The Problem of Adhesion Methods and Locomotion Mechanism Development for Wall-Climbing Robots

This review considers a problem in the development of mobile robot adhesion methods with vertical surfaces and the appropriate locomotion mechanism design. The evolution of adhesion methods for wall-climbing robots (based on friction, magnetic forces, air pressure, electrostatic adhesion, molecular forces, rheological properties of fluids and their combinations) and their locomotion principles (wheeled, tracked, walking, sliding framed and hybrid) is studied. Wall-climbing robots are classified according to the applications, adhesion methods and locomotion mechanisms. The advantages and disadvantages of various adhesion methods and locomotion mechanisms are analyzed in terms of mobility, noiselessness, autonomy and energy efficiency. Focus is placed on the physical and technical aspects of the adhesion methods and the possibility of combining adhesion and locomotion methods

Through the Lens of Latinas: The Influences of an Out-of-School Time STEM Program

Science, Technology, Engineering, and Mathematics (STEM) have been the foundation for discovery and technological innovation in the United States. The United States considers STEM education as a national priority to compete in the global economy and protect the nation’s innovation ecosystem. The high demand for careers in STEM fields promotes the importance of STEM education. However, Latinos, as the fastest-growing ethnic group in the United States, face many challenges in STEM education relating to a lack of progress, degree attainment, and participation in STEM professions. This research aimed to explore the learning experience in an out-of-school (OST) STEM program, called “Girls in STEM”, and how it influenced Latinas’ self-efficacy, interest, and career development. The research focused on a single-case study of a STEM OST program in South Texas and utilized eight embedded cases to explore three research questions. The sample for this study consisted of 41 middle school and high school girls (grades 7 to 12) who had long-term participation experiences in the STEM program. The data for this qualitative study consisted of in-depth interviews, presentations from art-based activities, and visual arts. Followed by the case study design, the researcher purposefully sought in-depth information from embedded “unit of analysis,” which represented eight participants in the study (Yin, 2013, p. 23). Each case presented different aspects to answer research questions. The researcher analyzed interviews and art-based activities from participants through the lens of social cognitive theory and social cognitive career theory (Bandura, 2001; Lent et al., 1994). The findings explored Latinas’ learning experiences in an OST STEM program. Participants expressed the program created a beneficial learning environment for them, where they engaged in various activities and interacted with adults in the program. The learning experience, as the starting point of SCCT model, had influences on the development of self-efficacy and the formation of interests. In this study, the integration of different subjects, opportunities for collaborative work and conversational interactions with professionals, are three characteristics of cultivating Latinas’ interest in STEM. Additionally, many girls in this study noticed the stereotypes of women in STEM, and gender bias exists in many STEM fields. Socioeconomic status may limit Latina’s options and affected their career development

Hardware Architecture Review of Swarm Robotics System: Self-Reconfigurability, Self-Reassembly, and Self-Replication

Swarm robotics is one of the most fascinating and new research areas of recent decades, and one of the grand challenges of robotics is the design of swarm robots that are self-sufficient. This can be crucial for robots exposed to environments that are unstructured or not easily accessible for a human operator, such as the inside of a blood vessel, a collapsed building, the deep sea, or the surface of another planet. In this paper, we present a comprehensive study on hardware architecture and several other important aspects of modular swarm robots, such as self-reconfigurability, self-replication, and self-assembly. The key factors in designing and building a group of swarm robots are cost and miniaturization with robustness, flexibility, and scalability. In robotics intelligence, self-assembly and self-reconfigurability are among the most important characteristics as they can add additional capabilities and functionality to swarm robots. Simulation and model design for swarm robotics is highly complex and expensive, especially when attempting to model the behavior of large swarm robot groups.http://dx.doi.org/10.5402/2013/84960

Steering by Gazing: An Efficient Biomimetic Control Strategy for Visually-guided Micro-Air Vehicles

International audienceOSCAR 2 is a twin-engine aerial demonstrator equipped with a monocular visual system, which manages to keep its gaze and its heading steadily fixed on a target (a dark edge or a bar) in spite of the severe random perturbations applied to its body via a ducted fan. The tethered robot stabilizes its gaze on the basis of two Oculomotor Reflexes (ORs) inspired by studies on animals: - a Visual Fixation Reflex (VFR) - a Vestibulo-ocular Reflex (VOR) One of the key features of this robot is the fact that the eye is decoupled mechanically from the body about the vertical (yaw) axis. To meet the conflicting requirements of high accuracy and fast ocular responses, a miniature (2.4-gram) Voice Coil Motor (VCM) was used, which enables the eye to make a change of orientation within an unusually short rise time (19ms). The robot, which was equipped with a high bandwidth (7Hz) "Vestibulo-Ocular Reflex (VOR)" based on an inertial micro-rate gyro, is capable of accurate visual fixation as long as there is light. The robot is also able to pursue a moving target in the presence of erratic gusts of wind. Here we present the two interdependent control schemes driving the eye in the robot and the robot in space without any knowledge of the robot's angular position. This "steering by gazing" control strategy implemented on this lightweight (100-gram) miniature aerial robot demonstrates the effectiveness of this biomimetic visual/inertial heading control strategy

GUARDIANS final report

Emergencies in industrial warehouses are a major concern for firefghters. The large dimensions together with the development of dense smoke that drastically reduces visibility, represent major challenges. The Guardians robot swarm is designed to assist fire fighters in searching a large warehouse. In this report we discuss the technology developed for a swarm of robots searching and assisting fire fighters. We explain the swarming algorithms which provide the functionality by which the robots react to and follow humans while no communication is required. Next we discuss the wireless communication system, which is a so-called mobile ad-hoc network. The communication network provides also one of the means to locate the robots and humans. Thus the robot swarm is able to locate itself and provide guidance information to the humans. Together with the re ghters we explored how the robot swarm should feed information back to the human fire fighter. We have designed and experimented with interfaces for presenting swarm based information to human beings
