Gazebo
Gazebo is an open-source 3D physics simulator widely used in robotics research and development. It is deeply integrated with ROS (Robot Operating System) and supports complex robot kinematics, dynamics, and sensor simulation.
Timeline (last 90 days)
Compared to general-purpose simulators such as Gazebo, MuJoCo has advantages in computational speed and numerical stability, but requires precise description of robot parameters in MJCF (XML format).
PAANI connects the local AI pipeline to an independent Gazebo simulated vessel, localization, and control testbed via a ROS 2 interface, forming a closed-loop simulation validation environment.
Mainstream physics engines include MuJoCo (high-precision contact dynamics), PyBullet (open-source lightweight), Isaac Gym (GPU-parallel acceleration), and Gazebo (ROS ecosystem integration), among others.
Gazebo has a steep learning curve, and configuring ROS, SDF models, and various plugins is not beginner-friendly
Gazebo has a large number of ready-made drone models (such as PX4 SITL) that can be directly reused
Gazebo simulation speed is slow; high fidelity brings high computational overhead, which may become a bottleneck for scenarios requiring hundreds of RL experiments
RL training in Gazebo requires building a Gym interface for bridging on your own
The essence of choosing a simulation platform is a trade-off between RL training efficiency and physical fidelity
If the team plans to migrate to real drones or has higher requirements for sensor-level perception, Gazebo should be prioritized
The recommended middle-ground strategy is to first use gym-pybullet-drones to quickly validate algorithm feasibility, then conduct a small amount of high-fidelity validation or sim-to-real testing in Gazebo
