| In recent years,with the rapid development of artificial intelligence technology,it has become a trend for robots to replace human workers in the construction industry.With the continuous upgrading and transformation of China’s labor industry,the proportion of young people employed in labor-intensive industries has declined.In a few years,there will be a breakdown in the workforce,especially in the construction industry.In order to realize the industrialization of construction,the state strongly supports the development and application of robots in the field of construction.For this reason,this topic will design a new type of paving robot according to the atual needs of the company.The robot lays tiles according to the laying process by mimicking manual work..At the same time,the key technologies of the robot including mechanical structure stability,tile space positioning technology and paving trajectory planning are studied.To lay a theoretical foundation for the company’s product development of paving robots.The main research contents of this paper are as follows:Firstly,according to the technical indicators and functional requirements,the overall design of the paving robot is carried out.A variety of design schemes are proposed,and through comparison,the most reasonable design scheme is selected to complete the overall design of the paving robot.The mechanical structure of the robot and the composition of the control system are designed in detail.Secondly,by using finite element analysis software,statics analysis of the support frame,the roller drive shaft,and the working limit position of the paving robot in the structure is carried out.The analysis results show that the structural strength meets the design requirements.At the same time,the vibration of the support frame in the process of paving is analyzed,so as to design the vibration frequency of the vibration source.By analyzing the stability of the mechanical structure,the structure design can be optimized and the performance of the robot can be improved.Then,according to the different state of tile paving,the tile space positioning system is designed and built,and the tile positioning algorithm in two-dimensional plane and three-dimensional space is studied.The pose state of ceramic tile in space is calculated by this algorithm and the tile laying accuracy of the robot can be improved.Next,for the tile paving robot studied in this topic,the paving path is analyzed,and the movement trajectory is planned reasonably in the Cartesian space coordinate system and the joint coordinate system according to the path requirements.The planned movement trajectory is smoother,the speed is more continuous,and the impact is reduced.Finally,the prototype of the paving robot is built,including the mechanical structure and control system.Taking the prototype as the experimental object to conduct experiments on the above research content and various functions of the paving robot,including the tile space positioning experiment,the tile adsorption experiment,and the tile paving experiment.The experimental results show that the prototype meets all functional requirements. |
