This paper demonstrates three-dimensional modeling method of virtual reality, and presents a 3D interactive virtual scene design based on the Unity 3D technology, combined with AutoCAD, MultiGen Creator and Unity 3D software platform. In this process, the scene and different format file has been optimized, the network interactive viewing of virtual scene is realized too. It focuses on an example designed to obtain a better real-time, interactive and good visual effects.
According to the characteristics of fixture, a method is introduced to develop a modular fixture parts library by using visual programming language VC + +, SolidWorks API interface and configuration technology. First of all, the modular fixture Library has been established through the configuration technology of driving parameters. Secondly, it is programmed to generate a pop-up menu and SolidWorks plug-ins to achieve the module fixture parts call. At the same time, management and utilization of the modular fixture Library is completed, providing users with rapid fixture design based on 3D modeling environment, and contributing to the promotion and application of CAD technology in the machine tool industry
Educational robot is a platform of new educational technology. Student could study new knowledge in execution, and discover new things in exploration. It can enhance the ability of analyzing and solving problems. Orchestic robotic vehicle is designed to give the arrangement and innovation in educational robot platform. With the sensor, dance movements of each vehicle can run according to the route and coordinated motion. There is a major hardware platform which is Arduino, with ATmega328 chip of AVR microcontroller. A QTI line sensor and SHARP-GP2D12 infrared distance sensor are used in the design. Xbee wireless communication module is based on ZigBee technology which is low power network protocol of EEE802.15.4 standard. By researching and comparing several methods of control, this paper analyzes characteristics of them and the advantage and potential of development of synthetic control are testified. Choreography and coordinated control is realized for the dancing wheeled mobile robot scheme.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
