Autonomous Ground Vehicles play a vital role in various industries, necessitating efficient route planning for mission success without human intervention. This study examines two metaheuristic optimization approaches, Genetic Algorithms and Ant Colony Optimization, within the context of route planning for these robotic entities. The comprehensive methodology utilizes the designs of these metaheuristic methods, and a comparative analysis is conducted through simulated experiments in diverse environments. Thefindings unveil that Genetic Algorithms excel in simple terrains; while Ant Colony Optimization demonstrates robust exploration capabilities in complex environments with obstacles and additional constraints. This underscores the importance of selecting the appropriate metaheuristic based on specific mission requirements and environmental conditions. The research furnishes insights to designers and operators, enabling informed decisions in route planning strategy selection, thereby enhancing the efficiency and safety of autonomous robotic operations across various scenarios.

In recent years, a large number of works have been presented that seek to solve the problem of road following by autonomous surface vehicles (ASV). In this sense, a non-linear guidance algorithm (NLGL), which has emerged in recent years for use in aerial vehicles, is presented as an interesting option for path tracking by marine vehicles as it does not use the yaw angle to achieve its objectives. control objectives. The biggest problem that these vehicles present when following paths is the influence of environmental disturbances on them, mainly sea currents and wind. To provide a solution to this problem, this paper presents a guidance and control scheme to achieve the following of straight paths by marine vehicles. It presents a cascade structure with an internal yaw velocity loop, which presents a PI controller as the main element, and the NLGL algorithm in the external loop. Thus, achieving that the vehicle follows a straight path with zero error without the need to measure the yaw angle and avoiding the implementation of an integral action in the external loop. An analysis is made of how the marine currents and the wind influence this system from the linearization of the presented scheme, in addition to a stability analysis of the scheme is presented. Finally, the results of simulation and real experiments of the implementation of this scheme in a small ASV are presented, where the vehicle converges to the desired trajectory with precision in the presence of environmental disturbances.

Introduction: The text departs from a theoretical review in order to distinguish two specific dynamics involving the use of commercial tools by activists on the one hand, and the development of autonomous technologies driven by social movements themselves on the other. Objectives: The aim of this article is to define various logics of digital activism by engaging critically with several scholar contributions that, generally through a historical analysis, allow us to establish theoretical distinctions and recognize differentiated logics of action when it comes to determining how social movements actually use digital technology. In the paper, critical engagement with the literature is examined against our empirical findings to challenge pre-existing assumptions, as well as evolutionary approaches sometimes observed in some of these contributions. The text also makes a point of transcending closed historical stages. Conclusions: The article’s conclusions point towards a multidimensionality of factors (pragmatic-utilitarian, strategic-tactical and ideological/identity-related) regulating the ways in which social movement leverage technology.

This research study aims to determine the impact of implementing a new bicycle route network proposal on the operability of private vehicles in the city of Manizales (Colombia). Road infrastructure interventions, associated with the implementation of sustainable autonomous transport systems, affect the operability of automotive transport modes because of structural requirements for both safety and operation. The methodology includes applying transport infrastructure supply models as an evaluation basis. This is supported by geographical accessibility, coverage, and geospatial impact analyses. The results show that implementing the proposal generates up to a 3% variation in average travel times for private vehicles. It is concluded that accessibility conditions do no change significantly for private vehicle users. [ABSTRACT FROM AUTHOR]

The accidents in which autonomous vehicles have been involved, and the legal problems arising from these events are the subject of this work. If we take into account the volume of vehicles that travel daily on our roads, as well as the number of accidents, we can intuit the negative consequences of the implementation of an autonomous technology without previously having a legal regime adapted to these new risks. This work therefore aims to focus on the possible legal resources to solve the regulatory mismatch, --related to the civil liability regime--, analyzing, on the one hand, current traditional systems and, on the other, various innovative systems proposed from different areas.

The exponential advance of artificial intelligence and all other technologies unleashed within the so-called Fourth Industrial Revolution have put us at the gates of a categorical turn for humanity. We are developing computers capable of self programming and being autonomous to the point that the initial programming has nothing to do with its subsequent evolution. That leads us to consider several dilemmas. On the one hand, the machines, endowed with "freedom", will end humanity or at least dehumanize it in such a way that by the hand of a mathematical algorithm, they will decide how the human race should be, which person is fit or not for life and what a turn science should take. We will become useless in a robotic world. On the other hand, by obeying a logical approach, humanity could be better, since there would be no room for evil. Human beings would have more time to travel, learn, think, play, love and all the wonders of the spirit, while the machines work and produce for us. There would be no pedophilia, racism or envy. However, could human creativity become "super-creativity" by harnessing the greater capacity of artificial intelligence? Would people's creativity simply be displaced by superior machine intelligence? Would we be playing God, inventing intelligent beings, but without conscience? Would we end humanity with ourselves for the unstoppable pride of our race? Would we have sufficient capacity to develop this technology in a controlled manner for our service? Daring questions but must find an answer. [ABSTRACT FROM AUTHOR]

An AUV is an underwater vehicle that carries its own power supply and computational units. The HRC-AUV is a prototype develop by "Center for Navy Researching and Development" (CIDNAV) for undersea researching. In this paper is presented the implementation of a navigation system based on the nonlinear dynamical model for the HRC-AUV which allows to estimate sea currents magnitude and direction in the operation environment improving the navigation results. The results are validated through simulation using the 6 degrades of freedom (DOF) nonlinear model obtained for the HRC-AUV and using data sets obtained in experimental sessions directly from the vehicle.

Based on the premise that the car has substantially transformed urban life, the aim of this article is to investigate the dimension of the ideas that residents of two neighborhoods in Cali (Colombia) have about their mobility and means of transportation. For this purpose, the analysis will be grounded on a Durkheim-based interpretation of social representation, understanding that this is not an autonomous dimension configured with its back turned against factual reality; rather, it interacts, structures, and is structured by social practices. Three representations will finally converge in the configuration of automotive logic in the residents of the two middle-class neighborhoods analyzed, which could be summarized as follows: the desideratum of sustainable mobility, the automobile as an efficient device, and the mystification of driving.

The development of autonomous vehicles is a subject of great interest in the international scientific community. For the accomplishment of missions without human intervention it is vitally to have an algorithm or guiding law. In this paper we present the results obtained by simulation with the guidance algorithm based on distance L1, during the tracking of straight and circular paths by an autonomous aerial vehicle (UAV). The algorithm produces a lateral acceleration command that is interpreted by the balancing controller to achieve convergence to the path. The results of the simulation demonstrate the good performance of the algorithm, for both straight and circular paths. [ABSTRACT FROM AUTHOR]
