The participation of robots in building construction is already a global trend. Compared with the actual construction with a large number of manual participation at this stage, the stability of the robot construction process will greatly affect construction efficiency and construction accuracy. As a future material carrier for building industrialization, robot construction has promoted the realization process of customized production and intelligent on-site construction. How to coordinate the robot platform, tool end development, building materials, construction tasks and on-site environment for the complex on-site construction environment and mass production needs The relationship between the optimization of robot construction technology will become an important step in the future development of building industrialization. This paper focuses on the actual case, through the simulation of a built-in residential reconstruction, from the design process, the actual construction process to the final result, exploring the possibility of robots participating in the construction of residential buildings. It is hoped that the construction performance of the on-site construction will be improved through the participation of robots.
