A biomimetic underwater vehicle propelled by two undulating long-fins is introduced in this paper. The concerned vehicle is propelled by two symmetrical undulating long-fins installed on both sides. Ten servo motors are employed to drive the long-fins and cosine wave function is employed for motor control. A real-time control system is designed for controlling the long-fins by adjusting its oscillating frequency and oscillating amplitude. An inertial measurement unit is installed to collect the accelerations and angular velocity. To obtain the relationship between oscillating frequency/amplitude and swimming performance, kinematic analysis and hydromechanic analysis are given. By dividing the long-fin into many small elements and computing the hydrodynamic force acting on each element, the instantaneous thrust generated by the long-fin is obtained. Then the average thrust of the long-fin is obtained by summing up the forces acted on the elements in one undulating period. Then swimming experiments are carried out to validate the vehicle design and kinematic analysis and hydromechanic analysis. And two swimming motion modes including marching and rotating locomotion are chosen. Finally, discussions between the swimming performance and the oscillating parameters are given.
This paper presents a novel image denoising framework using overcomplete topographic model. To adapt to the statistics of natural images, we impose sparseness constraints on the denoising model. Based on the overcompl...

The paper describes our preliminary investigation of haptic interaction between the human and virtual iCub robot. With haptic interaction,the user is able to have tactile sensensaiton of the robot environment,and hence to manipulate a robot remotely,for instance,from the user's office to perform some tasks at home,or a patient operation,realized by a surgeon several miles *** this work,haptic interaction has been implemented using a 3D joystick,Novint Falcon,to connect with a virtual robot created by the Cub Simulator,which works with YARP interface and simulates the real iCub robot developed by Italian *** this end,two approaches based on CHAI3D and MATLAB are introduced and implemented in this paper and furthermore,some ideas to improve the human-robot interaction performance have also been discussed.
