Special Issue Information

Dear Colleagues,

Parallel manipulators have garnered increasing attention in recent decades due to their high stiffness, load-carrying capacity, precision, and dynamic performance. Their closed-loop kinematic structures make them ideal for applications in industrial automation, medical robotics, flight simulators, and high-precision machining. However, the mechanical design of such systems remains a complex and multidisciplinary task, involving challenges in kinematic synthesis, workspace optimization, singularity avoidance, and structural integration. This Special Issue focuses on recent advancements in the mechanical design of parallel manipulators, encompassing innovative architectures, modeling techniques, design optimization, prototyping, and practical applications. We invite high-quality contributions that address both theoretical developments and experimental validations, promoting a deeper understanding of the design principles that underpin high-performance parallel manipulators.

The emergence of surgical robots has revolutionized complex operations, improving precision, lowering operating risks, and shortening recovery periods. Given the merits, an eight degrees of freedom (DOF) hybrid surgical robot (HSR) has been proposed, which leverages the benefits of both serial and parallel manipulators. However, its performance is hindered by the constrained range of motion of its parallel platform. To address the issue, this research presents a systematic approach for designing and optimizing the proposed HSR. The first step is the design of the HSR, followed by a multi-stage design analysis of its parallel platform, concentrating on kinematic, geometrical, and singularity analysis. Higher values of the condition number indicate singular configurations in the platform’s workspace, highlighting the need for an optimized design. For optimization of the platform, performance parameters like global condition number (GCN), actuator forces, and stiffness are identified. Initially, the design is optimized by targeting GCN only through a genetic algorithm (GA). This approach compromised the other parameters and raised the need for simultaneous optimization employing a non-dominated sorting genetic algorithm (NSGA II). It offered a better trade-off between performance parameters. To further assess the working of the optimized parallel platform, workspace analysis and motion planning of a predefined trajectory have been performed. Full article
