| Povzetek: | Mobile manipulators enable robotic systems to operate flexibly in extended, dynamic, and unstructured environments. A key challenge in such systems is achieving coordinated and adaptive behavior between the mobile base and the manipulator without relying on global localization or predefined plans. This paper presents a reactive and fully local control strategy for mobile base based on spatially modulated velocity fields defined in the mobile base’s frame. The method enables real-time end-effector tracking across the full workspace by exploiting only the internal kinematics of the arm. Using distance- and angle-based activation thresholds, the controller generates smooth linear and angular velocity commands for mobile base that support context-aware transitions between stationary, extension, and retreat modes. Importantly, the control framework is decoupled from the manipulator, allowing compatibility with autonomous planning, teleoperation, or physical guidance. The proposed architecture is particularly well suited for dynamic and collaborative manufacturing scenarios, where mobile robots must operate safely, robustly, and without dependence on global pose estimates. Experiments with a real mobile manipulator demonstrate stable and precise behavior across diverse trajectories, confirming the suitability of the method for adaptive, robust, and autonomous robotic systems. |
