Book Description
Software testing is becoming increasingly important because more and more products are software-intensive. Cars, for example, contain more and more control software (ECUs) that are networked with each other. With new rail vehicles, software problems delay commissioning by months, even years, because the different components are not coordinated with each other. A timely system test would help, but there is a lack of time and resources. The functionality of the software is simply too great. So, you must automate. Automation is not only necessary for the execution of tests, but above all for the generation of suitable test cases. This is possible with Combinatory Logic, the Analytic Hierarchy Process (AHP), and Quality Function Deployment (QFD). When today’s cars use map services from the cloud, or their own sensors, for an Advanced Driving Assistance System (ADAS) to perform driving decisions; or when in the future an autonomous car meets another; or with truck platooning; or when adding a new, previously unknown device to an IoT orchestra, the original base system expands its functionality. Therefore, such an expanding system needs being retested before it can do decisions with the potential of affecting harm to humans or things, after each update, after each learning. This is Continuous Testing during operation; it supplements Continuous Delivery and Continuous Integration. Disruptive innovations in automotive require an equally disruptive new approach to testing of software-intense systems. This requires moving from once-upon-a-time testing before release to autonomous real-time software & systems testing during operations, with indications to users and suppliers about the actual state and testing results. This book explains the theory and the implementation approach for a framework for Autonomous Real-time Testing (ART) of a software-intense system while in operation.

Book Description
An operational prototype of a ground vehicle that may be used as a test bed for future experiments in autonomous guidance, navigation, and control is developed. Key topics in the research include vehicle dynamics and modeling, inertial navigation, hardware/software integration, and system identification. The vehicle dynamics are derived from a simplified 3 degree-of-freedom (2 translational axes and 1 rotational axis) model, and inertial navigation equations are developed for the 2-dimensional, planar case. Descriptions of the hardware subsystems, which include the vehicle, onboard computer, sensors, actuators, and communications radio are presented. The execution of the real-time, onboard software used to perform control input/output as well as the ground station software application is outlined. Finally, the methodology and results of system identification experiments used to estimate the servo actuators and vehicle modeling parameters are given. Field testing demonstrated successful execution of the onboard and ground station software applications as well as the sensors and actuators subsystems. The vehicle was operated open-loop by uploading a sequence of steering and throttle commands from the ground station, and the sensor measurement data was recorded. The recorded data was used to estimate modeling parameters of the servo actuator mechanisms and the vehicle. The servo actuator models obtained from identification resulted in good matching between the simulated and physical responses with little deviation. The estimated vehicle parameters obtained from identification also resulted in good matching between the simulated and physical responses. Deviations between the simulated and physical responses are likely due to measurement errors present in the calculation of the vehicle states. The results of this research provide a proof-of-concept and demonstrate the viability of constructing an operational platform for vehicle autonomy.

Book Description
"Research and experiments on ... Autonomous Navigation Schemes and Algorithms need an efficient test-bed for objective performance analysis. These algorithms often require sensor inputs from the systems such as the speed and steering sensors to apply feedback control action. An efficient test-bed provides status of all sensors and records of all previous sensor values is very desirable. This work involves developing for such a test-bed to support research on Autonomous Navigation schemes and Algorithms involved in these applications. Different approaches are analyzed and an optimum approach to design test-bed is implemented"--Abstract, leaf iii

Book Description
In a world suffering from an ageing population and declining birth rate, service robotics and mechatronics have an increasingly vital role to play in maintaining a safe and sustainable environment for everyone. Mechatronics can be used in the reconstruction or restoration of various environments which we rely upon to survive; for example the reconstruction of a city after an earthquake, or the restoration of polluted waters This collection of papers was originally presented at the 7th International Conference on Machine Automation, 2008, in Awaji, Japan, and covers a variety of new trends in service robotics and mechatronics. Service Robotics and Mechatronics showcases the latest research in the area to provide researchers and scientists with an up-to-date source of knowledge and basis for further study, as well as offering graduate students valuable reference material.

Book Description
Cyber-physical systems (CPSs) consist of software-controlled computing devices communicating with each other and interacting with the physical world through sensors and actuators. Because most of the functionality of a CPS is implemented in software, the software is of crucial importance for the safety and security of the CPS. This book presents principle-based engineering for the development and operation of dependable software. The knowledge in this book addresses organizations that want to strengthen their methodologies to build safe and secure software for mission-critical cyber-physical systems. The book: • Presents a successful strategy for the management of vulnerabilities, threats, and failures in mission-critical cyber-physical systems; • Offers deep practical insight into principle-based software development (62 principles are introduced and cataloged into five categories: Business & organization, general principles, safety, security, and risk management principles); • Provides direct guidance on architecting and operating dependable cyber-physical systems for software managers and architects.
