage of the small linear displacement of the slider connected to the SMA wire, and can convert the linear displacement into angular movement of the gripper fingers. In this study, design and simulation processes have been done by two p...

This paper discusses the design and modeling fundamentals of a multi-degree-of-freedom reconfigurable robotic gripper system (RGS), designed to automate the process of limp material handling, reliably and without distortion, deformation, and/or folding. The reconfigurable gripper design draws upon the authors' previously reported flat surfaced, fixed-dimensions gripper system [1]. The design co...
متن کاملValidity of the limp model for porous materials: a criterion based on the Biot theory.
The validity of using the limp model for porous materials is addressed in this paper. The limp model is derived from the poroelastic Biot model assuming that the frame has no bulk stiffness. Being an equivalent fluid model accounting for the motion of the frame, it has fewer limitations than the usual equivalent fluid model assuming a rigid frame. A criterion is proposed to identify the porous ...
