this paper presents the scheme of a physiotherapy service robot including the mechanical architecture, control system, visual position system, etc. the robot can treat degenerative disease and chronic disease of middle-aged and aged people by Chinese massage skill, the main body of which includes a massage adjustable bed, two 4-DOF robot arms and two massage hands that can accomplish various massage manipulations. Two arms cooperate to improve the massage efficiency, and provide sufficient strength and enough reachable workspace for massage. the manipulators are controlled by a TRIO multi-axes motion controller and a embedded computer module. Physiological signal and massage pressure is detecting in real time in massage process to ensure a scientific and safe therapy. vision System sends the recognized acupoint position to the master system to track the patient's body, and the acupoint being massaged is displayed in real time by the 3D virtual display model. the robot can execute ten massage manipulations, which make traditional Chinese massage can have a robot instead. the effectiveness for degenerative lumbago in middle-aged and aged is demonstrated by laboratory examination and clinical trial.

this paper describes a method of human guidance for autonomous cruise of indoor robot. A low-cost robot follows a person in a room and notes the path for autonomous cruise using its monocular vision. A method of video-based object detection and tracking is taken to detect the target by the video received from the robot's camera. the validity of the human guidance method is proved by the experiment.

3D vision location is one of the most famous researches in computer stereo vision area. However, the traditional algorithm is not only complicated but low-matched. We proposed a new algorithm in this article: First of all, we use Zhang Zhengyou camera calibration methods for vision calibration. Secondly, Epipolar constraint, NCC similarity measure and disparity gradient compatibility are individually used in different stages of sparse feature based stereo matching. the last, least squares space coplanar approximation is used to obtain the 3D coordinates of matching points. It has been proved not only operated easily but provided with high stability and robustness.

Image processing algorithms and fuzzy logic method are used to design a visual tracking controller for mobile robot navigation. In this paper, a wheeled mobile robot is equipped with a camera for detecting its task space. the grabbed environmental images are treated using image recognition processing to obtain target's size and position. the images are treated using input membership functions as the fuzzy logic controller input. the recognized target's size and position are input into a fuzzy logic controller in which fuzzy rules are used for inference. the inference results are output to the defuzzifier to obtain a physical control signal to control the mobile robot's movement. the velocity and direction of the mobile robot are the output of fuzzy logic controller. the differences in velocities for two wheels are used to control the robot's movement directions. the fuzzy logic controller outputs the control commands to drive the mobile robot to reach a position 50cm front of the target location. the simulation results verify that the proposed FLC is effective in navigating the mobile robot to track a moving target.

the objective of this article is reporting the participation of the SIMD-IDIAP group in the robotvision@ImageCLEF 2012 challenge. this challenge addresses the problem of multimodal place classification, and the 2012 edition has been organized by the members of the SIMDIDIAP team. One of the main novelties in the 2012 edition of the task has been the proposal of several techniques for features extraction and cue integration. this paper details how to use all these techniques for developing a multimodal place classifier and describes the results obtained with it. Our approach ranked 7th for task 1 and 4th for task 2. the complete results for all the participants of the 2012 robotvision task are also reported in this article.
