gazebosim/gz-sim is an open source robotics simulator that presents itself as the latest version of Gazebo. It provides Gazebo's robot physics and sensor simulation server and GUI, and runs the behavior of robots and their surrounding environment together with sensor observations virtually. The current latest release is gz-sim10_10.0.0.
It is a simulation environment for testing behavior and observations without moving a real robot. This repository handles high-fidelity physics simulation and rendering together, and provides several kinds of sensors and noise models. A noise model is a model that mixes error and jitter into observed values. The simulation is accessed not only through the GUI but also through plugins, asynchronous message passing and services. It is derived from Gazebo Classic and forms part of the Gazebo project. It is written in C++ and released under the Apache-2.0 license. It has 1544 stars, and the repository was created on April 15, 2020.
However, what can be verified here ends here. The fact that gz-sim10_10.0.0 is the latest release is shown, but the changes contained in this version are not given. The record contains no performance figures and no comparison material with other robotics simulators. The momentum score is low at 1.7 points, and the novelty, technology and quality scores are not filled in. It is a simulator with a clear feature scope and license, but what this version changed cannot be known until the release notes are checked.
