|---|---|---|---|---|---|---|
| NVIDIA Isaac Sim + Isaac Lab | NVIDIA | Apache-2.0 (composants Omniverse Kit propriétaires) | yes | PhysX 5 (+ moteur Newton intégré dans Isaac Lab) | yes | yes |
|
Isaac Sim 5.0 and Isaac Lab 2.2 reached general availability at SIGGRAPH 2025, with the Isaac Sim application open-sourced on GitHub under Apache-2.0 (the underlying Omniverse Kit remains closed source). It is the de facto industry platform for humanoid and manipulation policy training, now compatible with the Newton physics engine.
Uses : RL training, synthetic data, sim2real, digital twin

| MuJoCo | Google DeepMind | Apache-2.0 | yes | MuJoCo (moteur natif, contacts articulés) | yes | n/a |
|
Open-sourced by DeepMind in 2022, MuJoCo remains the most cited physics engine in robot learning research; the 3.x series added MJX for accelerator hardware, and MuJoCo Warp (GPU-optimized, up to ~70x faster on humanoids) also powers a solver inside NVIDIA's Newton engine.
Uses : RL training, sim2real, model-based control, benchmarking

| Genesis | Genesis AI (issu d'un projet académique multi-universités) | Apache-2.0 | yes | Moteur multi-physique unifié maison (rigide, MPM, SPH, FEM, PBD) | yes | n/a |
|
Launched in December 2024 as an academic collaboration, Genesis became one of the fastest-adopted robotics simulators ever and its development is now backed by the startup Genesis AI (repackaged as genesis-world). It loads MJCF, URDF and mesh formats and targets the full spectrum from rigid robots to soft-body and fluid simulation.
Uses : RL training, synthetic data, soft robotics, generative simulation

| Gazebo (nouvelle génération, ex-Ignition) | Open Source Robotics Foundation (Open Robotics) | Apache-2.0 | yes | Pluggable : DART (défaut), Bullet, TPE | no | yes |
|
Gazebo Jetty, the 10th major release, shipped on September 30, 2025 as an LTS supported until September 2030. Physics runs on CPU (GPU is used for rendering and sensors), which keeps it more suited to systems integration and testing than to massively parallel RL training.
Uses : CI testing, ROS development, digital twin, multi-robot simulation

| PyBullet / Bullet Physics | Communauté Bullet Physics (Erwin Coumans) | zlib | yes | Bullet | no | n/a |
|
Development has slowed to maintenance mode (latest release 3.2.7, January 2025) and most new RL research has migrated to GPU-native simulators, but PyBullet remains widely used in education and as a lightweight CPU baseline.
Uses : RL training, prototyping, education, benchmarking

| Webots | Cyberbotics | Apache-2.0 | yes | ODE (fork Open Dynamics Engine) | no | yes |
|
Born at EPFL in 1996 and open-sourced in December 2018, Webots is the leading European (EMEA) robot simulator; the latest stable release R2025a (February 2025) added new robot models and improved ROS 2 support, with nightly builds still active in 2026.
Uses : education, prototyping, ROS development, competitions

|
Successor to V-REP, developed in Switzerland; version 4.10 shipped in May 2025. The Edu edition is free but restricted to schools and universities, while commercial use requires a CoppeliaSim Pro license.
Uses : prototyping, education, factory simulation, algorithm validation

|
Announced at GTC in March 2025 and released in open beta at CoRL 2025 under Linux Foundation governance, Newton is the major new entrant of 2025-2026: it plugs into Isaac Lab and MuJoCo Playground, and is already used by Skild AI and Samsung for fine manipulation and deformable-object training.
Uses : RL training, sim2real, differentiable physics, deformable simulation
