Using multiple robots to form artificial swarms and using methods of self-organization to carry out collective cooperation to fulfill complex tasks are hotspots in researches of robotic control. Artificial swarms with the advantages of distribution, flexibility, robustness, autonomy and so on, will be the main approach to accomplish the complex tasks, such as distributed wireless network, distributed...
Realizing robots' controlling in controlling way of saving dof has a broad prospect and applied space using control technology. The paper discussed controlling horses using reins as inspiration, realizing the operation of mobile equipment of reins' control. The experiment confirmed the feasibility of operation by the first stage; Comparing the operating system of reins with the operating system of...
A problem in configuring modular self-reconfigurable robots with distributed control is determining whether a module can be moved without breaking the system apart. In finding a set of modules that can be safely moved, the key issues are to maximize the number of mobile modules identified and minimize the time consumed in finding these modules. In this study, a distributed search algorithm is proposed...
Topics include a new Chinese supercomputer that ranks as the world's most powerful, research into using millimeter-wave frequencies to enable 5G wireless communications, security experts finding the first ransomware that affects mobile devices, Google beginning work on a project to provide broad Internet access via a network of high-altitude balloons, an innovative robotic jellyfish that could serve...
In this paper, we built a behavior model for the Ubiquitous Display (UD) to provide a situation oriented service to the users in a large-scale public facility. The UD is a mobile-projection robot to support the user with visual information. If the UD provides a service in a public facility, we should assume the possible situations previously. According to the situation, the model should be built in...
In this paper we introduce a new application of potential field concept that is used for resource management in distributed environments. More precisely, we propose an efficient algorithm to assist the medial staff in a hospital to deal with a crisis caused by receiving a large number of patients simultaneously. Our algorithm runs by all member of the medical team in parallel and guides every team...
W-Climbot is an inchworm-like biped wall-climbing robot we developed with a modular approach. Consisting of five joint modules and two suction modules, the robot is actually a mobile 5-DoF arm with dual end-effectors at the two ends. With this kinematic structure and biped climbing mode, W-Climbot has superior wall-climbing function (e.g., great ability to omni-directional locomotion, to negotiate...
This paper mainly discusses the poles' effect on the performance of a two-wheeled balancing mobile, which is inherently unstable and so needs to be stabilized in a large angel range by a balance control unit. Three aspects are included: first, similarity between the linearization model and the original nonlinear system model is increased by using feedback linearization; Second, system transient performance,...
A continuous guidance law based on finite-time control theory is presented for the plane model between the missile and the target. The proposed guidance law includes the line-of-sight (LOS) angular rate and a desired LOS angular. The LOS angular rate can converge to zero in finite time to guarantee the zero miss-distance between the missile and the target; the LOS angular reaches the desired value...
In this case study, we examine the functional utility of an embodied agent as an interactive medium in stroke rehab. A set of physical rehab exercises is conducted through the direct engagement of an embodied agent, the uBot-5. Based on the preliminary data, we argue that a general-purpose embodied agent has a potential to functionally complement human therapists in providing rehab to stroke patients.
In this paper, an improved self organizing map (SOM)-based approach is proposed for multi-robot systems to tackle the task assignment problem which focuses on the self-organization issue with a large number of robots and a large number of task locations in dynamic environments subject to uncertainties. It is capable of dynamically controlling a group of mobile robots to achieve different task locations...

This paper reports on the experience of the 2008 international summer school on mechatronics, jointly organized by the University of M'alaga (Spain) and the Technical University of Dresden (Germany). An important part of the hands-on practice and two student competitions have been based on the LEGO Mindstorms NXT Set. To stimulate lab work with representative general purpose software tools, LabVIEW...
This paper offers a framework that helps in characterizing, analyzing, and developing Unmanned Autonomous Systems (UAS) capabilities including autonomy, adaptability, and machine cognition. We propose a technical reference model that brings these levels of capabilities together into a three-dimensional graphical model. Based on this technical reference model, we offer a system-theoretic analysis framework...
Expected growth in use and implementation of wireless sensor networks (WSNs) in different environments and for different applications creates new security challenges. In WSNs, a malicious node may initiate incorrect path information, change the contents of data packets, and even hijack one or more genuine network nodes. As the network reliability completely depends on individual nodespsila presence...
Currently, robots are being used as teaching tools and can be found in K-12 and college classrooms. The primary appeal associated with employing robots is that they tend to capture the attention of the target audience and thereby facilitate the learning process. While there are numerous robotic kits on the market today, few can be used to teach both high-level concepts in computer science and engineering...
This paper investigates the computational complexity of planning the motion of a body B in 2-D or 3-D space, so as to avoid collision with moving obstacles of known, easily computed, trajectories. Dynamic movement problems are of fundamental importance to robotics, but their computational complexity has not previously been investigated. We provide evidence that the 3-D dynamic movement problem is...
