Повний текст джерелаLogistics involves the storage and displacement of goods. These goods are stored in warehouses and shipped to retailers in pallets. Pallets are produced on a customer’s order. Order picking for a pallet is a fatigue induced process resulting in poor performance of the workers, decreasing the productivity and inducing delays in supply chain. Flexibility is introduced to increase productivity by commissioning robots for process automation. These robots consist of autonomous ground vehicles for transporting freight and static manipulators for pick and place. A static robot has limited workspace and the capability of a manipulator is significantly enhanced by adding a mobile base. Mobile manipulation is now being exploited for pick & place and pallet production. This thesis presents a first attempt to achieve autonomous palletization using mobile manipulation. To acquire palletization by mobile manipulation requires the identification of functional blocks, to conceive a framework to achieve this task. A thorough state of the art has been prepared in this thesis corresponding to each element of the global framework. To realize the proof of concept, a prototype has been developed by leveraging existing technologies, by integrating a mobile base with manipulator and a grasping system with a gripping element. For each functional block of the global framework, control execution strategies have been developed and tested in industrial environment. Specifically, localization is acquired by the use of synthetic landmarks, a motion planning and control strategy is employed for global navigation and a rack tracking motion control has been developed for moving inside the racks. To combine and execute all the elements without deadlocks a coordination framework is used as a global supervisor. The path planner for global navigation is based on the shortest distance between two points, and rack tracking is developed by applying the conventional Hough transform to the lidar data and using the output in a nonlinear controller, while the motion planner for manipulation is based on linear trajectories. The framework for supervisory control is based on discrete event systems topology and state machines corresponding to each element have been modelized using Petri nets. Finally, the framework has been tested for a complete picking task on the mobile manipulator to validate the selection of strategies and performance of each functional element. The successful demonstration has been concluded as a first step towards the evolution of autonomous palletization

Повний текст джерелаIn logistics warehouses, automation in the sense of robotization is frequently being employed to cut down production times by efficiently managing the processes of picking heavy loads, place, pack and palletize, while reducing the risks and errors to improve the working conditions of human operators along the way. The flexibility of human is fundamental for order preparation owing to adaptive skills for task variation, but at the same time increasing productivity is complemented with fatigue (musculoskeletal disorders). In this context the research presented in this thesis is a contribution in the robotization of palletization operations requiring exceptional versatility of manipulation and gripping. We have proposed an innovative solution of utilizing a humanoid torso equipped with two manipulator arms with adaptive grippers to grasp and hold the objects of variable size and mass. The main contribution of research is the development of a hybrid Force / Position-Position control law with commutation and estimation of the object surface slip, while taking into account the compliance and correction of the clamping force during handling. The execution of the control involves the collaboration of the two arms for coordinated manipulation and adaptation to the material and the human environment (cobotics)

Повний текст джерелаThis PhD thesis explores the development and implementation of URNik-AI, an AI-powered automated depalletizing system designed to handle cardboard boxes of varying sizes and weights using a dual-arm humanoid torso. The primary objective is to enhance the efficiency, accuracy, and reliability of industrial depalletizing tasks through the integration of advanced robotics, computer vision, and deep learning techniques.The URNik-AI system consists of two UR10 robotic arms equipped with six-axis force/torque sensors and gripper tool sets. An ASUS Xtion RGB-D camera is mounted on Dynamixel Pro H42 pan-tilt servos to capture high-resolution images and depth data. The software framework includes ROS Noetic, ROS 2, and the MoveIt framework, enabling seamless communication and coordination of complex movements. This system ensures high precision in detecting, grasping, and handling objects in diverse industrial environments.A significant contribution of this research is the implementation of deep learning models, such as YOLOv3 and YOLOv8, to enhance object detection and pose estimation capabilities. YOLOv3, trained on a dataset of 807 images, achieved F1-scores of 0.81 and 0.90 for single and multi-face boxes, respectively. The YOLOv8 model further advanced the system's performance by providing keypoint and skeleton detection capabilities, which are essential for accurate grasping and manipulation. The integration of point cloud data for pose estimation ensured precise localization and orientation of boxes.Comprehensive testing demonstrated the system's robustness, with high precision, recall, and mean average precision (mAP) metrics confirming its effectiveness. This thesis makes several significant contributions to the field of robotics and automation, including the successful integration of advanced robotics and AI technologies, the development of innovative object detection and pose estimation techniques, and the design of a versatile and adaptable system architecture
