Water fountains have been used for thousands of years for utilitarian and aesthetic purposes. Fountain design provides an excellent opportunity for multidisciplinary projects for engineering and art students. In this paper, a falling water system is designed for an indoor fountain with a special effect feature. This system produces letters of the alphabet, simple shapes, and symbols with water jets. A microcontroller is used and programmed to create and sequence through interesting arrangements of water displays. This paper offers the hardware and software parts of light fountain control system that adjusts the water heads. The fountain hardware system consists of Arduino MEGA 2560, relays, water valves, power supply to operate the electrical circuit, in addition to the iron structure of the presentation of the shapes. The software part consists of the visual basic language written in a PC device and C-Language written on Arduino device to control the falling water system. The experimental results are tested for different alphabetic words and graphical shapes.

In this paper, a new technique for multi-robot localization in an unknown environment, called the leader-follower localization algorithm is presented. The framework utilized here is one robot that goes about as a leader and different robots are considered as followers distributed randomly in the environment. Every robot equipped with RP lidar sensors to scan the environment and gather information about every robot. This information utilized by the leader to distinguish and confine every robot in the environment. The issue of not noticeable robots is solved by contrasting their distances with the leader. Moreover, the equivalent distance robot issue is unraveled by utilizing the permutation algorithm. Several simulation scenarios with different positions and orientations are implemented on (3-7) robots to show the performance of the introduced technique.
