Turtlebot3 DRL Navigation

Extended an existing Deep Reinforcement Learning navigation framework to support the TurtleBot3 platform with realistic 2D LiDAR observations, and migrated the full system from ROS 1 to ROS 2. The project enables training DRL agents for goal-directed mobile robot navigation with obstacle avoidance in Gazebo, using LiDAR-based state representations and velocity-based control tailored to TurtleBot3…
