Powered wheelchair is a mobility commonly used for people with disabilities. Recently, to improve the safety and efficiency of powered wheelchairs, various systems with control assistance are proposed. However most of the systems suppose joystick as input device and doesn't consider about people with difficulties using it. Not all devices alternative to joystick have enough operability compared to joystick. In this paper, considering corridor passing as verification environment, an action control method to drive through the corridor safely and efficiently for wheelchairs controlled by devices with low operability is presented. To achieve safe and efficient driving, proposed method considers the time series of passenger's input commands and combines the environmental information to select effective direction and speed for the wheelchair instead of passenger. Moreover for environment recognition, corridor detection algorithm is also proposed. To verify the effectiveness of proposed method, simulations and experiments were carried out.

In this paper, a method for on-line fault detection and isolation (FDI) of bond graph (BG) modelled uncertain parameters systems is proposed. In this case, we don't have to calculate the Analytical Redundancy Relations (RRAs) since residuals are directly generated from the Diagnostic Bond Graph (DBG). Detection is based on fuzzy logic approach. For isolation, two methods exploiting the causal properties of the BG model are used: Fault Signature Matrix (FSM), and exoneration. A real simulation example is provided to show the efficiency of the proposed methods.

Electro-hydraulic shaking table(EHST) is a useful experimental apparatus to real-time replicate the desired acceleration vibration signal for evaluating the performance of the tested specimen structural systems. A three axis six degree-of-freedom(DOF) EHST system with eight hydraulic actuators is presented in the paper. A decouple control method is employed to lower the acceleration couple among the six DOF. The procedure of the decouple controller is programmed in MATLAB/Simulink, and then compiled to a realtime PC with Microsoft Visual *** for implementation. The experimental results demonstrate that a better tracking performance with the improved servo controller is achieved in experiments by using actual EHST.

This research concerns the acquisition of 3-dimensional data from images for the purpose of modeling a person's head. This paper proposes an approach for acquiring the 3-dimensional reconstruction using a multiple stereo camera vision platform and a combination of passive and active lighting techniques. The proposed one-shot active lighting method projects a single, binary dot pattern, hence ensuring the suitability of the method to reconstruct dynamic scenes. Contrary to the conventional spatial neighborhood coding techniques, this approach matches corresponding spots between image pairs by exploiting solely the redundant data available in the multiple camera images. This produces an initial, sparse reconstruction, which is then used to guide a passive lighting technique to obtain a dense 3-dimensional representation of the object of interest. The results obtained reveal the robustness of the projected pattern and the spot matching algorithm, and a decrease in the number of false matches in the 3-dimensional dense reconstructions, particularly in smooth and textureless regions on the human face.

We consider at this paper the complicated task when the robot manipulator is controlled remotely via the World Wide Web and has to catch the moving object. The robot working environment is non-structured and dynamic. Neither classical teleoperation nor pure robot programming could solve the task of grasping the moving object in such a case. We used the shared autonomy approach to implement the capture task. The operator plans the capture at high level, and the capture is implemented by the robot using vision system. Human-Robot Interface is based on HP webOS Open Mobile Platform using HP Pre or HP TouchPad (tablet computer) as the operator consoles. Using the touch-based control interface and real-time 3D models of the remote robot and working environment make the grasping operation effective, reliable and simple.
