I am a final-year Mechanical Engineering student with a strong interest in computer-aided design (CAD) and mechanical system development. My studies have helped me build solid skills in 3D modelling, simulation, and design optimization using software such as SolidWorks and MATLAB. For my final year project, I am focusing on CAD design to develop innovative and efficient mechanical solutions. I am passionate about applying engineering principles to real-world challenges and aim to pursue a career in mechanical design and product development, contributing to practical and sustainable engineering innovations.

Title: Development and Manufacturing of Autonomous Lawn Mowing Robots My final year project focuses on the CAD design and structural analysis of an autonomous robotic lawn mower. The aim is to develop a durable, efficient, and cost-effective exterior structure suitable for residential and light commercial applications. Using the MoeBot S20 as a reference model, I employed SolidWorks to design and simulate key external components including the main chassis, casing cover, wheel assemblies, and cutting mechanism. Material selection and design optimization were central to this project. Components were assigned materials such as ABS plastic, polyurethane, Nylon 101, stainless steel, and PEEK to balance strength, weight, and manufacturability. Static stress, modal, and drop-test simulations were conducted to assess performance under realistic operational loads, vibration, and impact conditions. Results confirmed that the proposed design maintains high structural integrity, low stress levels, and minimal deformation, indicating excellent reliability and service life. Beyond achieving a robust structure, the project emphasizes Design for Manufacture (DFM) and Design for Disassembly (DFD) principles. These approaches reduce part complexity, enhance ease of maintenance, and improve long-term cost-efficiency. Features such as a detachable casing cover, self-locking rib connections, and a top-mounted cutting-blade fastening system simplify servicing and assembly. The project demonstrates how advanced CAD modelling and simulation tools can guide the creation of high-performance mechanical systems prior to physical prototyping. The results highlight that through thoughtful material selection and integrated design validation, autonomous mowing systems can be made more reliable, sustainable, and user-friendly. Future development will involve prototype fabrication and the integration of energy-efficient power systems and AI-based navigation, expanding the mower’s capability and practical applicability.
