    Design and Analysis of a Hydraulic Scissor Lift Trolley.
    (Kabale University, 2024) Katwesigye, Wilfred
    This project focused on designing and analyzing a hydraulic scissor trolley to address the safety hazards and inefficiencies associated with manually handling heavy food sacks in warehouses and food stores. Current practices often involve workers climbing trailers using makeshift wooden stairs without guardrails, creating serious risks of falls and injuries. To improve safety and efficiency, the hydraulic scissor trolley offers a secure and ergonomic solution that minimizes injury risks while boosting worker productivity and operational flow. Powered by hydraulic fluid that drives a cylinder, the scissor lift allows for vertical movement of the platform. This project provides a comprehensive overview of essential components, such as hydraulic cylinders, scissor arms, and the base structure. Materials were selected for optimal durability and strength to withstand operational demands. Engineering sketches detail component dimensions, supported by static stress analysis performed using advanced software like Ansys and SolidWorks. The analysis includes calculations for lift height and additional lifting range, illustrating how this innovative design enhances safety and optimizes material handling in food storage facilities. By implementing this solution, the project aims to reduce delays and bottlenecks, thereby increasing overall productivity in warehouse operations.

    Design and Analysis of a Serial Manipulator for Pick and Drop Objects for Material Handling at Uiri Metal Forming Workshop.
    (Kabale University, 2024) Behangana, Abert
    This dissertation focused on the design and analysis of a 3-degree-of-freedom (3-DOF) serial manipulator tailored for handling hot objects at the UIRI metal forming workshop. The design process prioritized critical customer requirements, including maintainability, safety, usability, and adaptability. Five design alternatives human hand, jib crane, mobile crane, industrial serial manipulator, and belt conveyor were conceptualized and evaluated using a Pugh matrix against criteria such as load capacity, precision, and cost-effectiveness. Static and dynamic analyses conducted via ANSYS Workbench validated the manipulator's structural integrity under a 50N load, confirming its resistance to significant deformation during operation. MATLAB's ode45 and Simulink were employed to simulate joint motion and trajectory planning, providing insights into the manipulator's dynamic behavior under varied scenarios. Material selection was integral to the study, with A-36 steel, 6061 aluminum alloy, and 304 stainless steel analyzed for properties like deflection and stress resistance. A-36 steel emerged as the optimal choice due to its superior weight-to-structural stiffness ratio, while 6061 aluminum proved advantageous for weight-sensitive applications. Motion planning employed the Jacobian matrix to identify potential singularities and discrepancies between desired and actual trajectories. This analysis enhanced the understanding of motion control and trajectory optimization. Future recommendations include refining control algorithms, integrating advanced safety features, and exploring innovative materials to improve performance. Training programs for operators will also be developed to enhance usability and ensure safe operation. By addressing these aspects, the manipulator design advances precision, reliability, and operational efficiency, contributing significantly to industrial applications requiring high-performance automation solutions.
