One of the most pressing issues in the field of mobile robotics is that of power delivery. By being fundamentally unattached to the environment, these systems often employ batteries. However, this can have some limitations related to cost, battery life etc.; a promising approach is that of powered floors, where a specially designed contact array is connected to the robot, and slides on a surface in which conducting bands are laid out, providing a continuous and uninterrupted electrical connection. In this paper, we provide a complete framework for the analysis and synthesis of these systems, to be used in the field of mobile robotics. We study the problem both in terms of feasibility and in quantitative terms; in particular, we illustrate a methodology related to n-sided polygons which takes into account a fuzzy representation of the bands, useful to analyze tolerances in the bands boundaries or in the position of the individual brushes. We support the theoretical framework with both numerical and experimental campaigns, and compare the results with existing state-of-the art solutions. Finally, we discuss possible further developments.

One of the most pressing issues in the field of mobile robotics is power delivery. In the past, we have proposed a powered floor based solution. In this article, we propose a system which combines a powered floor with a robot pose estimation system. The floor on which the mobile robots stand is composed of an array of interdigitated conductors that provide DC power supply; the stripes of conductors are interwoven similarly to what happens in a carpet, thus creating a sort of checkerboard of positive and negative pads. The robots are powered through sliding contacts. The power supply voltage is modulated with a binary encoding that uniquely identifies each conductor stripe power line; in this way, each robot is able to self-localize, by exploiting the information coming from the contacting pins. We describe the theoretical framework that allows concurrent power delivery and localization (with error boundaries). Then, we present the experimental evaluation that we performed using a prototype realization of the proposed powered floor system.

“…Due to the lack of contact, this system has advantages such as ease of use, high safety, high reliability, low maintenance cost, and long service life. This technology is used for applications such as electrical vehicles, consumer electronics, and biomedical applications where the conventional wired system is undesirable (Hasanzadeh and Vaez-Zadeh, 2015;Tang and Cheng, 2020;Keerthi et al, 2018). The basic principle of the electromagnetically coupled resonance based WPT system is that two coils with the same resonant frequency can efficiently transfer energy (Agcal et al, 2016).…”

In this study comparisons of different compensation topologies are investigated for two coil resonant wireless power transfer systems. Compensation circuits are examined individually according to system parameters such as efficiency, equivalent impedance, frequency, load resistance, and phase angle. This paper aims to compares the system variables in order to address the constraints in the system applicability regarding the compensation topology selection in Wireless Power Transfer (WPT) systems. Topology selection schemes related to circuit parameters are given. The main motivation of this study is that it presents a suitable topology selection scheme and flow diagram according to applications with various voltages, currents, power and loads. Simulations performed for four main topologies under various load conditions concludes that choosing the proper compensation topology for appropriate load is essential. Simulation studies are carried out with the Simulink software. The results obtained from here are validated with both Matlab calculation codes and C # calculation codes. The analyses according to the frequency in various load conditions have shown that variation of efficiency depends on the compensation topology of the receiver side. Moreover, in this study, it has been revealed that the topology of the transmitter side only affects the equivalent impedance together with the amount of power drawn from the input hence it has no effect on the efficiency and load characteristics. Consequently in the case of working with low load resistance such as an electric vehicle or mobile phone charging, topologies with series compensation on the receiver side can be preferred. Correlatively, topologies with parallel compensation on the receiver side can be evaluated as suitable for high load resistance, low current, and low power operations such as biomedical appliance charging.
