Designed for complex environmental interactions and adaptive flight path management, it aims to push the boundaries of what autonomous drones can achieve in realistic and simulated settings. 5 | 6 | ## Features 7 | - **Real-Time Obstacle Detection**: Utilizes advanced sensors and AI to dynamically detect and avoid obstacles. 8 | - **Environmental Interaction**: Engages with simulated environments to test response scenarios and improve navigational tactics. 9 | - **Adaptive Flight Path Management**: Algorithms dynamically adjust the drone's flight path based on real-time data. 10 | - **Simulation Integration**: Compatible with AirSim and Gazebo for high-fidelity simulation and testing. 11 | - **Safety and Emergency Protocols**: Robust mechanisms to handle emergency scenarios effectively. 12 | 13 | 14 | ## Planned Enhancements 15 | I am continuously working to improve the system's capabilities. Future enhancements include the integration of advanced pathfinding algorithms such as A* and Dijkstra’s. These enhancements will be integrated into the project's `navigation.py` file and will provide more efficient and optimized pathfinding solutions. 16 | 17 | **Note:** For detailed information on future enhancements and the planned implementation of A* and Dijkstra's algorithms, please refer to the `Future_Enhancements.md` file in the `docs` folder. This will give the users an idea on how the, "example usage" can look like. 18 | 19 | **Future Enhancements updates will be posted in `Future_Enhancements.md` file in the `docs` folder.** 20 | 21 | ## Installation 22 | Ensure you have the following prerequisites installed: 23 | - Python 3.8 or later 24 | - Unreal Engine 25 | - AirSim or Gazebo 26 | 27 | Clone the repository: 28 | git clone https://github.com/nikulram/Advanced-Autonomous-Drone-Navigation-System.git 29 | 30 | cd Advanced-Autonomous-Drone-Navigation-System 31 | pip install -r requirements.txt 32 | 33 | ## Usage 34 | To start the simulation environment: 35 | python main.py 36 | 37 | Replace main.py with the script configured to launch your simulation environment, tailored to your specific setup in either AirSim or Gazebo. 38 | 39 | ## Testing 40 | All testing files are located within the same directory as their corresponding modules.

It explains the planned implementation of A* and Dijkstra’s algorithms, their respective use cases, and the reasons for their current absence in the project. 7 | 8 | ## Pathfinding Algorithms: A* and Dijkstra's 9 | 10 | ### What is A* Algorithm ? 11 | 12 | A* (A-Star) is a pathfinding algorithm used to find the shortest path between a start and an end point. It uses a heuristic to guide its search, making it faster and more efficient, especially in large graphs.(Hart, P.E., Nilsson, N.J., Raphael, B., 1968). 13 | 14 | #### Implementation 15 | 16 | Below is the implementation of the A* algorithm. This code will be integrated into the project's 'navigation.py' file.: 17 | 18 | import heapq 19 | 20 | class AStarPlanner: 21 | def __init__(self, grid): 22 | self.grid = grid 23 | 24 | def heuristic(self, start, end): 25 | return abs(start[0] - end[0]) + abs(start[1] - end[1]) 26 | 27 | def get_neighbors(self, node): 28 | neighbors = [(0, 1), (1, 0), (0, -1), (-1, 0)] 29 | result = [] 30 | for n in neighbors: 31 | neighbor = (node[0] + n[0], node[1] + n[1]) 32 | if 0 <= neighbor[0] < len(self.grid) and 0 <= neighbor[1] < len(self.grid[0]) and the grid[neighbor[0]][neighbor[1]] == 0: 33 | result.append(neighbor) 34 | return result 35 | 36 | def a_star(self, start, end): 37 | open_list = [] 38 | heapq.heappush(open_list, (0 + self.heuristic(start, end), 0, start, None)) 39 | g_scores = {start: 0} 40 | parents = {} 41 | 42 | while open_list: 43 | current = heapq.heappop(open_list)[2] 44 | 45 | if current == end: 46 | path = [] 47 | while current: 48 | path.append(current) 49 | current = parents.get(current) 50 | return path[::-1] 51 | 52 | for neighbor in self.get_neighbors(current): 53 | tentative_g_score = g_scores[current] + 1 54 | if tentative_g_score < g_scores.get(neighbor, float('inf')): 55 | g_scores[neighbor] = tentative_g_score 56 | f_score = tentative_g_score + self.heuristic(neighbor, end) 57 | heapq.heappush(open_list, (f_score, tentative_g_score, neighbor)) 58 | parents[neighbor] = current 59 | return [] 60 | 61 | 62 | ### What is Dijkstra’s Algorithm ? 63 | 64 | Dijkstra’s algorithm is used to find the shortest paths between nodes in a graph. It does not use a heuristic and is optimal for graphs with uniform edge weights. (Dijkstra, E.W., 1959). 65 | 66 | #### Implementation 67 | 68 | Below is the implementation of Dijkstra’s algorithm. This code will also be integrated into the project's navigation.py file.: 69 | 70 | 71 | import heapq 72 | 73 | class DijkstraPlanner: 74 | def __init__(self, grid): 75 | self.grid = grid 76 | 77 | def get_neighbors(self, node): 78 | neighbors = [(0, 1), (1, 0), (0, -1), (-1, 0)] 79 | result = [] 80 | for n in neighbors: 81 | neighbor = (node[0] + n[0], node[1] + n[1]) 82 | if 0 <= neighbor[0] < len(self.grid) and 0 <= neighbor[1] < len(self.grid[0]) and the grid[neighbor[0]][neighbor[1]] == 0: 83 | result.append(neighbor) 84 | return result 85 | 86 | def dijkstra(self, start, end): 87 | queue = [(0, start)] 88 | distances = {start: 0} 89 | parents = {start: None} 90 | 91 | while queue: 92 | current_distance, current_node = heapq.heappop(queue) 93 | 94 | if current_node == end: 95 | path = [] 96 | while current_node: 97 | path.append(current_node) 98 | current_node = parents[current_node] 99 | return path[::-1] 100 | 101 | for neighbor in self.get_neighbors(current_node): 102 | distance = current_distance + 1 103 | if distance < distances.get(neighbor, float('inf')): 104 | distances[neighbor] = distance 105 | heapq.heappush(queue, (distance, neighbor)) 106 | parents[neighbor] = current_node 107 | 108 | return [] 109 | 110 | 111 | ### Integration and Usage 112 | 113 | These pathfinding algorithms will be integrated into the `navigation.py` file of the project. Users can choose which algorithm to use based on their specific requirements: 114 | 115 | - **A* Algorithm**: Best used when a heuristic can be applied to guide the search, making it faster for larger grids. 116 | - **Dijkstra’s Algorithm**: Optimal for graphs with uniform weights or when a heuristic is not available. 117 | 118 | #### Example Usage in 'navigation.py'.: 119 | 120 | 121 | from pathfinding import AStarPlanner, DijkstraPlanner 122 | 123 | class Navigation: 124 | def __init__(self, grid): 125 | self.a_star_planner = AStarPlanner(grid) 126 | self.dijkstra_planner = DijkstraPlanner(grid) 127 | 128 | def find_path(self, start, end, method='a_star'): 129 | if method == 'a_star': 130 | return self.a_star_planner.a_star(start, end) 131 | elif method == 'dijkstra': 132 | return self.dijkstra_planner.dijkstra(start, end) 133 | else: 134 | raise ValueError("Unknown method: choose 'a_star' or 'dijkstra'") 135 | 136 | # Example usage can be : 137 | if __name__ == "__main__": 138 | grid = [ 139 | [0, 1, 0, 0], 140 | [0, 1, 0, 1], 141 | [0, 0, 0, 0], 142 | [1, 1, 0, 0] 143 | ] 144 | navigator = Navigation(grid) 145 | path = navigator.find_path((0, 0), (3, 3), method='a_star') 146 | print("Path found using A*:", path) 147 | path = navigator.find_path((0, 0), (3, 3), method='dijkstra') 148 | print("Path found using Dijkstra's:", path) 149 | 150 | 151 | ### Reasons for Current State 152 | 153 | Due to time and resource constraints, I have not yet trained models or integrated these algorithms fully into the operational system. The current focus has been on establishing a strong foundational framework and simulating basic functionalities. 154 | (NOTE : FUTURE UPDATES WILL POSSIBLY BE GIVEN IN THIS FILE) 155 | 156 | 157 | ### References 158 | 159 | Hart, P.E., Nilsson, N.J., Raphael, B.
