In order to meet electrical information specialty practice teaching requirements of industrial robots, automatic control, machine vision and other advanced technology, improve the independent innovation ability, entrepreneurship and practice ability of engineering students, a robot experimental system was designed and developed. Combining virtual simulation technology, internet technology with specialty requirement, a virtual experiment object was designed to expand the experimental content. In order to facilitate the management of virtual teaching resources, according to the characteristics of subject and virtual experiment teaching, a unified network management platform was established to expand the scale of sharing. A "331" virtual simulation experiment teaching management system which has three centers, three levels and the integration of construction, was explored. That system promotes the development and construction of virtual teaching resources, promotes the informatization construction of experimental teaching in college, and will open up a new path for the innovation of experimental teaching reform.
