Problem statement. Conventional firefighting methods expose personnel to significant risks, particularly in hazardous environments. Robotic systems, specifically manipulators for controlling fire monitors, offer a safer and more efficient alternative by enabling precise delivery of extinguishing agents. However, their effective deployment necessitates a thorough understanding of their kinematic capabilities and limitations. Purpose. This research aims to conduct a comprehensive design and kinematic analysis of a five-degree-of-freedom (5-DOF) articulated robotic manipulator tailored for controlling fire monitors. The study focuses on establishing its foundational kinematic model, evaluating its workspace, and verifying its motion capabilities to lay the groundwork for advanced robotic firefighting systems. Methodology. The research involved the conceptual design of an all-revolute joint manipulator. The kinematic analysis was performed using the matrix transformation method to derive the forward kinematic equations. These equations define the position and orientation of the end-effector (fire monitor nozzle) based on joint variables. Numerical simulations of the gripper’s motion under various predefined joint input scenarios were conducted using Mathematica software to verify the derived equations. Furthermore, the manipulator’s operational workspace and motion were simulated and visualized using SolidWorks CAD/CAE software. Findings (results). The kinematic analysis successfully yielded the transformation matrices and explicit equations for the end-effector’s coordinates. Numerical simulations in Mathematica validated the correctness of these motion equations, demonstrating predictable trajectory generation for different joint inputs. The SolidWorks simulation visually confirmed the manipulator’s kinematic behavior and defined its operational workspace, suitable for targeted fire suppression tasks. The 5- DOF configuration was shown to provide substantial maneuverability for aiming a fire monitor. Originality (novelty). The work provides a detailed kinematic characterization and simulation-based validation of a specific 5-DOF manipulator configuration intended for fire monitor control. While building on established robotic principles, its novelty lies in the focused application and detailed kinematic groundwork for this specific firefighting task, bridging the gap between general manipulator
