In the complex unstructured road, mobile robots' ability to resist overturning is crucial. In this paper, a tracked mobile robot with passive deformation is developed based on the request of unstructured environment to the robots' movement. The robot can improve stability and the ability to resist overturning by the deformation of passive adaptive mechanisms. A comprehensive judge was made on the...
There is an urgent need to check and salvage foreign objects for the nuclear power plant. A 4-DOF underwater manipulator served for nuclear power plant can complete the examination, salvage or other actions for the nuclear power station reactor core and foreign objects in the pool. In this paper, several researches on 4-DOF underwater manipulator served for nuclear power plant are carried out as follows:...
In this paper, an upper limb rehabilitation robot based on virtual reality is developed to improve therapeutic efficacy. With the help of the robot, the patients can reach virtual items appearing randomly with impaired limbs in a virtual environment. The kinematics of the robot is analyzed and the appearance rules are made to avoid mechanical interference between the arms. Both passive mode and active...
The efficiency and accuracy of the odor source localization by robot, which just relies on the olfaction information, the wind direction information, are lower. Human often use the vision information to search suspicious target, and reach the target, and judge it by Olfaction information further. In this paper, inspired by Human's searching and declaration strategy, the robot's odor source localization,...
Partition-and-Recur (PAR) method is a simple and useful formal method used to design and prove algorithmic programs. In this paper, we address that PAR method is really an effective formal method on solving Combinatorics problems. We formally derive Combinatorics problems by PAR method, which can not only simplify the process of algorithmic program's designing and correctness testifying, but also...

An important application of graph partitioning is data clustering using a graph model--- the pairwise similarities between all data objects form a weighted graph adjacency matrix that contains all necessary information for clustering. An effective multi-level algorithm based on AIS (artificial immune systems) for graph bipartitioning is proposed. During its coarsening phase, we adopt an improved matching...
This paper presents the un-calibrated vision servo control algorithm to track the target with mobile manipulator. Color histogram distance calculation methods and shape matching method are discussed to recognize the target .The on-line estimation algorithm for Image Jacobian matrix model is designed based on the Kalman filter. With this image Jacobian on-line estimator, the visual feedback controller...
Mobile manipulators have attracted a lot of interest recently. This paper discusses the development of mobile manipulators in recent years in the aspect of motion planning, modeling and control and coordination between mobile platform and manipulator. In this paper, quite a few problems in this field were presented and relative solving methods and results were briefly introduced. A hierarchical intelligent...
A MM (map matching) method based on credibility algorithm is proposed in this paper to improve location precision of GPS (global positioning system) for the mobile robot. It can find the exact road on which the robot moves in the electronic map quickly when the longitude and latitude of the robot is known. How to extract longitude and latitude from GPS data stream is also introduced. AT commands are...
