In a measurement system, new representation methods are necessary to maintain the uncertainty and to supply more powerful ability for reasoning and transformation between numerical system and symbolic system. A grey measurement system is discussed from the point of view of intelligent sensors and incomplete information processing compared with a numerical and symbolized measurement system. The methods of grey representation and information processing are proposed for data collection and reasoning. As a case study, multi-ultrasonic sensor systems are demonstrated to verify the effectiveness of the proposed methods.

Theoretical studies and experiment analysis of time-domain symmetrical configuration two-probe method are provided in this paper, and the method's feasibility and error separation's precision are discussed. Conclusions can be drawn from the results of simulation and experiment that measurement precision and repeat precision of two-probe method is a little higher that of single-probe method. Though radial random errors can not be separated entirely, the measurement theory of symmetrical configuration two-probe method is simple, and the measurement equipments' precision can be easily ensured. In addition, the data processing can be done directly in time-domain, which is more practicable. Two-probe method is useful in practical measurement. High accuracy can be ensured, especially in the case of measuring the shape errors of big parts with general precision. ©2010 IEEE.

6D pose estimation of 3D object is an important task in robotics, which allows the robot to determine object's position and orientation in pick-And-place applications. This paper proposes a solution for 6D pose estimation using RGB-D camera and 6-DOF robot. The main algorithm is the Point Pair Feature (PPF) that helps to find the position and orientation of the object. The authors also give some improvements based on the original algorithm. The accuracy of PPF algorithm's will be evaluated in 5°, 5cm. For communication between the robot and the computer, we build a UDP-based protocol program that is suggested by Yaskawa. In addition, we provide a Graphical User Interface (GUI) to support the control and observation of the execution. © 2022 IEEE.

This paper describes a data logger system based on microcontroller (wind speed, wind direction, humidity and temperature) and storing data in the SD (Secure Digital) memory card. The evaluation of the wind potential available at a particular site is needed to determine the viability or not the wind turbine installation. However, data acquisition systems for wind prospecting and monitoring of the wind power plants use high cost and precision sensors (anemometer, thermo-hygrometer, wind vane). Therefore, this low cost data acquisition system presented in this paper has characteristics of some commercial data loggers and it is appropriated to study of the feasibility of the installing micro wind turbines for distributed generation. © 2016 IEEE.

This paper presents a mobile robot aided self deploying wireless sensor network aiming to detect radiation leaks and to measure radiation levels, and explains design considerations to prolong network life. Special attention is given to the factors which are important for the specific requirements of radiation leak detection. Wireless sensor networks (WSNs) provide numerous benefits to applications with low duty cycle, such as environmental monitoring, event detection, etc. However, the realization of these potential benefits directly depends on energy efficient and reliable communication and coordination capabilities of the deployed system. In this study, challenges of WSNs, deployment strategies using mobile robots, and energy harvesting techniques to maximize lifetime of WSNs are discussed. Also, a comparison of two different exploration strategies is shown with the results of our own application developed in C#. Main contributions of this study are discussions on mobile robot aided WSN deployment strategies and energy harvesting techniques to maximize WSN lifetime. © 2012 IEEE.

In the paper, a cloud computing based intelligent scheduling system for manufacturing quality is proposed. Most of scheduling system is only considered producing time but manufacturing quality. It is very important to focus on manufacturing quality for the industry upgrade. The factors of manufacturing quality are product, equipment, material and human. It makes higher cost for scheduling the flexible manufacturing system. So we develop the cloud computing-based intelligent scheduling system by using artificial neural network and optimized layout method for manufacturing quality in the research. The architecture of the intelligent scheduling system contains: (1) Cloud database structure. (2) Intelligent scheduling engine. (3) Real-time human-machine interface. SQL Azure is used as the cloud database for scattering and storing data. And the intelligent scheduling engine contains the intelligent sequence score system of the products, the optimized layout system and the monitoring system of available resources. By using Visual C#, we can program a human-machine interface with real-time data updating. So that we can see real-time scheduling states of manufacturing by the human-machine interface at any time everywhere. We get good performance from the results of the experiment in the intelligent scheduling system considering manufacturing quality. It is important to develop a cloud computing-based intelligent scheduling system for manufacturing quality because of the advantages of production fluency, low cost, just good quality and flexible management. © (2013) Trans Tech Publications, Switzerland.

control of underactuated free floating robots in space

Control of underactuated free floating robots in space

Proceedings of the 1998 IEEE/RSJ International Conference on Intelligent Robots and Systems. Part 2 (of 3)

The underactuated free floating robot in space is nonlinear systems where velocity and acceleration constraints are both nonintegrable, therefore it is a second-order nonholonomic system. Some of the existing non-holonomic control methods will not be directly applicable to such systems as it is extremely difficult, if not impossible, to find the control Lie brackets. In this paper, by investigating the system dynamics in dept., we propose a simple velocity-based method to control the unactuated joints and a multi-step composite strategy to implement orientation tracking tasks. The proposed algorithm is of significance in controlling of space robots when some joints fail to function, or they are intentionally set to be passive for energy efficiency and safety purposes.

The early days of 3D graphics computing were marked by extremely expensive and highly sophisticated hardware and software. Terms like ubiquitous computing and 3D on handhelds were unthinkable. But the development of obliging common standards like OpenGL, for example, together with rapidly improving graphics technology turned the coin, and now everybody demands for high-performance user interfaces on his everyday-computing environment. Game development industry focuses on mobile technology. Automotive engineering introduces multimodal interfaces and entertainment systems for next generation cars. Although all industrial sectors ask for high performance graphics, they often focus on different aspects due to the still existing limitations of their graphics devices. This leads to a demand to revise and also optimize the graphics standards in order to make them suitable for special embedded and small-scale devices. This paper will present the state of development of OpenGL-ES, a 3D-standard for embedded graphics, its difference to regular OpenGL and its benefit for small-footprint interactive systems. Special aspects of safety-critical devices in avionics and military applications will be discussed. Actual applications and research will be referenced. © 2006 IEEE.

In the last few decades, it has been observed that accidental patients are getting more severe injuries while handling the injured person due to spinal/neck injuries or not enough emergency support at the spot. Thus, we designed a portable device to support the human cranial and neural system in the neck region, which includes the top vertebral bones and major nerves. To avoid damaging the major nerve, emergency support staff must handle the unconscious individual with extreme caution after they have been hurt. If it is injured, the individual may experience compression, laceration, or contusion of the spinal cord, which may result in a coma, paralysis, or long-term repercussions on the neurological system. This article provides the solutions and discusses the challenges of implementing the GPS-based emergency cervical support system that is capable of activating an airbag in life-threatening circumstances. The system is developed with the help of various sensors and a digital controller. Explaining the design steps and the assembly arrangement will help the neck area be restrained and keep it as straight as possible. Hence, that saves the injured person from menacing injuries. © 2024 IEEE.
