The unmanned automatic vehicles (UAV) are important elements in industrial application, such as unmanned carriers in warehouse. With the great progress in the intelligent transportation systems, the UAVs are often applied to drive automatically. The mechanical vision replaces the human's eyes to be the feedback component. By the image processing, the necessary information can be figured out. However, due to the complicate calculation of image process, it will take a long calculation time from fetching image to making image information. Hence, a novel control rule that is the Grey-Fuzzy-Fuzzy controller is proposed in this paper for vision guided control of UAVs. The novel rule consists of the base-layer and upper-layer fuzzy controllers. The base-layer fuzzy controller is the classical fuzzy controller using the position error and the error difference to be the input variables. The Grey prediction is used to estimate the position error at the time of making image information. Then, the upper-layer fuzzy controller uses the two input variables, which are the estimated position error and the estimated error difference, to correct the base-layer fuzzy controller's output signal. Finally, an experimental UAV is developed to examine the potential of the proposed control scheme. The vision-based experiment of automatically driving of lane-following is carried out in this paper. The experimental results show the proposed controller will eliminate the swinging phenomenon and increase the accuracy while tracking. The experimental results also show the practical capability of the Grey-Fuzzy-Fuzzy controller.

In order to provide an ideal test-bed for the research of intelligent bionic leg (IBL) controlled by magneto-rheological (MR) damper, a novel humanoid robot-biped robot with heterogeneous legs (BRHL) is proposed. First the conception and research purpose of BRHL are introduced. Then bionic design of BRHL is analyzed in detail. Coordinated dynamics model and MR damper model are given. In the end, diagonal recurrent neural network is discussed and control simulation is done. The result indicates that BRHL can simulate human's gait well and is an ideal test-bed of intelligent bionic leg.

This paper presents a free Java software platform which enables users to easily create advanced robotic applications together with image processing. This novel tool is composed of two layers: 1) Easy Java Simulations (EJS), an open-source tool which provides support for creating applications with a full 2D/3D interactive graphical interface, and 2) EjsRL, a high-level Java library specifically designed for EJS which provides a complete functional framework for modeling of arbitrary serial-link manipulators and computer vision algorithms. The combination of both components sets up a software architecture which contains a high number of functionalities in the same platform to develop complex simulations in robotics and computer vision fields.

This paper presents a complete artificial vision system development and implementation for a mobile robot recognition and obstacles detection, which integrates a statistical segmentation method with frequency filtering in order to achieve luminosity independence, exploiting the advantages of known image processing techniques by mixing them into a robotic application. The system proposed determines the mobile robot's position and orientation, using a color segmentation approach based on the Mahalanobis Distance, and the position and size of obstacles in the robot's environment using a parallel scheme based on both Sobel edge detector and Otsu's threshold. The Mahalanobis distance calculus was implemented using a real-time FPGA architecture, in order to detect t he robot's position. Tests in the real robot's environment are presented obtaining results that are independent from the background characteristics and strongly robust on the luminosity variability.

Recent research in orthopedic surgeries indicates that computer-assisted robotic systems have shown that robots can improve the precision and accuracy of the surgery which in turn leads to better long-term outcomes. An orthopedic robotic system called OrthoRoby and an intelligent control architecture that will be used in bone cutting operations are developed. A medical user interface (MUI) is developed and integrated into the OrthoRoby system. MUI is used by the surgeons to import images of the patients' bone as inputs and outputs a bone cutting trajectory. A series of experimental tests were conducted to evaluate the performance of the MUI.
