Abstract: The present invention relates to a compact Unmanned Aerial Vehicle (UAV), hereafter referred to as the LIDAR Drone, developed to address the major shortcomings of existing micro-drone navigation systems used in indoor or congested environments. Conventional small drones generally depend on ultrasonic sensors for obstacle detection and altitude stabilization. These sensors often suffer from poor accuracy, slow response times, and inconsistent readings, which lead to unreliable control and frequent collisions, especially when operating near walls, shelves, equipment,. or_ moving objects Tq_overcome these limitations; the proposed system incorporates a high-precision Time-of-Flight (ToF) LIDAR module integrated into a dual-microcontroller architecture. A dedicated low-power microcontroller continuously acquires high-frequency distance measurements from the LIDAR sensor and processes them in real time. The filtered and interpreted distance data is then translated into a variable sensory feedback signal specifically, a frequency-modulated buzzer output and a corresponding LED blink rate. This allows the operator to intuitively understand the proximity of surrounding obstacles through simple auditory and visual cues. By enabling centimetre-level distance estimation and delivering instantaneous feedback, the system significantly improves manual flight stability, obstacle avoidance, and altitude hold performance. The invention is particularly effective in GPS-denied or cluttered environments, offering a cost-efficient yet high- performance solution suited for indoor inspection, warehouse inventory operations, and complex search-and-rescue missions where precise close-range navigation is essential
