“…In Hernandez-Martinez et al, 4 an auction-based assignment method is presented, where AGVs bid to obtain the transport of a given product. The allocation is made based on the characteristics of each AGV in terms of location, capabilities and execution time.…”

“…2,3 The conveyor systems used for transportation tasks are no longer suitable for FMS, especially with the requirements of routing flexibility. 4 Thus, in the Handling Material System (HMS), mobile manipulators are used to ensure transportation tasks to be able to execute a full transportation task composed at least by three elementary operations (loading products on mobile robot, transporting the product to destination and unloading product from the mobile robot). 5 In order to increase the flexibility of such devices, the European project CoRoT proposes to develop a modular mobile manipulator composed of two intelligent elements (a robotic arm and a robotic mobile base) able to be separated and gathered in a short time.…”

“…The path planning is an important problem studied by several research work for single or multi robots systems. The selected path in complex systems affects directly the duration of the transportation, 4,5,8 is interested by the energy management of mobile robots and the optimisation of the charge station placement, knowing that the idle state can be considerable for this kind of device. Other researches focus on the assignment of tasks to manipulators.…”

The use of mobile manipulators for transportation tasks has provided solutions to several flexibility problems in manufacturing systems. Mobile manipulators are mobile entities equipped with robotic arm for loading and unloading of parts and an Automated Guided Vehicle (AGV) for their transport. In order to increase further the flexibility of these systems, the mobile manipulators could be modular, where their two entities are able to work together or separately. The assignment of transportation operations to different smart entities working together is a complex problem, which has not been addressed sufficiently in the literature. This paper proposes a two-stage decision approach for transportation task assignment, which is based on auction mechanism and a coalition formation process modeled with integer linear programming. A real use case has been implemented to test the efficiency of the proposed method. The proposed approach gives promising results that are discussed.

“…Formation control is a fundamental motion coordination problem in mobile robots [1]. It can be found in transportation [2], surveillance [3], search and rescue [4], logistics [5], material handling in manufacturing cells [6], mobile sensor networks [7], and area coverage [8]. The primary purpose of formation control is to track group trajectories while maintaining desired inter-robot spacing defined by relative positions, distances, or angles [9,10].…”

This paper proposes a distance-based formation control strategy with real-time disturbance rejection for omnidirectional mobile robots. The introduced control algorithm is designed such that the leader tracks a desired trajectory while the follower keeps a desired distance and formation angle concerning the leader. In the first step, the evolution of distance and formation angle is obtained from a perturbed second-order dynamic model of the robot, aided by a general proportional integral observer (GPIO), added to estimate unwanted disturbances. Then, the control law is designed for both robots via the active disturbance rejection control (ADRC) methodology, which only depends on the position, distance, and orientation measurements. A numerical simulation compared with a robust controller exhibits the system’s behavior. Furthermore, a set of laboratory experiments is conducted to verify the performance of the proposed control system, where a motion capture system is used as a proof of concept. In this context, this is considered a previous step for further experimentation with onboard sensors.

“…The flexible manufacturing system (FMS) is composed of a unified information control system, material handling system, and digital control processing equipment, and the FMS can adapt to the transformation of processing objects. 2 Also, it can automatically adjust and achieve high-efficiency batch production of a variety of workpieces within certain limits and modify products to meet market demand timely. The FMS has advantages of high equipment utilization rate, relatively stable production capacity, high product quality, flexible operation, and large product adaptability.…”

The product quality and production efficiency of a flexible manufacturing system have improved effectively by introducing the computer management and the material transportation system. The flexible manufacturing system performance greatly depends on the performance of the material transportation system. As a mobile robot controlled by a central controller, an automated guided vehicle has a strong ability for material transportation. This article studies a dynamic scheduling problem in a shop floor, where machines and automated guided vehicles run at a specified speed and specifies a mathematical model for the dynamic scheduling problem with the goal of makespan minimization. Meanwhile, inspired by the hormone secretion principle of the endocrine system, a bio-inspired scheduling optimization approach is developed to solve the dynamic scheduling problem in the flexible manufacturing system. To verify its practical application, the bio-inspired scheduling optimization approach and other scheduling approaches are tested, and the results illustrate that the bio-inspired scheduling optimization approach has better scheduling performance as well as optimizes the quality of integrated and real-time scheduling of machines and automated guided vehicles.
