Abstract:
The objective of this paper is to discuss the probabilistic part of the model for robot group control applied in industrial applications. The proposed model is based on well-known concepts of Ubiquitous Computing [1] and enables contextual perception of a working environment. Compared with classical industrial robots, usually preprogrammed for a limited number of operations / actions, the system based on this model can react in uncertain situations and scenarios. The model combines ontology to describe the specific domain of interest and decision–making mechanisms based on Bayesian Networks (B

Compared with the single robot system, a multi-robot system has higher efficiency and fault tolerance. The multi-robot system has great potential in some application scenarios, such as the robot search, rescue and escort tasks, and so on. Deep reinforcement learning provides a potential framework for multi-robot formation and collaborative navigation. This paper mainly studies the collaborative formation and navigation of multi-robots by using the deep reinforcement learning algorithm.

Abstract:
Extensive research is being conducted on using robots to automate harvest. However, most of the existing research is focused on the realization of harvesting using a single robot, and there have been very few studies on harvesting and transporting crops from a smart-greenhouse perspective. In this study, we demonstrate that the work efficiency is higher when a plurality of harvesting and transporting robots are used in tandem for harvesting crops in a smart greenhouse, compared to that when a single robot is used. The harvesting and transporting speeds of these robots are modeled in accordance

In recent years, cooperative transportation systems using multiple mobile robots have been studied. The advantage will be to transport objects that cannot be dealt with by a single robot and transport them by using smaller robots. Although cooperative transportation by a group of robots has been studied, the conventional transportation targets are limited to objects whose posture is stable. In this paper, we propose a system in which robots pile up on each other to support an object, aiming at a system for more versatile object transportation, including unstable objects.

Considerable research is currently being conducted in the area of multi-robot systems. The most remarkable characteristic of these types of systems is that the robots are able to work cooperatively to complete a task that a single robot cannot accomplish by itself. This characteristic is essential in the investigation of the effect of the number of robots in a given system. Out of the various possible multi-robot tasks, a foraging task was chosen for these experiments.

Autonomously following a man-made trail in the wild is a challenging problem for robotic systems. Recently, deep learning-based approaches have cast the trail following problem as an image classification task and have achieved great success in the vision-based trail-following problem. However, the existing research only focuses on the trail-following task with a single-robot system. In contrast, many robotic tasks in reality, such as search and rescue, are conducted by a group of robots. While these robots are grouped to move in the wild, they can cooperate to lead to a more robust performance

Abstract:
AbstractControlling the formation of several mobile robots allows for the connection of these robots to a larger virtual unit. This enables the group of mobile robots to carry out tasks that a single robot could not perform. In order to control all robots like a unit, a formation controller is required, the accuracy of which determines the performance of the group. As shown in various publications and our previous work, the accuracy and control performance of this controller depends heavily on the quality of the localization of the individual robots in the formation, which itself depends on the ability of the robots to locate themselves within a map. Other errors are caused by inaccuracies in the map. To avoid any errors related to the map or external sensors, we plan to calculate the relative positions and velocities directly from the LiDAR data. To do this, we designed an algorithm which uses the LiDAR data to detect the outline of individual robots. Based on this detection, we estimate the robots pose and combine this estimate with the odometry to improve the accuracy. Lastly, we perform a qualitative evaluation of the algorithm using a Faro laser tracker in a realistic indoor environment, showing benefits in localization accuracy for environments with a low density of landmarks.

AbstractThis paper discusses how a microcontroller, like Arduino, can improve laboratory practice in Italian upper secondary school and change students’ attitudes towards STEM subjects. Since 2015, we started a close and fruitful collaboration with several high school teachers in the Marche region to introduce microcontroller programming to the physics lab. Notably, the project also involved teachers of other subjects, such as computer science, and with different backgrounds, for example electronic engineering, thus showing the inherently interdisciplinary character and versatility of Arduino. Students were engaged in hands-on activities, working in small groups of four to five people, supervised by learning assistants and teachers. Arduino was used to interface with sensors, to control the experimental setup, and for data acquisition. Finally, we could also make contact with robotics, by building a simple prototype of a rover.

Abstract:
Abstract This book chapter describes the most common control methods: the use of genetically resistant animals and the application of acaricides. Acaricides may be applied through dips, sprays or pour-on formulations as well as intra-ruminal boluses, ear tagscand footbaths. Resistance to acaricides is thecability in a strain of ticks to tolerate doses of acaricides that would prove lethal to most individuals in a normal population of the same species, and this is a major and growing problem. An anti-tick vaccine is commercially available for only a single tick species. Pasture management also has a role in integrated control. Each of these options would be about developing technologies, at best partial solutions to practical problems. As has been described above, a robust solution to the control of ticks and tickborne disease requires an understanding of tick distributions and economic impacts; the current and future effects of climate change; and the regulatory system and the production environment in which tick control is to be applied. ILRI has skills in all of these areas and a strong focus on at least one target group, the smallholder livestock farmer. Thus, ILRI has, in principle, not only the potential to develop new technologies but also the infrastructure and experience to facilitate their effective adoption.

Abstract:
AbstractWith the globalization of seed trade and transgenic variety development, the application of molecular technologies for seed quality gained more significance in both the internal and international markets. Besides germination, genetic purity and seed health are the two most important seed quality parameters that determine the planting value of a seed lot. Compared to the conventional methods of testing, molecular marker technologies are more efficient for quality analysis as these are more accurate, robust, abundant, and faster. Among the various markers, simple sequence repeats (SSRs), due to their genome-wide presence, reproducibility, multi-allelic nature, and co-dominant inheritance, have emerged as the best markers, for establishing varietal distinctness, identity, and variety/hybrid seed purity testing. With the advent of the next-generation sequencing (NGS) technology, single nucleotide polymorphic (SNP) markers also became widely popular, and the closest to being an ideal marker besides SSRs, in seed genetic purity testing. With large-scale GM crop cultivation, testing for the adventitious presence and trait purity are two added components of seed quality testing. The methods of GM seed quality testing include DNA-based (conventional and real-time PCR), protein-based (lateral flow test and ELISA), and bioassay-based technologies. DNA-based methods including PCR/real-time PCR assays have been successfully employed to detect the adventitious presence of transgenic seeds in seed trade especially at international level, as well as in the national gene banks for germplasm conservation. ISTA plays a prominent role in international harmonization and providing universal guidelines on use of different methods to detect GM seeds. The BMT group of UPOV and the Working Group on DNA Methods of the Variety Committee of ISTA, work in tandem to standardize suitable molecular techniques for establishing variety identity and purity testing, respectively. In the area of seed health testing also, molecular detection assays such as, PCR (nested PCR, multiplex PCR, real-time PCR), loop-mediated isothermal amplification (LAMP), and DNA microarray with many advantages over the conventional assays have been proven highly useful. However, there is a need to validate the usefulness of molecular markers through stringent multi-laboratory tests for their reproducibility before recommending them in routine seed purity and health testing.

Abstract:
AbstractSince 2010, Sweden has a Vision Zero policy on fire safety: no one should die or be seriously injured as a result of fire. Compared to the traffic safety model, however, the preconditions for successful implementation appear more immature and less convincing in the fire area. The purpose of this chapter is to illustrate, using the Vision Zero policy on fire safety as an example, how a Vision Zero initiative in a new area, where the conditions for governance may differ significantly from the area of inspiration, can be dealt with as a dynamic process to gradually establish credibility and effectiveness.Globally, fire is a significant cause of death and injury. The general trend is toward a slow decline, especially among middle-income and high-income countries. The decline may be due to successful fire safety efforts, but also to other conditions affecting it indirectly. Both risk-increasing and risk-reducing factors determine fire safety. Risk increasing factors include an ageing population, an increasing diversity of possible ignition sources, and a change in the composition and amount of combustible materials present in our homes. The risk-reducing factors include generally favorable socioeconomic and technological developments, including concrete societal actions directed against fire risks such as the promotion of smoke detectors and sprinkler systems.Fire safety is one of the oldest documented examples of societal risk management. City planning and construction were early influenced by fire safety considerations, while in contrast, the legal responsibility for residential fire safety has largely remained a private and individual matter. The situation is similar to the one that for long prevailed in the traffic sector, that is, the primary responsibility rests with the system’s users, not with its designers.The launch of the Vision Zero on fire safety in 2010 represented a clear boost in ambition. Along with the vision, a strategy intended to guide the work toward the visionary goal was also presented. The strategy included four items: information, technical solutions, local collaboration, and evaluation/research. Several actions were taken in line with the strategy, including a significant research effort and the development of a set of indicators to monitor progress.Ten years later, the research effort has brought new knowledge that puts previous perceptions into partly new light. The notion that survival depends on the individual’s personal capacities is strengthened. Adverse outcomes such as death and serious injury appear mainly linked to specific vulnerabilities of certain groups for medical and social reasons. Most fires are handled by the residents themselves without injuries and without assistance from Rescue Services; on the other hand, even minor fires can be fatal for vulnerable residents. This turns the problem framing toward social aspects rather than technical, since broad groups of residents lack the capacities needed, conflicting with the prevailing view that the individual should bear the primary responsibility.Other findings relate to the proven inefficiency of certain measures for groups at elevated risk and the need for re-thinking and innovations to meet the challenges ahead. This includes extended inter-sectoral collaboration on a broader spectrum of residential risks besides fire, threatening the same groups for similar social and medical reasons.This updated state of knowledge is now being used as a basis for renewing current national fire safety strategies. With reference to general principles of systems control, this chapter will discuss obstacles and challenges to establish a more robust and systematic national control of the fire problem in line with the Vision Zero policy. The appropriateness of launching Vision Zero policies in fields that are not yet ripe for systematic governance is also discussed. It is concluded that a Vision Zero initiative can still be meaningful and successfully pursued, provided that limitations in the ability to influence crucial elements in the system are openly identified and systematically addressed in a process in which strategical and policy developments interact with research and innovation.

Abstract:
An unknown environment could be mapped more efficiently by a group of robots than a single robot. The time reduction due to parallelization is crucial in complex area mapping. There are two general solutions used in the multi-robot mapping. In the first one, robots exchange raw data from sensors. The second approach assumes that each robot creates a local map independently that is exchanged with other robots and integrated. In this chapter, we present a 3D maps integration algorithm that utilizes overlapping regions in the feature-based alignment process. The algorithm does not need any initial guess about the transformation between local maps. However, for successful integration, maps need to have a common area. We showed that the implemented method is effective in various environments. The approach has been verified in experiments with wheeled mobile robots and using public datasets with octree-based maps.

Autonomous mobile robots have now emerged as a means of transportation in several applications, such as warehouse, factory, space, and deep-sea where direct human intervention is impossible or impractical. Since explicit communication provides a better and reliable way of multi-robot coordination compared to implicit communication, so it is preferred in critical missions, such as search and rescue, where efficient and continuous coordination between robots is required. Cooperative object transportation is needed when the object is either heavy or too large or needs extra care to handle (e.g., shifting a glass table) or has a complex shape, which makes it difficult for a single robot to transport. All group members need no participation in the physical act of transport; cooperation can still be achieved when some robots transport the object, and others are involved in, say, coordination and navigation along the desired trajectory and/or clear obstacles along the path. A distributed approach for autonomous cooperative transportation in a dynamic multi-robot environment is discussed.

Abstract:
In this chapter, we review our recent research in the area of collective robotics, and the problem of controlling multiple robots in the completion of common tasks. Our approach is characterized with a strong inclination for biological inspiration in which examples in nature — social insects in particular — are used as a way of designing strategies for controlling robots. This approach has been successfully applied to the study of three representative tasks, namely, collective box-pushing, collective construction, and collective sorting. Collective box-pushing deals with the purposeful motion of an object too large to be moved by a single robot and we rely on the group prey transport phenomenon found in ants to derive the necessary behaviors for accomplishing this task. Collective construction is concerned with the building of a geometric structure with the combined efforts of many individuals in parallel, without centralized control and we study a species of ant known to possess this capability, to model and control the process of creating a circular nest with multiple robots. Finally, in collective sorting the broad behavior in ants serves as the motivation behind designing robotic behaviors that depend on only local sensing in clustering objects of different types into separate piles. The success of our proposed approach is supported by both simulation and physical experiments using robots.

Abstract A kinematic structure based classification of six degree-of-freedom industrial robotic manipulators is introduced, and sample compact kinematic equations are given according to this classification. For the classification, one hundred industrial robots are surveyed. These robots are first classified into main groups and then into subgroups under each main group, and nine kinematic main groups, each having one to ten subgroups are obtained. The main groups are based on the end-effector rotation matrices and characterized by the twist angles. On the other hand, the subgroups are based on

Such motions constitute the 4-dimensional (4-D) Schoenflies subgroup of the 6-D displacement group. The most known SMGs are the serial robots named SCARA. Pick-and-place tasks are typical industrial applications that SMGs can accomplish. In the literature, 3T1R parallel manipulators (PMs) have been also proposed as SMGs.

In this study, a decoupled controller, consisting of a force controller and a torque controller, is designed to achieve a smooth translational and rotational motion control of a group of nonholonomic mobile robots. The proposed controller also solves the problem of obstacle avoidance, where obstacles with arbitrary boundary shapes are taken into account. Since the tangential direction of obstacle boundary is adopted as the guiding direction of a robot, the proposed controller allows a mobile robot to escape from a concave obstacle, while the robot could be trapped with most of the conventional
