Underwater robotic systems play an important role in environmental observation, water quality assessment, and exploration of submerged regions where direct human access is difficult and risky. This paper presents the design and implementation of a sensor-assisted underwater robotic framework for real-time water monitoring and exploration. The proposed system integrates an Arduino Nano controller, Bluetooth communication module, temperature sensing unit, underwater HD camera, DC motors, brushless DC motor, and electronic speed controller to enable efficient navigation and data acquisition. The robotic platform is designed using a lightweight and buoyant structure that supports stable operation on the water surface as well as at moderate depths. A mobile application provides remote control functionality and facilitates monitoring of environmental parameters. Real-time temperature measurement and live video transmission allow continuous observation of underwater conditions and surrounding objects. The framework supports environmental data collection, surveillance, and exploratory tasks while maintaining simplicity and cost effectiveness. Experimental evaluation demonstrates reliable movement, effective communication, and accurate sensing capabilities, making the system suitable for educational, research, and water resource management applications in diverse aquatic environments.
