       Mission Planner is a ground control station software designed for mission planning,monitoring, and control of unmanned vehicles. It is particularly associated with the Ardupilot open-source autopilot platform, which is used in a variety of unmanned vehicles, including drones (unmanned aerial vehicles or UAVs), rovers, boats, andmore. Mission Planner is widely used in the open-source community, especially with vehicles that run the Ardupilot firmware. It provides a user-friendly interface and a comprehensive set of tools for both novice and advanced users. Keep in mind that the specific features and capabilities of Mission Planner may evolve over timewith software updates and community contributions.

    2. User Interface:

    A User Interface (UI) refers to the point of interaction between a user and a computer system or a device. It encompasses everything that a user can interact withwhether it's physical hardware components or software applicationsand itplays a crucial role in facilitating effective communication and interaction. A well-designed user interface aims to be intuitive, efficient, and visually appealing. It considers user experience (UX) principles to ensure that users can interact with thesystem or application seamlessly and achieve their goals effectively. The field of user interface design is interdisciplinary, involving aspects of psychology, graphic design, human-computer interaction, and usability engineering.

    Real-time data visualization in a ground control station (GCS) involves the dynamicrepresentation of critical information from a drone during flight. Through intuitive graphical interfaces, operators can instantly monitor key parameters such as altitude, speed, battery status, and GPS coordinates.

    These visualizations often include interactive maps, telemetry graphs, and sensor readings, offering operators immediate insights into the drone's performance and environmental conditions. Real-time data visualization plays a pivotal role in enhancing situational awareness, enabling operators to make timely decisions and adjustments during drone operations for optimal control and mission

11. CONCLUSION

In conclusion, the integration of adaptable robotic systems designed for traversing diverse terrains, such as the Hybrid robot combining boat mobility with underwater capabilities, addresses the growing demand for advanced surveillance and exploration in defense scenarios.The challenges of monitoring vast territories, particularly across water bodies, have led to the development of innovative solutions. This hybrid robot, with its seamless transition between surface and underwater operations, emerges as a groundbreaking tool for enhanced observation, data collection, and monitoring.
