        abstract = {In today’s fast-paced world, the idea of turning your regular home into a smart home is no longer a luxury, it’s a practical way to save time, energy, and effort. This project focuses on building a simple and low-cost home automation system using an Arduino UNO and Bluetooth technology, allowing users to control appliances like lights and fans directly from their smartphones.
The system works with the Arduino UNO acting as the brain, connected to an HC-05 Bluetooth module that receives commands from a mobile app. When a user sends a command from their phone, Arduino processes it and activates the desired appliance through relay modules. Two 4-channel relay boards are used—one handles turning on/off appliances like two lights and a fan, while the other connects to a standard fan regulator. This clever setup lets users control fan speed wirelessly, by switching different resistance levels just like a manual dial. To make the system more interactive and smarter, a DHT11 sensor is added to measure room temperature. The readings are shown on a 16x2 LCD screen, so users can always check the current temperature. For safety, an MQ2 smoke sensor is included; if smoke is detected, a buzzer sounds immediately to alert everyone. Another smart feature is the use of a PIR motion sensor. If no movement is detected in the room, the system automatically switches off all appliances to avoid wasting energy—a simple step that helps save electricity. This project shows how everyday living can be improved with basic electronics. With easy-to-find components and simple coding, it’s a great step toward building an affordable, efficient, and safer smart home. The popular concept of a home automation is of a machine that looks and works like a human being. The industry is moving from current state of automation to Robotization, to increase productivity and to deliver uniform quality. The industrial robots of today may not look the least bit like a human being although all the research is directed to provide more and more anthropomorphic and humanlike features and super-human capabilities in these. One type of robot commonly used in industry is a robotic manipulator or simply a robotic arm. It is an open or closed kinematic chain of rigid links interconnected by movable joints. In some configurations, links can be considered to correspond to human anatomy as waist, upper arm and forearm with joint at shoulder and elbow. At end of arm a wrist joint connects an end effect which may be a tool and its fixture or a gripper or any other device to work.},
