Flexible load transfer robot system based on intelligent construction site BIM system

The invention discloses a flexible load carrying robot system based on an intelligent construction site BIM system. The robot system comprises a construction site modeling module, an environment map self-building module, an article packaging and transporting module and a flexible load carrying module. The construction site modeling module is used for modeling according to a drawing of a construction site building; the environment map self-building module is used for performing optimal path planning on the path of the transfer robot according to articles required by each construction site on the basis of a modeling result; the article packaging and transporting module is used for packaging and placing the required articles based on the articles required by each construction site and the optimal path plan; and the flexible load carrying module is used for transporting the required articles to different floors and different buildings according to the optimal path planning, so that three-dimensional flexible oper
