The project consists of several structural resources; human resource considered as one of the most important resource in fact, that the human resource represents a higher percentage of the total cost of the projects. Therefore, the labour productivity is a vital subject, which received increasing attention from researchers in the construction sector, they have been aware of the importance and impact of the human productivity. Workers in the workplace are facing many problems and factors affect in the productivity, which cause a decline in the production. This is reflected negatively in the estimate at completion of the project based on project performance against the plan. Which leads to delay in the deadline as a result an increase in total costs because there is a relationship between the projects total cost and time/cost? There is an interested in fundamental problem solving and some of these problems have to be taken into consideration during the planning phase of the project, to ensure transcend the problems of low labour productivity. In this study an expert system has been established to solve the problems of the low productivity of labor factor in the construction sector. The data has been collected via a scientific research, preparing the research design and field study. In order to determine the most problems impact on productivity than other problems the (analytic hierarchy process) AHP program was used. Moreover, to facilitate using expert system a software program language (Visual Basic) was used.

The robot is constructed as a machine that can simulate a human-made operation and perform an operation without human intervention. Robots are made by mechanical components and controlled by electronic components. Computer science also participates in the planning of robots alongside other sciences. One of the operations simulated by robots and well placed in the market for consumer and industrial households is lawn mowers that are used to clean up lawnmowers. Mimo's Lawn Mower is a fully automated robot that uses intelligent motion technology to correct the graphics of a ground grass. In a graphic correction, the lawn robot can design a graphic on a lawn surface. In this dissertation, with the aim of enhancing the functions of the Mimo Lawn Mower Robot, we decided to add facilities such as the recapture of grasslands and irrigation of the lawn surface after grass trim. So first, we will examine the MiMo lawn robot and then add new features to this robot. At the end of this thesis, we list the results of this research by adding the simulation codes used in the WeBots software, the Mimo robot, and how to collect the modified grasslands as well as the irrigation of the lawn surface.

With the advent of the new sciences, and in particular the electronic and mechanical sciences, the community's need for the teaching of these sciences has grown. Lawn robots are robots with intelligent and manual motion technologies. On the other hand, these robots have lawnmaking technology that boosts electronic science and uses intermittent and direct current systems. These lawnmowers use shear blades that are controlled by an electric motor. Lawnmaking is done graphically or continuously. In a lawn mower, there is the possibility of designing a graphic or graphic text on a lawn environment. This possibility is done by image recognition algorithms derived from computer science. Lawnmowers who continuously operate lawns always keep the blade rotational engine running and continuous lawn operation. Such machines do not have graphical design capabilities. Some lawnmowers are able to store modified grass, and these machines should consider measures to counter the gradual increase in their weight. The gradual increase of this weight is due to the storage of modified grass. In this article, we will examine the technology of lawn robots and redefine the concept by examining several models of these robots.
