This paper presents the design and fabrication of a low-cost, manually operated, tethered remotely operated vehicle (ROV) for basic underwater exploration and visual inspection. The ROV is intentionally limited to a simple propulsion and control architecture rather than advanced autonomous functions. It uses two identical horizontal brushed DC underwater thrusters, an Arduino Uno controller, an L293D H-bridge motor-driver stage, two joystick modules, a 12 V 3000 mAh battery, a transparent ABS JB2 junction enclosure, and a front-mounted waterproof automotive/rear-view type camera. Each joystick independently controls one thruster, providing confirmed forward and reverse operation. A 15-ft wired tether carries power, control, and camera/video connections to the surface, where a USB capture card and laptop provide live visual monitoring. The enclosure is specified by its manufacturer as IP65/IP67; this rating is treated only as an enclosure specification and not as certification of the complete fabricated ROV. The recorded ROV cost is approximately ₹12,330. The paper discusses the mechanical arrangement, propulsion concept, electrical architecture, buoyancy principles, camera-based inspection workflow, motor-driver limitation, fabrication, and confirmed ROV observations. No unmeasured vehicle speed, thrust, operating depth, runtime, leakage duration, or camera-performance values are presented. The resulting platform is intended as a simple and accessible basis for water-tank inspection, underwater exploration, educational robotics, and small-scale observation, with more advanced sensing and control reserved for future work.
