The challenges imposed on Manufacturing Systems (MS), given the demands of a dynamic and competitive market, instigates the development of new technologies to promote the reduction of production costs, increase productivity and ensure the level of quality established by the company. Such technologies applied in MS create demands for new paradigms for the design of control systems, mainly about the integration of automated systems, such as multifunction machines, flexible machining centers, intelligent robotic conveyor systems, and the integration of information systems, production planning and management, and manufacturing execution. The main purpose of control system modeling is to represent a real system using conceptual models to visualize, predict and simulate the desired dynamic behavior of the system. This article presents some modeling tools for control systems capable of adequately representing a manufacturing system with all its requirements and intrinsic characteristics, supported by formal methods for structured modeling of the control system.

Emerging commercialised anthropomorphic hand prostheses have two main categories: expensive ones with remarkable functionality afforded by complex control systems, and inherently inexpensive ones with basic gripper-like aptitudes that do not fully fulfil the basic physical and emotional requirements of upper-limb amputees or individuals with upper limb congenital defects. This paper aims to establish a middle ground between these two commercial alternatives by realizing a low-cost and highly functional robotic hand. All five digits of the proposed robotic hand are controlled by a single DC motor. This desirable feature is afforded by the implementation of under-actuation. The under-actuation in the fingers is achieved through four-bar linkages coupling with cartwheel flexure joints, which leads to not only shape adaptation, i.e., the ability to naturally adapt to the form of the article being grasped without the aid of intricate control systems, but also low cost due to the possibility of monolithic fabrication (e.g. 3D printing) and ease of control. The under-actuation in the palm system is implemented via the use of a differential pulley mechanism embedded thereof, which furthermore results in low cost by reducing the number of actuators and simplifying the control system. A simple and easy-to-use control system based on voice commands through a smart phone was also developed. It is envisaged that the proposed design can also be applied in various engineering environments to meet adaptability/under-actuation needs.

Pressure Observer

The nonlinear pressure observer this paper presents for pneumatic systems and observer-based approaches for controlling position and stiffness eliminate the need for pressure and force sensors. The observer estimates pressure in the pneumatic actuator chamber, acting instead of a sensor in a pressure-feedbackbased system. Conventional single-loop controllers are inadequate for pneumatic actuators because such actuators have high nonlinearities such as air compressibility and friction. Most advanced controllers providing better performance require full-state feedback, and using sensors to acquire data makes pneumatic control systems less cost-competitive than electric control systems. Combining our proposed pressure observer with other observers enables a position and stiffness control system to be designed for a two degree-of-freedom pneumatic manipulator. Force caused in contact between the manipulator and an external object can be obtained without using force sensors. Experimental results show that our observerbased approach reduces cost, enables high estimation performance, and ensures high control accuracy.

The advent of processor based controllers including the PLC has provided a low cost alternative for up gradation of control systems when faced with the challenges of maintenance and obsolescence. A project was undertaken at the Centre of Marine Engineering Technology of the Indian Navy to design, develop and test a PLC based controller for a Gas Turbine Generator as an alternative to the legacy relay logic based control system. The paper explains the methodology adopted towards the various stages of the development of the PLC based controller using Commercially-Off-The-Shelf (COTS) items. It also brings out the salient advantages offered as a result of this transformation.

The simultaneous optimum design for structural and control systems is very important to realize better performance, short lead time and low cost in the development of product. Previous researches on the simultaneous optimum design of these systems are mainly based on mathematical optimization or coupled computation by CAE which are based on point-based iterative calculation. On the other hand, it is general and essential that the required performances and the influence factors for them have some kinds of uncertainty especially in the initial design stage of structural design and uncertainty arising from the difference of real structural (mechanical) and mathematical models in the control system. In this research, for the expression of uncertainty, we use set-based method rather than point-based for processing these uncertainties. Also, generally, the design of the system has often multi-performances, whether structural system or control system. Then, how effective the set-based design method is to solve the simultaneous design problem is investigated, using simple examples of classical control and modern control. As a result, it is found that the applicability of the set-based design method is shown.

CANopen is a kind of higher layer protocol based on CAN, and it is widely used in industrial automation field, especially in distributed motion control systems. The paper presents an approach of realizing CANopen slave node. Microcontroller STC90C514RD is used as a core chip to design the control system; the design adopts CTM1050 as the CAN transceiver and uses SJA1000 as the CAN controller. And the system consists of a CANopen slave node, input module and output module. MicroCANopen, which is an open source protocol stack of CANopen, is transplanted to main controller so that the function of CANopen could be implemented. Moreover the experimental platform is built to test the design of the system. The results prove that the design is feasible and valid.

In order to help students be more interested in learning about programming both at school and at home, we have designed educational toys in the form of humanoid robot. In this paper, intelligent robot movement control systems are developed, thus the students can interact directly and learn programming on human robots. For building a low-cost humanoid robot, we modified low-cost robot toy, that is Robosapien from Wowwee by embbeding a control system. The control system is developed based on Raspberry Pi Zero W, which enables us to control Robosapien's movements wirelessly. This learning media is expected to enhance the student’s spirit of learning, especially in the field of robotics and programming. The main contribution of the research is the description and analysis of various design decisions during the development of this humanoid robot. In addition, it provides information about the main components for development and example for interacting with robots as learning media.

Proposed Model

As the need for efficient warehouse logistics has increased in manufacturing systems, the use of automated guided vehicles (AGVs) has also increased to reduce travel time. The AGVs are controlled by a system using laser sensors or floor-embedded wires to transport pallets and their loads. Because such control systems have only predefined palletizing strategies, AGVs may fail to engage incorrectly positioned pallets. In this study, we consider a vision sensor-based method to address this shortcoming by recognizing a pallet’s position. We propose a multi-task deep learning architecture that simultaneously predicts distances and rotation based on images obtained from a visionary sensor. These predictions complement each other in learning, allowing a multi-task model to learn and execute tasks impossible with single-task models. The proposed model can accurately predict the rotation and displacement of the pallets to derive information necessary for the control system. This information can be used to optimize a palletizing strategy. The superiority of the proposed model was verified by an experiment on images of stored pallets that were collected from a visionary sensor attached to an AGV.
