Webots is one of the oldest and most mature commercial robot simulators, developed since 1996 by the Swiss company Cyberbotics as an EPFL spin-off. In December 2018 — together with the 2019a release — the simulator was released under the Apache 2.0 license as fully fledged open-source software, while preserving its commercial development model.
The Webots architecture is built on ODE (Open Dynamics Engine) with proprietary extensions for contact accuracy and motor simulation; rendering uses OpenGL 3.3 with optional PBR (physically-based rendering) support. Webots supports a broad catalog of ready-made robot models (NAO, Pepper, e-puck, TurtleBot, Pioneer 3-AT, Khepera, Atlas, Spot, Universal Robots, KUKA, Franka) and thousands of PROTO objects (parameterized prototypes).
APIs are available in C/C++ (native), Python (recommended), Java, MATLAB, JavaScript (HTTP), as well as full integration with ROS 2 through webots_ros2 (the official package, supported for Humble/Iron/Jazzy). Webots runs cross-platform on Linux, Windows, and macOS — which sets it apart from Gazebo (mainly Linux).
Simulation software is used for modelling, testing, and validating robot behaviours, sensor characteristics, environments, and algorithms without requiring physical hardware. It enables safe, repeatable, and cost-effective development cycles. Common robotics simulators include Gazebo, Isaac Sim (NVIDIA), MuJoCo, PyBullet, and Webots, each offering different trade-offs between physics accuracy, rendering fidelity, and integration with middleware frameworks such as ROS 2.
A Developer Tool is software designed to support the development workflow, including configuration, debugging, testing, monitoring, validation, and integration of robotic and embedded systems. Examples include IDE plugins, visual debuggers, log analysers, hardware-in-the-loop (HIL) test harnesses, and code-generation utilities specific to robotics platforms.
A family of open-source and commercial physics simulators for robotics: Gazebo, Webots, MuJoCo, PyBullet, Isaac Lab, CoppeliaSim, Genesis, and related tools. Common denominator: rigid-body physics engine, URDF/MJCF model support, ROS/ROS 2 integration, sim-to-real transfer.
