    Development of Pneumatic Soft Gripper for Effective Material Handling
    (Institute of Electrical and Electronics Engineers Inc., 2024) Naveen, S.; Panigrahi, S.; Vinit, A.; Sudar, I.H.; Thomas, M.J.
    Recent times have shown a drastic transition in robotics from rigid to soft mechanisms. The reason is that soft robots offer safer human-robot interactions, reduce weight and also offer strong environmental adaptability. However, the inherent characteristics of soft materials to exhibit multiple degrees of freedom (DoF) make it challenging to control their movements. Therefore, this paper presents the development of a soft gripper with simple architecture to effectively and economically manipulate delicate objects. The gripper constructed using silicon rubber has an air cavity to actuate its opening and closing pneumatically. This paper presents the different stages of its construction and demonstrates its application on a 4 DoF robotic arm for handling delicate objects. A simulation study of the structural parameters of the proposed soft gripper is also carried out using ANSYS finite element software. The preliminary results show the superior adaptability of the soft gripper in handling objects of various shapes and sizes. The proposed system can find application in food, biomedical and electronic industries. © 2024 IEEE.

    Experimental investigation of rotor wound multi disc magneto-rheological fluid brake
    (SAGE Publications Ltd, 2025) Bhat, S.H.; A, A.; Naveen, S.; Kumar, H.; M, A.
    Magneto-Rheological fluid (MRF), known for changing properties under a magnetic field, is ideal for brakes and dampers in magnetically controlled devices. This research presents a novel design for a 10-disc MR brake using in-house Magneto-Rheological Fluid (MRF), distinguished by its integration of electromagnet windings directly onto the brake shaft. Magneto-static analysis, performed using Finite Element Method Magnetics (FEMM) software, optimized the material selection and dimensions, enhancing the magnetic field distribution across the MRF gap and maximizing braking torque. The design, with rotor windings and a consistent MRF gap, generates a uniform magnetic field, significantly boosting performance. Theoretical braking torque was estimated using Bingham plastic model for MRF characterization, aligning well with experimental results. The compact 10-disc MR brake design, weighing 1.19 kg, shows robust torque performance across varying current levels. Remarkably, prior research had not integrated electromagnet windings directly on the rotor of MR brake, marking this study as pioneering in advancing MR brake performance. © The Author(s) 2025.
