In addition, the plurality of LIDAR sensors 112 are configured to continuously scan the surrounding environment and generate a real-time 3D map to the flight controller, which interprets the received data and identifies the location and size of obstacles. Moreover, when the obstacle is detected within a critical range, the flight controller adjusts the flight path of the hand-held foldable drone 102 to avoid collision. Advantageously, the plurality of LIDAR sensors 112, such as the first LIDAR sensor 112A, the second LIDAR sensor 112B, the third LIDAR sensor 112C, and the fourth LIDAR sensor 112D enhances the ability of the hand-held foldable drone 102 to operate in confined and cluttered spaces thereby reducing the risk of collisions and damage. FIG. 3 is a diagram illustrating an exemplary scenario of an implementation of a hand-held foldable drone in a military operation, in accordance with an embodiment of the present disclosure. FIG. 2 is described in conjunction with elements from FIG. 1. With the reference to the FIG. 2, there is shown a diagram 300 that illustrates an implementation of the hand-held foldable drone 102 in the military operation.

[0056] In an implementation scenario, an operator 302 operates the hand-held foldable drone 102 through the ground control unit 104 by the single hand. At first, the handheld foldable drone 102 is unfolded by the operator 302, such as by pressing a mechanical button of the hand-held foldable drone 102, after connecting the ground control unit 104 to the hand-held foldable drone 102, thereby configuring the handheld foldable drone 102 for a mission (e.g., the military operation). Furthermore, the drone utilizes the obstacle detection and avoidance provided by the integrated command and control system 100 through the plurality of LIDAR sensors 112. A continuous video feed is provided to the operator 302 on the display 120 of the ground control unit 104, which is captured by the camera 126 of the hand-held foldable drone 102 for a safe execution of the mission by the operator 302. Moreover, when the hand-held foldable drone 102 reaches a particular suitable location, which is target 304 set intended by the operator 302, the operator 302 sends a detonate signal to the hand-held foldable drone 102 through the ground control unit 104. Thereafter, upon receiving the detonate signal, the hand-held foldable drone 102 detonates the explosive to the target 304 with precision and successfully completes the mission. Advantageously, by ensuring a successful detonation of the explosive in the military operation, the integrated command and control system 100 provides an operational and tactical effectiveness, safety, agility, and ease of use of the hand-held foldable drone 102.

[0057] FIG. 4 is a flow chart illustrating operations to be performed for avoiding obstacles during the flight of the hand-held foldable drone, in accordance with an embodiment of the present disclosure. With reference to FIG. 4, there is shown a flowchart 400 illustrating the operations to be performed for avoiding obstacle during the flight of the hand-held foldable drone 102.

[0058] At operation 402, the obstacle avoidance process is initiated by allowing the handheld foldable drone to 102 start the flight. At operation 404, the hand-held foldable drone 102 configured to move through an original route and at operation 406, the hand-held foldable drone 102 configured to check whether any obstacle is detected or not. Moreover, if any obstacle is not detected, the hand-held foldable drone 102 is configured to continue moving towards the original route and if any obstacle is detected, then, in that case, the hand-held foldable drone 102 is configured to check that, if the detected obstacle is closer than the pre-determined critical distance or not, such as at operation 408. If the detected obstacle is not closer than the predetermined critical distance, then the hand-held foldable drone 102 continues to move in the original path but if the detected obstacle is closer than the predetermined critical distance, then, in that case, at operation 410, the hand-held foldable drone 102 is configured to alert the operator 302 about such detection. Furtehrmore, at operation 412, the hand-held foldable drone 102 is configured to stop moving towards the detected obstacle and change the path, such as by alerting the operator 302 about such deviation at operation 416. Finally, at operation 414, the obstacles are avoided and the hand-held foldable drone 102 reached the intended target. Advantageously, the hand-held foldable drone 102 is configured to detect obstacles and make real-time decisions to avoid the obstacles, thereby enhancing the reliability and safety of flight of the hand-held foldable drone 102. Additionally, the clear communication of the hand-held foldable drone 102 with the operator 302 throughout the flight ensures that the operator 302 is always aware of the status and actions of the hand-held foldable drone 102, providing an additional layer of control and oversight to the operator 302.
