A new method to collect royal jelly is proposed according to the view of industrial robot. A three-dimensional model of royal jelly collecting robot with a monocular camera is built. Detecting the particular shapes via Fourier Descriptors and finding the corresponding target points though the image shot by the camera. The vision-based process and the 3-D simulation are performed alternately to simulate picking up queen bee larvae according to robotic forward kinematics and inverse kinematics.

Executive Mechanism

Based on the characteristics and the common massage manipulations of Chinese medical massage, a practical series mechanical arm was presented to act the manipulations with the parallel executive mechanism. Forward kinematics was solved by the Denavit-Hartenberg transformation after the kinematics model of the arm was established. And the three-dimensional model of the arm was created by Pro/E and was imported into ADAMS for the kinematics analysis. The results indicated that the common massage manipulations could be simulated by the arm correctly and flexibly, and it verified the accuracy of the mechanism design of the arm.

This paper presents a new method for the analysis of the crankshaft strength by using the softwares of solidworks, matlab and ansys. Using the powerful modeling function of solidworks, the three-dimensional model of crankshaft was established. Applying the techniques of numerical operation, graph display and GUI of matlab, the simulation calculations of kinematics, dynamics of crankshaft was carried out and the force and torque of crankshaft was obtained. Making full use of finite element analysis function of ansys, the modal analysis and strength analysis of crankshaft were made. The results show that it is valid to take the respective advantages of solidworks, matlab and ansys to establish a simple and effective approach for the analysis of the crankshaft strength, which supplies foundation for the optimization design and dynamic response of crankshaft.

Data fitting approach based on test data is commonly adopted on analyzing of thermal effect due to the thruster plume impingement on communication satellites, however, the existing methods are only available for the appendages which are regularly shaped or could be formulated. In this paper, a plume impingement analyzing approach for irregularly shaped appendages is present. The STL (Stereo Lithographic) data is firstly derived from the three-dimensional model of the appendages. Then the STL data are made a kind of interpolation to get small particle size in order to obtain a precise analyzing result. Finally, the normal vector and the location of each triangle grid are obtained from the STL data to form a new model for plume impingement analyzing on irregularly shaped appendages. The new method is proved correct by comparing with PLUME software and the method given in [4].The application range of analyzing exhaust plume impingement on communication satellites can be widely extended by the proposed method.
