The proposed Remote SCADA System (RSS) is a smarter, faster and more reliable way to control high power machines and monitor their sensors, data, and failures. The proposed system focuses mainly on building our own complete SCADA software and not using open-source SCADA software. The proposed RSS can use unlimited number of added Remote Terminal Units (RTU) nodes and each of them can handling unlimited number of input/output and can be used under different operating systems like Windows and Android. Using RSS all machines can be monitored and controlled by a single click from anywhere at any time. By doing this a real-time response from RSS system can be achieved. It’s mainly based on standard communication techniques between remote nodes and single server-side application that talk to each node with its own ID and modify its instant database. So that every time accessing this web application, a real-time access to these nodes data and a virtual control room controls each General Purpose Input/Output (GPIO) in the selected node can be gotten. When a new event is happened in server-side program, it will be broadcasted to all related. On RSS there are two main points to deal with, the request latency and security of the system. This paper studied how the system latency and security are improved to obtain the needed values. The proposed RSS is a very secure program which have 4 security levels; authentication, authorization, RSA and CBC encryption system. Also, the encryption algorithms used in RSS are RSA and CBC block cipher encryption system. It is mixed way to prevent any attacker from breaking the cipher. First of all, RSA generates the public and private keys, and then CBC generates its Initialization vector and a random encryption key. Then a special function sends all of these keys encrypted with a pre-stored token in the data base and node memory which varied from node to another. Finally, node generates its private key from loaded public key. With this combination the speed of symmetric encryption system and the security of asymmetric encryption system can be achieved. On the other hand, the level of security firewalls needed to be Brocken by the attacker to brock the cipher is increased. The proposed system achieved low cost comparing with reported work; it is lower than Arduino + WIFI method by five times and 13 times lower than Raspberry-PI method. The proposed system is applied in educational systems, where it is used for teaching unlimited number of students Online.

Pipelines have widely spread applications in the industry. Water, sewage, flammable liquid, high-pressure gasses, and oil are transported using pipelines. These pipelines are long, interconnected, and may be constructed underground or underwater. This makes their monitoring, periodic maintenance, and repair a hard job when done by human operators. Hence, a robot system capable of carrying out these complicated operations in pipelines is extremely requested. In this paper, a mechanical design and a prototype of an in-pipe robot system for cleaning 0.5 m inner diameter water pipes are presented. The proposed robot system is designed to perform cleaning operations for straight and curved horizontal water pipes based on the abrasion concept. The in-pipe robot system has three modules; forward and backward motion module, two identical cleaning modules that can move in rotational motion, and radial motion (in and out). These three modules are designed to have the robot's two main positions: an open position (for cleaning) and a closed position (while entering and getting out of the pipe). A 3D model has been built using SolidWorks software, then a finite element analysis was carried out on a robot's frame using two materials: Steel and Aluminum. However, the Steel material has been selected due to its high rigidity. The robot control system was done using Arduino software. Robot dynamics were simulated in a Simulink environment. The real-time robot testing showed that the proposed robot mechanism can complete the cleaning operations effectively. The developed robot is expected to minimize maintenance time, effort, and cost.
