Abstract As a new product of the development of modern science and technology,
the research and development of logistics robot has become the focus of social
attention. Robot sorting and handling is the designated project of Jiangsu University
Robot Competition. According to the requirements of the competition, this paper
designs a kind of logistics robot trolley which can identify and grab materials
according to a given path and transport them to a predetermined location. The
mechanical structure design, driving motor selection and mechanical checking
calculation of the car are mainly completed. According to the later experiments, the
results show that the… More >

Abstract In recent years, with the increasing popularity of social networks,
rumors have become more common. At present, the solution to rumors in social
networks is mainly through media censorship and manual reporting, but this
method requires a lot of manpower and material resources, and the cost is
relatively high. Therefore, research on the characteristics of rumors and automatic
identification and classification of network message text is of great significance.
This paper uses the Naive Bayes algorithm combined with Laplacian smoothing to
identify rumors in social network texts. The first is to segment the text and remove
the stop words after… More >

Abstract A visual pH indicator through purple cabbage dye is selected to test the
freshness of venison. Chitosan and cassava starch of an equal weight were used to
prepare the film-forming matrix of the indicator. The crystallization of natural
purple cabbage dyes with a weight ratio of 5%, 10%, 20% and 40% were added to
the matrix, respectively. The pH color test showed that the natural purple cabbage
lyophilized powder with a weight ratio of 40% was the best for the pH indicator,
which was used to test the freshness of venison stored at 4℃. The total bacterial
count, volatile basic… More >
