A reinforcement learning system for drone navigation using the Q-Learning algorithm. Written in Python and tested in V-REP. Run the main3.py Python script while running drone_scene1_V2.ttt in V-REP. There are two videos in the repository. QL_Drone_V1.mp4 shows the drone just after the program starts. QL_Drone_V2.mp4 shows the drone after about 15 hours of training.
