Self-localization of a robot is one of the most important requirements in mobile robotics. There are several approaches to providing localization data. The Ultra Wide Band time of Flight provides position information but lacks the angle. Odometry data can be combined by using a data fusion algorithm. This paper addresses the application of data fusion algorithms based on odometry and Ultra Wide Band time of Flight positioning using a Kalman filter that allows performing the data fusion task which outputs the position and orientation of the robot. The proposed solution, validated in a real developed platform can be applied in service and industrial robots.

Reducing the power consumption of wearable sensors is a very important issue in relation to the device usage time and form factor. However, continuous wireless communication to analyze the measured signal in real-time significantly increases the power consumption of the wearable sensor. In this study, we propose a wearable vibration sensor that operates with extremely low power through an embedded signal classifier, which exhibits high accuracy and low calculation load. We demonstrate cough detection through the proposed sensor system. The result exhibits an accuracy of 93.0%, which is 24.3% higher than the conventional embedded classification algorithm. Also, the proposed approach reduces the average power consumption of the wearable sensor by 8.8 times.

Photovoltaic energy production is one of the major parts for the shift of our societies away from fossil fuels. Their irregular nature however poses a challenge for electricity grid managers. PV energy production forecasting and monitoring is extremely important to guarantee that the grid will be able to supply consumers at all times and without any unexpected interruptions. Our goal is to provide build a system that can effectively monitor all aspects of the operation of a PV power station and provide owners, facility managers and power grid administrators with high quality forecasts and operational insights. To better understand and evaluate our work, we test our system in a real-world case study from Arta, Greece, and benchmark the effectiveness of both mathematical models and machine learning based solutions with regards to both precision, consistency and trustworthiness.
