Autonomous landing on Moving PLatform using DDPG

Deep reinforcement learning for drone precision landing, docker container for simulation in Gazebo-ROS2 dashing with PX4-Autopilot controller.

Usage

To start the docker run:

For ROS2 Dashing:
```
./run_docker.sh run
```

Test

Open 2 terminals and run the docker in each one of them, as explained above.

In the first one run:

ros2 run px4_ros_extended gazebo_runner.py --test --headless

Agent

In the second one run

cd /src/shared
./launch_test_ddpg.sh 0 small 6 3 4500

Simulation video

The simulation video for this implementation can be found at this link in which the landing platform is moving linearly. Another simulation video link shows landing of UAV on still platform.
