Abstract: Spectral analysis for detecting migration heavy metals in toys is widely used in domestic and international standards. In this paper, intelligent analysis system for detection heavy metals was developed utilizing Internet of Things based on current spectral analysis instruments. And the virtual application of instrumentations such as bar code scanner, balance, digital temperature/humidity recorder, spectrum analyzer and central server could be realized by using Service Oriented Architecture (SOA). The test results from different equipments and different types of data such as sample information and environmental parameters were collected automatically. And they were transported to the central server in real time. The data processing model which met the requirements of spectral analysis was embedded in the system. In that way, the system has the features of real-time data storage, automatic report generating and so on. As a result, the data recording and processing time could be decreased dramatically. Meanwhile, the risk of manual operation could be effectively reduced with improved efficiency and data processing accuracy.

Abstract: For the pursuit of developing new field in toy industry and meeting the demands in new markets, combined with current development trend of aging population in China and associated problems, this paper promotes a new product concept: toys for elder people, to satisfy the needs of the elder’s entertainment and prevention from geriatric diseases. This paper chose ‘Intellectual and Physical Promoting’ as the theme and made a research on development and design strategy of elder people’s toys, finally it analyzed the materials for the toys design.

Abstract: This paper takes the 2D image of toys and cartoons as reference to assist the amateurs to design 3D models fast and conveniently. A contour deep tracing algorithm is proposed for acquiring the whole contour, and Ferguson interpolation curve is introduced to fit the contours. Taking the control points of Ferguson curves as reference, amateurs can easily sketch curves that fit to the image contours. Decomposing the extracted contours into several feature regions, the users can draw some enclosed component contour curves of the target toys or cartoons, and then adopt proper methods to generate the 3D mesh of components. Three modeling methods, namely local deformation, symmetric deformation, and 2D FFD deformation, are introduced for modeling the 3D surface fast. Ferguson curves are also used in 3D painting on triangular surface, and large regions enclosed by the painted colors can quickly be filled with a target color. The users select a region of the image and drag them onto 3D models, and then the details, such as eyes, nose, and artistic patterns can be easily painted.

Abstract: Modern industries use many types of robots. The biped or quadped robots are the most common robots in the robot category. However, in terms of efficiency, flexibility, and stability, the developing tripedal robots could be the best candidate. The research starts from establishing the platform of the tripedal robots. The mathematic model of the tripedal robot is generated by applying the forward kinematics and the inverse kinematics. The research then adopts the MSC Virtual Nastran simulation software to calculate the optimal values applied to the tripedal robots for verification. The major issue is about the balance of the static stability and dynamic stability. The research also tries to develop the most power-saving method and the largest moving steps. The platform of the tripedal robot will become a significant design reference for the commercialization of different industrial robots, and it will provide the design of industrial robots with more options and useful applications.
