This paper studies the design of hardware system and implementation of program algorithm for emotion robot, then focuses on the specific of wireless communication subsystem and related key technique.
In component-based robot software, it is crucial to monitor software faults and deal with them on time before they lead to critical failures. The main causes of software failures include limited resources, component-interoperation mismatches, and internal errors of components. Message-sniffing is one of the popular methods to monitor black-box components and handle these types of faults during runtime...
A* algorithm was a heuristic state space search method under the known environment originally. In this paper, the A* algorithm is improved and optimized by introducing a variable of visits number so that it can work in unknown environment. Besides, the path planning process is simulated by the improved A* algorithm realized in the Visual C ++ 6.0 development environment. The feasibility and effectiveness...
Total Knee/Hip Replacement(TKR/THR) is one of the most important orthopedic surgical techniques of this century. If patient's whole joint is damaged, an artificial joint (total hip/knee replacement surgery) can relieve patient's pain and help the patient get back normal activities. The goal for TKR/THR is to relieve the pain in the joint caused by the damage done to the cartilage. The surgeon will...
Telesurgical robot systems (TRS) are often deployed in unattended environments such as battlefields or rural areas. Therefore, adversaries can easily access the devices, compromise the system, and install their own malware. If the integrity and health of the system software and configuration files are not verified before their usage, the safety and lives of the injured soldiers and patients may be...
In this paper we present the synchronization and driver architecture of the DLR LWR-III, which supplies an easy to use interface for applications. For our purpose we abstracted the robot hardware entirely from the control algorithms using the common device driver concept of modern operating systems. The software architecture is split into two modular parts. On the one side, there are device drivers...
One of the major costs and inhibitors to practical robotics research is the time required for the creation of the embedded systems that implement the discrete event control in experimental robot systems. Using a standardized system architecture can reduce this time, but is often not feasible due to the rapidly varying requirements present in robotics research, and the considerable cost associated...
The following topics are dealt with: neural networks; fuzzy systems; evolutionary computation; adaptive dynamic programming and reinforcement learning; computational finance and economics; data mining; computer games; virtual reality; intelligent systems; robotics and cybernetics engineering; operations research; signal processing; human factors, and social issues; parallel and distributed architectures;...
In order for robots to be socially accepted and generate empathy it is necessary that they display rich emotions. For robots such as Nao, body language is the best medium available given their inability to convey facial expressions. Displaying emotional body language that can be interpreted whilst interacting with the robot should significantly improve its sociability. This research investigates the...
Bicycle robots are such a kind of mobile robots subjected to nonholonomic constraints and under-actuated degree of freedom (DOF) simultaneously, and it is a common scenario for these robots to climb a slope. The research in this paper is focused on dynamic modeling and dynamic characteristics analysis of a front-wheel drive bicycle robot under the state of slope-climbing. The concepts of critical...
Robot drivers are used in motor testing and research institutions. They can be used in determining velocity and they can keep velocity fixed in a specific cycle. This command is done by man or motor cycle software programs present research is focused on control system of throttle pedal, which is known as cruise control system. In present system the Operator gives the command of velocity to the first...
Robot skills can be taught and recognized by a Programming-by-Demonstration technique where first a human operator demonstrates a set of reference skills. The operator's motions are then recorded by a data-capturing system and modeled via fuzzy clustering and a Takagi-Sugeno modeling technique. The resulting skill models use the time as input and the operator's actions as outputs. During the recognition...
In order to solve the problem of impact in robotic force position control during the initial state, the hyperbolic tangent filter function which was constituted a non-linear PID was used to process tracking error and speed. A robot force and position controller without impact was achieved. The Popov method was applied to prove the stability of the system. Based on the force and position control experiment...
Virtual robotic environments are commonly used to develop, prototype and simulate control strategies and algorithms for single or multi-robot systems. Once developed, the control strategies and algorithms can then be implemented on physical systems. However, the transition from virtual to physical systems can be rather tedious due to different programming languages, application programming interfaces,...

The purposes of SMDM-MC are to support the manufacturing engineering processes based on the simulation model and to extend the range of control applications and simulation applications using the PC based control. SMDM-MC provides the simulation model which controls and monitors the manufacturing...
Path finding is importance for various areas such as robotic, game and transportation. It has a significant effect to the prosperity of economic increasingly. This research proposes three essential improvements. First, the position of each agent (player or robot) will be transferred to multilayer scene using Perspective Projection Method (PPM). It is able to send begin position and destination position...
A feasibility study has been established to integrate agent and auto-ID technologies in manufacturing control applications. A multi-agent system (MAS) framework for intelligent manufacturing has been established. The intelligent MAS environment attempts to exploit the potential of Auto-ID (RFID in particular) technology in manufacturing applications. The aim is to evaluate the applications of Auto-ID,...
Until now, high-performance has been the main objective in software for robotics and, as a result, the ad-hoc implementations have been optimized for specific hardware and platforms. Nevertheless, there is a renewed interest in designing robot control architectures to be reusable and maintainable as possible, so that existing software modules can be adapted to new platforms and requirements, thus...
In this paper, a cable-driven spherical joint with angle feedback is proposed and the geometric numerical inverse kinematic algorithm is analyzed. Based on this, a new online control method is presented. In this method, the actual position of the spherical joint is calculated via inverse kinematics and the control error is compensated immediately. A experimental system with industrial PC (IPC) and...
