This paper discusses the work-in-progress of a system to control a moving robot over the WWW(World Wide Web). That is, we describes the experimental results and control methods of system over the world wide web. The remote control of the system is controlled by accessing a simple form of interface that is connected to the server. For this application, a remote operator should have a general-purpose computer with Internet connection and a WWW browser to remotely operate the line-tracer through the Internet. As a remote operator summits an input by operating html files in the server, the program written in java is operated the equipment is being connected to the serial port. By being transmitted to the line-tracer through the infra-red sensor, the remote controlled signal is operated in distance. As a tool in order to identify the system's operation of the over the web is used the line-tracer.

The primary goal of the line tracer is to accurately and quickly detect the movement up to the target position given by the sensor juhaengseon. It has been used in applications in various fields such as the current unmanned transport vehicles, laser cutting machine, autonomous mobile robots and unmanned driving is possible, and is held annually at various universities in the competition field with the possibility of great progress, depending on the application. However, there arises a large difference in running performance, depending on the hardware design and control. In this paper, improving the characteristics of the tracer line and characters to design a PID controller is to apply the point on ways of improving the properties of the system.

Comparing the past and the present in agriculture, society is losing people who work in farming, and the age of those who remain is increasing. Farmers are interested in special crops if the agricultural products' costs are low and the crops are easy to grow. If the area where a crop grows is bad, the agricultural products' quality gets worse. To overcome this situation, a new approach is being tried with crops. This research offers new technology to the young generation. This paper proposes technology that uses Internet of Things techniques to automatically sparge water and pesticide on orchards and fields using a machine instead of a person. We used the open source Arduino and sensor modules to build the automatic system. In this research, a circuit was simplified, and we constructed the proper size of the system by preventing errors in sensors, keeping distance from objects, and minimizing circuit collision. The machine drives and turns its head to sparge agricultural pesticides. The machine will minimize harmful effects caused by pesticides on humans, and will be helpful to farmers.

In this paper, it is a system that informs people who take medication periodically to facilitate the convenience of the elderly and the disabled. It is a system that measures the full weight of pills that need to be taken for a week using a weight sensor, and then determines whether or not the pills are taken by measuring the weight of the reduced pills again when the user takes them. For people with disabilities who are unable to move, it includes the function of automatically transporting medicine to the user-set location at the time of use using a line tracer based autonomous vehicle. It is also configured to inform users who have not taken the pill through an alarm that includes visual and auditory functions at a specific time to inform them of this. This work attempts to help users take their medication without forgetting by segmenting the task performance process of such a system through simulations.
