In many of these applications, inherent structural flexibilities are unavoidable and lead to vibrations. Consequently, these residual vibrations detrimentally affect working efficiency and positioning accuracy. The present work introduces a novel approach by formulating a nonlinear dynamical model of a spatial multi-link manipulator mounted on a mobile platform. This model incorporates both rigid and flexible links, as well as the payload, enabling a comprehensive study of end-point residual vibration characteristics. The dynamic modeling employed in this study accounts for the interplay of coupled geometric and inertial nonlinearities arising from motion interactions among joints, actuators, and elastic link deflections. The manipulator configuration comprises rigid components and two 3D-flexible links actuated by prismatic and revolute joints, respectively. The flexible links are modelled using Euler–Bernoulli beam elements, while time-dependent in-plane motion is imparted to the rigid link. Utilizing Hamilton’s variational principle, a set of nonlinear governing equations of motion is analytically derived. Subsequently, an independent generalized coordinates system is adopted to transform the equations of motion into a nonlinear reduced form. This is achieved through discretization of the spatio-temporal equations, facilitating the analysis of trajectory dynamics for the robotic manipulator. The residual vibration characteristics at the payload end were explored graphically by applying generalized sinusoidal and bang-bang torque profiles to their respective joints. Nonlinear structural flexibility and material properties emerge as pivotal factors influencing these residual end-point vibrations. It has been observed that the bang-bang torque profile extends the settling period in residual vibration due to its intricate transition characteristics, in contrast to the sinusoidal motion profile with a specific torque duty cycle. Numerical simulations highlight that variations in physical and geometric variables significantly impact end-point residual vibrations and joint deflections, potentially leading to positioning errors in the control of spatial flexible manipulators.</p>","PeriodicalId":44563,"journal":{"name":"International Journal of Intelligent Robotics and Applications","volume":"20 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2024-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141197583","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For handling different types of objects hard as well as soft, require different types of the gripper. The employment of compliant soft-robotic grasping systems, which are characterized by high flexibility in terms of workpiece shape, dimension, and anatomy, is a good method to incorporate greater flexibility into production. The study's major goal is to build and analyses the soft-robotic grippers in terms of repeatability with large payload capacities. End effector (soft gripper) control is crucial for precision work by applying different gripping forces according to the object going to pick. The selection of suitable gripping force for a particular object is done by the process of machine learning (ML). The soft gripper is designed, fabricated, and tested using Industrial Robot (IRB 360) flex picker robot. The virtual environment is created to move the linear path using Robot studio software with rapid programming language. The accuracy, precision, recall, and receiver operating characteristic curve (ROC) curve are analyzed and predict the gripper force accurately with 94% when compared with experimental value. The gripper is working effectively from 1.4 to 2.8 bars with a maximum payload of 500 g. The soft flexible gripper angle is measured based on the pressure using an image processing edge detection technique. The optimized best possible gripping force is predicted using different objects and control action is done to supply exact force to the gripper.</p>","PeriodicalId":44563,"journal":{"name":"International Journal of Intelligent Robotics and Applications","volume":"42 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2024-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140930932","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We propose an MR-based navigation framework for robot-assisted endovascular procedures. The framework allows the acquisition of real-time MR images; segmentation of the vasculature and tracking of vascular instruments; and generation of MR-based guidance, both visual and haptic. The instrument tracking accuracy—a key aspect of the navigation framework—was assessed via 4 dedicated experiments with different acquisition settings, framerate, and time.
