Practical investigations in robot localization using ultra-wideband sensors

Robot navigation is rudimentary compared to the capabilities of humans and animals to move about their environments. One of the core processes of navigation is localization, the problem of answering where one is at the present time. Robot localization is the science of using various sensors to inform a robot of where it is within its environment. Ultra-wideband (UWB) radio is one such sensor technology that can return absolute position information. The algorithm to accomplish this is known as multilateration, which uses a collection of distance measurements between multiple robot tag and environment anchor pairs to calculate the tag’s position. UWB is especially suited to the task of returning precise distance measurements due to its capabilities of short duration, high amplitude pulse generation and detection. Decawave Ltd. has created an UWB integrated circuit to perform ranging and a suite of products to support this technology. Claimed and verified accuracies using this implementation are on the order of 10cm. This thesis describes various experiments carried out using Decawave technology for robot localization. The progression of the chapters starts with commercial product verification before moving into development and testing in various environments of an open-source driver package for the Robot Operating System (ROS), then the development of a novel phase difference of arrival (PDoA) sensor for three-dimensional robot localization without an UWB anchor mesh, before concluding with future research directions and commercialization potential of UWB. This thesis is designed as a compilation of all that the author has learned through primary and secondary research over the past three years of investigation. The primary contributions are: 1. A modular ROS UWB driver framework and series of ROS bags for offline experimentation with multilateration algorithms. 2. A robust ROS framework for comparing motion capture system (MoCap) ground truth vs sensor data for rigorous statistical analysis and characterization of multiple sensors. 3. Development of a novel UWB PDoA sensor array and data model to allow 3D localization of a target from a single point without the deployment of an antenna mesh

Mass introduction of electric passenger vehicles in Brazil: impact assessment on energy use, climate mitigation and on charging infrastructure needs for several case studies

Mobility has proved to be a major challenge for human development, especially in urban centers worldwide, where more displacement is required, since fossil fuels consumption is increasing as well as greenhouse gas (GHG) emissions, causing air quality degradation and global warming. The predicted population increase in cities tends to increase the demand for mobility and to further exacerbate those impacts. Therefore, sustainable transport is key for the future of mobility, and electric vehicle (EV) has emerged as a recognized sustainable option. However, there are many electric vehicle barriers diffusion. This research aims to contribute to the diffusion of EV in Brazil, by assessing: 1) whether EV is a more sustainable technology when compared with ethanol vehicle; 2) the impacts of the expansion of electric mobility on CO2 emissions, in Sao Paulo; 3) how to overcome the barriers for the charging infrastructure deployment at the municipality level, in Sao Paulo, Rio de Janeiro and Belo Horizonte; and 4) key challenges and opportunities from the mass adoption of EV in Brazil. A plethora of different methods were used, including scenario analysis, multi-criteria decision methods, geographic information systems and SWOT analysis. Main results point to EV as the best technology to mitigate passenger transport related CO2 emissions in Brazil, due to its low carbon footprint. In Sao Paulo, this option could reduce around 11 MtCO2 by 2030 and save 6,200 billion USD in energy with the replacement of 20 percent of gasoline cars with EV. To meet 1 percent of EV's market share, Sao Paulo, Rio de Janeiro and Belo Horizonte together will need around 6,500 charging stations concentrated in around 1/3 of their territories (level 2). Brazil may likely have up to 10 percent of EV penetration by 2030, with the diffusion taking place mostly in southeastern municipality. Ethanol, lack of electric mobility public policy, non-urbanized like subnormal agglomerates, and risk areas, like flood hazard, are major obstacles for EV diffusion in Brazil

EG-ICE 2021 Workshop on Intelligent Computing in Engineering

The 28th EG-ICE International Workshop 2021 brings together international experts working at the interface between advanced computing and modern engineering challenges. Many engineering tasks require open-world resolutions to support multi-actor collaboration, coping with approximate models, providing effective engineer-computer interaction, search in multi-dimensional solution spaces, accommodating uncertainty, including specialist domain knowledge, performing sensor-data interpretation and dealing with incomplete knowledge. While results from computer science provide much initial support for resolution, adaptation is unavoidable and most importantly, feedback from addressing engineering challenges drives fundamental computer-science research. Competence and knowledge transfer goes both ways

Proceedings. 9th 3DGeoInfo Conference 2014, [11-13 November 2014, Dubai]

It is known that, scientific disciplines such as geology, geophysics, and reservoir exploration intrinsically use 3D geo-information in their models and simulations. However, 3D geo-information is also urgently needed in many traditional 2D planning areas such as civil engineering, city and infrastructure modeling, architecture, environmental planning etc. Altogether, 3DGeoInfo is an emerging technology that will greatly influence the market within the next few decades. The 9th International 3DGeoInfo Conference aims at bringing together international state-of-the-art researchers and practitioners facilitating the dialogue on emerging topics in the field of 3D geo-information. The conference in Dubai offers an interdisciplinary forum of sub- and above-surface 3D geo-information researchers and practitioners dealing with data acquisition, modeling, management, maintenance, visualization, and analysis of 3D geo-information
