Research on Picking Manipulator Virtual Design and Simulation System

In the development of product virtual design and simulation system, in order to achieve the cooperativity, identity and reusability of intelligent design, virtual design and enterprise product design, the unified standard and standard definition about solid modeling properties were necessary. First, the virtual product naming standards used for modeling and simulation as a reference for the virtual mechanical product design were firstly proposed. Second, the structure of the fruit picking manipulator virtual design and simulation system was constructed, and a manipulator mechanism design module was developed, including the parametric design and knowledge reuse. Third, the knowledge base and 3-D simulation module were constructed. Fourth, through the known 3-D coordinates of objects obtained by manipulator visual, the inverse about manipulator movement and algorithm were realized by software, and the 3-D simulation about the object positioning and picking was realized in virtual environment. Fifth, the fruit picking manipulator virtual design and simulation system was developed. Finally, 3-D simulation and experimental prototype were used to validate the critical technologies.
