The navigation system of mobile robot should have the capability of environment cognition, action decision, motion control, and state monitoring. This paper presents a design of mobile robotcontrol architecture and a survey about the navigation control method. In vision based mapping domain, our research put emphasis on the hybrid of model and appearance based approach. An environmental model of mobile robots is built with an improved Voronoi Diagram method. This method embodies the network structure of the environment-free area with fewer nodes, so the complexity of path planning is reduced largely. Hybrid navigation strategy composed of deliberative planning and local optimization in unknown environment is studied. An improved D* algorithm for deliberative planning in complex situation is proposed for avoiding local minima trap through searching a path from leave point. The reverse D* algorithm can decrease the calculation largely compared with the traditional D* algorithm in unknown environment.

The article focuses on the research. Development and prototyping of the "Intelligent Modular Service Mobile robotcontrollable via Internet" using open-source meta-operating system/platform ROS. The robot can be controlled either locally via an immediate console or remotely (via Internet) using a remote terminal. The immediate control is implemented by means of a computer terminal. The remote connection can be made over any TCP/IP enabled network such as the Internet. Software architecture of the remotely controlled robot consists of two major parts - ROS part and remote interface. The Remote control consists of two parts - Server and Client. The Client accepts user input and transmits the corresponding commands remotely to the Server via TCP/IP connection over a network (i.e. the Internet). The Server listens for Client connections and accepts commands from the connected Client. Such kind of mobile service robots can be used for servicing of elderly and/or disabled people, in a semiautonomous of fully autonomous mode of control from a distance via Internet As they are a great number of such applications it increases the social stability of the society.

This paper presents a novel method to control a robot arm based on the human skeletal information. First, the depth data is obtained by using a Kinect device. Skeletal tracking technology is used to deal with the depth data to match the various parts of the body and the 3D coordinates of each joint of the body are established. Then, the 3D coordinates are proposed to calculate the rotation angle of the human waist, shoulder, elbow and wrist joints. These four joints of the body are one-to-one correspondence with the four joints of 4-DOF robot arm. Finally, a transformation is conducted to map the calculation results into control commands, and the control commands are sent to the controller of robot arm by serial ports to achieve body feeling interaction. The experimental results show that the method can effectively control the robot arm to rotate and grab objects.

This paper describes a speech pre-processing and feature extraction methods and described the principle of generalized regression neural network (GRNN). In order to use neural networks for speech recognition, this article uses the variable frame-shift average frame method to average the characteristic parameters of the collected voice frame, and the feasibility of the variable frame-shift average frame method in neural network input parameters normalization is verified by experiments. In this paper, according to this method, the speech recognition based on the generalized regression neural network (GRNN) successfully ported to an embedded system, and realized the pipe climbing robot's real-time speech control.

Traditional developments of intelligent terminal system could control only one robot and most were based on WinCE platform, which have poor versatility and expansibility. The robot hand intelligent terminal system proposed by this paper was an embedded equipment based on AT91 series chip. It had good human-machine interface with Linux system and Qt4 as software support. It adopted touch-screen technology and (IC)-C-2 keyboard as input device. It had two kinds of programming method, manual teaching-programming and off-line programming. The test shows that its volume is small and its weight is light to easy to operate robot handily.

Swarm robotics deals with the multi-robot coordination for achieving the common objective. The latest research in this field focuses on more complicated domain of problem where swarms of robots may require to physically dock together to achieve the goal. The physical docking may be required to move over a big obstacle or also to perform precise physical connection with certain objective e.g. battery charging. In this research, the information from vision sensor is considered to provide support for performing precise physical docking. The robotic system considered in this study requires the robots to autonomously recharge their batteries for guaranteeing long term operations and also to perform complicated physical docking for which precision is necessary. A very simple but effective solution based on LEDs, used in a specified pattern on docking station, is adopted. The approach presented in this research is found computationally less expensive so is suited to be used with swarm robotic system which uses small robots with limited memory and processing resources.

In this paper, controlling the motion of mass center of robot by different motion laws is discussed to reduce motor's drive power of robot joint. Firstly, correlation theory is described;obtain that if the (AV) value of motion parameter of robot' mass center is smaller;the torque of drive motor which needs to drive robot is smaller under the same conditions. Then, in the process of robot ZQROT-I running the straight gait, two typical motion laws are used to control mass motion of robot;motion performance of the robot is analyzed with Adams. Analysis result indicates that control mass motion of robot by the use of motion laws with small (AV) value has certain effect in saving working energy of robot.

Due to the function expansion of the robot with hand-foot-integration, the robot's frame which is a original common motion platform turns to a mechanical grab platform with floating. The workspace calculation of the robot's working arm is the prerequisite for the robot starting to grab the aim. In this paper, the calculation system of the robot's workspace on fixed pose is introduced. The calculation of the robot's total centroid position is described, the stability of the robot is analyzed and the relationship between the workspace of robot and the stability criterion is discussed. The calculation process of the workspace is given and a numerical example is illustrated. The System can be used for motion control of robot and provide the theory basis for realization of automatic grab.

Visual servo control is one of the central issues in the research field of intelligent robot. In order to obtain more effective information from the environment, visual sensor is used in robotcontrol. This paper mainly studies the application of intelligent algorithm in visual controller. Through the simulation comparison between Single neuron PID and Fuzzy adaptive PID which are introduced to IBVS, we can find that the proposed method could get better effect in convergence and fast performance.
