Abstract:

This article proposes a novel, innovative, soft gripper system developed for the manipulation of objects of unknown or unspecified shape and consistence. This could be achieved by the utilization of a linear pneumatic muscle benefitting from an inherently compliant behaviour. A gripper system of this type does not require the presence of sensors or complex controllers, as it is the mechanical system itself that provides the required adaptive behaviour. The compliance of the system is ensured by the variations of the air pressure fed to the pneumatic muscle, monitored and controlled in a closed

Abstract:

This paper discusses the modeling and analysis of a high-speed adjustable grasping robot controlled by a pneumatic actuator. The robot is composed of two grippers, two wires for connecting a pneumatic cylinder and an arm with gripper joints with a spring as well as two stoppers for controlling the gripper stopping point with a brake. By supplying pressurized air into the pneumatic cylinder, the two grippers move forward together with the arm and capture the object by adjusting the air pressure in the cylinder. After capturing the target object, the system can release the object by changing the

Abstract:

Abstract Soft pneumatic actuators, due to their flexibility and ease of deformation, have great application potential in industries such as gripping and handling. The paper presents the design of a parallel dual-channel end-wrapping pneumatic gripper based on a PneuNet-type soft pneumatic actuator. The actuator’s gripping force at the end is enhanced by utilizing two rows of chambers in the dual-channel body, while the wrapping chambers on both sides of the actuator’s end increase the contact area between the actuator and the object being grasped, thereby effectively improving the gripping per

Three prototypes of such grippers are implemented and used to experimentally verify the lifting of objects into an acoustic pressure field.

Abstract:

This paper proposes the design of a wholly mechanical constant-force gripper that can accommodate the imprecise manipulation of brittle/delicate objects by the actuation. This was achieved by designing a constant-force mechanism as the jaw that allowed a constant force to be applied to the grasping objects regardless of the displacement of the mechanism. The constant-force mechanism is attached to the end effector of the gripper via a parallelogram mechanism which ensures that the jaws remain in parallel. The constant-force mechanism combines the negative stiffness of a bistable mechanism and

Abstract Design of new smart prosthetics or robotic grippers gives a major impetus to low-cost manufacturing and rapid prototyping of force-sensing devices. In this paper, we examine piezoresistive force sensors based on carbon nanotube fibers fabricated by a novel wet pulling technique. The developed sensor is characterized by an adjustable force range coupled with high sensitivity to enable the detection of a wide range of forces and displacements limited by the experimental setup only. We have demonstrated the applicability of the developed unit in tactile sensing, displacement sensing, and

Abstract:

Abstract Suction cups has been widely utilized to grasp objects, but they typically encounter challenges with sealing failure and non-adjustable adhesion force. In this study, a bioinspired suction cup integrated with an SMA actuated module was proposed to solve these problems. The actuating performance under different input current was firstly investigated to ensure the effectiveness of the module. Then, inspired by the surface structures of the tree frog’s toe pad, the synthetic bioinspired suction cups with hexagonal microstructures at the rims were designed. The regular cup with soft and s

Abstract:

Abstract Geckos show versatility by rapidly maneuvering on diverse complex terrain because they benefit from the distributed, setae-covered toes and thus the ability to generate reliable and adaptive attachment. Significant attention has been paid to their adhesive microstructures (setae), but the effectivness of the gecko’s adaptive attachment at the level of toes and feet remains unclear. Aiming to better understand geckos’ attachment, we first focused on the deployment of toes by challenging geckos to locomote on varying inclines. When the slope angle was less than than 30°, feet mainly int
