This book covers a variety of topics in the field of mechatronics engineering, with a special focus on innovative control and automation concepts for applications in a wide range of field, including industrial production, medicine and rehabilitation, education and transport. Based on a set of papers presented at the 1st International Conference “Innovation in Engineering”, ICIE, held in Guimaraes, Portugal, on June 28-30, 2021, the chapters report on cutting-edge control algorithms for mobile robots and robot manipulators, innovative industrial monitoring strategies for industrial process, improved production systems for smart manufacturing, and discusses important issues related to user experience, training and education, as well as national developments in the field of mechatronics. This volume, which belongs to a three-volume set, provides engineering researchers and professionals with a timely overview and extensive information on trends and technologies behind the future developments of mechatronics systems in the era of Industry 4.0.
Indoor GPS System for Autonomous Mobile Robots Used in Surveillance Applications: Development of urban areas has created a need for stable, reliable and cost-efficient indoor GPS systems based on regularly available technologies. Such systems already exist and are in use. This paper proposes such a system with an emphasis on ease of use, long-term reliability or maintenance free through network redundancy techniques as well as an open-source architecture. The proposed architecture uses a Bluetooth/Wi-Fi’s RSSI (Received Signal Strength Indicator) parameter as relative to multiple mobile and fixed nodes to determine the distance to an object. The nodes, both mobile and fixed, are purpose-built for the object of this study and feature multiple other peripherals, as described in the paper. The basic implemented model of these nodes is also described in the paper.
Experimental Investigation of the Effect of Mass Load on Flight Performance of an Octorotor and Dodecarotor UAV: In this study, the flight performance of a universal Vertical take-off and landing (VTOL) unmanned aerial vehicle (UAV) with 12 and 8 rotors was examined under load and no-load conditions. Thanks to its universal structure, experimental studies with 8 and 12 rotor UAVs were performed on the same platform and under the same conditions. In addition, the controller parameters were kept the same for both vehicle types in order to observe the effect of the mass load only. Hierarchical PID controllers are used as the controller architecture to control the orientation and position of the both vehicles. The flight performance of both vehicles was examined in three stages as take-off, trajectory and landing. Settling time, rise time parameters and position errors were used to benchmark the flight performance of the both vehicles. The results show that the performance of the 12-rotor vehicle is superior, especially in terms of trajectory tracking performance although the take-off and landing performance is very close to each other for both vehicles. This was observed more clearly under load conditions.
