  Many researchers have studied robot system identification in recent years. Nonlinear system identification, whether, it be forward or inverse model identification, is becoming increasingly important in modern control applications. Nonlinear system identification can improve control performance significantly, especially when the system dynamic behaviors are unknown and exhibit great nonlinearity. Additionally, the network has been applied to control engineering. The concept of network simulates the concentration of a set of antibodies. The network system has the following features: self-organization, memory, recognition, adaptability and the ability of learning. Therefore, the network could be applied to nonlinear system identification and provide various feasible options for system models with robust and adaptive characteristics.

  The purpose of the research is to improve the development of the omnidirectional images by using the single beam projector, which is combined with the low cost and reasonable hardware and software. We project the 360-degree images to the cylindrical screen in space through the omnidirectional projecting system and make a Tele-present immediately. The operators will be able to see the 360-degree omnidirectional images, which are just like in the actual situation. In this research, we develop the low cost omnidirectional projecting system by combining the self-made conical mirror with the general projector. It makes the operator’s view be wider and replaces the conventional projector to improve the fault of that the view angel is not enough and the images are discontinuous. Moreover, the omnidirectional projecting system not only saves space but also improves the fault of traditional monitor system, which causes to waste spaces due to its need of using more projectors and closed-circuit televisions when monitoring the same space. Otherwise, it would not make the operator feel dizzy by using omnidirectional projecting system to replace the Eye-Trek. The omnidirectional projecting system is combined with the haptic interactive motion simulator to form the reality system of the Tele-present system, making the operators feel immersive.

  This study presents a real time effective human emulation vision tracking system, which is built up by two webcams and can detect objects in a 3-D space. Because of our programming in this software program, it becomes suitable for teaching and research. In this paper, we set up two webcams by an optical parallel method and deliver images to PC by a USB (universal serial bus) interface. The computer carrying out the image processing using an effective tracking rule to monitor and fast lock the object. Besides, this close-loop system contains two servo motors that control the webcams platform to pitch and yaw target centered in the monitoring image. It can measure the depth of the objects from two webcams by trigonometric function relationship. Finally, we make a virtual environment to verify the capability of this tracking system.

  In this study, an interactive virtual reality motion simulator is designed and analyzed. The main components of the system include a bilateral control interface, networking, a virtual environment and a motion simulator. Virtual reality entertainment system uses a virtual environment that enables the operator feel the actual feedback and distorted by human motion sensing device, from the virtual environment, as he/she will be in the real environment. The control scheme for the simulator uses the change in velocity and acceleration that the operator imposes on the joystick, the environmental changes imposed on the motion simulator and the sensor device feedback to the operator to maneuver the simulator in the real environment. In addition, we develop a calculating method to evaluate the ratio of the simulation results. It is shown that the proposed control scheme can improve the performance of the visual entertainment system. Experiments are conducted on the virtual reality entertainment system to validate the theoretical developments.
