چکیده
Abstract Four-dimensional (4D) printing is an emerging additive manufacturing (AM) technology that adds a time-dependent reconfiguration dimension to three-dimensional (3D) printed products. It enables the creation of on-demand, dynamically controllable shapes, or properties in response external stimuli such as temperature, magnetic field, and light. Thermally responsive structures are among most popular types currently available 4D-printed due their convenience. However, applications like soft robots hindered by temperature-sensitive structures' stagnating actuation. This research was driven requirement for rapid effective design optimisation strategy bi-stable thermally use robotics. In this study, surface method (RSM) optimization with aid numerical solutions used investigate parameters bi-stable, robotic gripper. approach proposed accelerate actuation shape-morphing can be controlled situ strains post-manufacturing heat variable parameters. By using RSM solution individual effects well coupling on output responses, including maximum strain energy average distance between clamps structure, evaluated. The obtained results employed develop designation improve acceleration grippers fast buckling bending, which desirable applications. Graphical abstract

متن کاملDesign fundamentals of a reconfigurable robotic gripper system
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 کاملA dexterous robotic gripper for autonomous grasping
In advanced robotics applications in unstructured environments (e.g. those foreseen in space) some degree of dexterity and autonomy is necessary in order to safely and successfully execute the required tasks. With this respect, besides the kinematic configuration, important aspects to be considered in the design of robotic end effectors are the sensorial equipment and proper control strategies....
متن کاملDesign and Performance of a Multi-Port Robotic Suction Gripper
This paper presents the mechanical-workings and gripping performance characteristics of a vacuum-based robotic gripper. The gripper uses multiple ports with attached commercial suction cups to grasp objects from a variety of directions using suction power. The valves remain closed until opened by a hinge-based mechanism, in order to eliminate vacuum leakage. The ability for the valves to be act...
متن کاملDesign of a Variable Stiffness Soft Dexterous Gripper
This article presents the design of a variable stiffness, soft, three-fingered dexterous gripper. The gripper uses two designs of McKibben muscles. Extensor muscles that increase in length when pressurized are used to form the fingers of the gripper. Contractor muscles that decrease in length when pressurized are then used to apply forces to the fingers through tendons, which cause flexion and ...
