Webots relies on an extended version of the ODE physics engine which was improved on several aspects:
- The contact points computation was improved to provide more accurate collisions and an increased stability.
- The cylinder geometric primitive was redesigned from scratch to fix collision and stability problems.
- A simple fluid dynamics capabilities was added to facilitate the simulation of drones and underwater robots.
- Several optimizations were implemented, including multi-threading.
Several simulation models provided in Webots are calibrated against their real counterparts. This include various objects, sensors, actuators and robots. The calibration process consists in adjusting the physical parameters of objects and devices so that they behave like their physical counterparts. These physical parameters include the mass distribution, the friction coefficients, the bounding objects, the spring and damping properties, etc. Users can calibrate their own models to ensure realistic simulation results.
Webots allows you to quickly build various mechanical architectures of robots, including:
- Articulated robots (legged robots, robotics arms)
- Wheeled robots (Ackermann cars, differential drive)
- Flying robots (quadcopters, helicopters, planes)
- Swimming robots (boats, submarines, salamanders)
- Modular robots (based on mechanical connector devices that can lock and unlock)
Multi-agent simulations can mix many different kinds of robot in the same simulation world.
Webots comes with libraries of calibrated models which you can re-use in your own simulations, or enrich with your own creations:
- Robots: NAO, PR2, Altas, Pioneer 3-DX, Robotis OP2, e-puck, Thymio II, Aibo and more.
- Sensors: Camera, Lidar, Distance Sensors, Radar, GPS, Accelerometer, Gyro, Radio Receiver and more.
- Actuators: Rotational and Linear Motors, Servo, Gripper, Radio Emitter, LED, Display and more.

- TCP/IP: interface with any robot controller system running possibly on a remote machine.
Similarly to robot programming, a user can program a simulation supervisor that will automate things during a simulation run, like move objects, reset positions of robots, store trajectory of robot, etc.
It is also possible to program a Physics Plugin to customize the physics of a simulation to add for example extra forces or torques (wind, perturbations) or handle contacts differently with for example some non-uniform friction model.
All these APIs are available directly from the Webots integrated development environment (IDE) that includes a source code editor and a scene tree editor. It is also possible to use these APIs from your favorit IDE.
Webots is available for Windows, Ubuntu Linux and macOS.
It runs pretty well on a standard laptop computer, but will reveal all its power on a desktop machine equiped with a modern graphics card. More details are provided in the Webots System Requirements.

The INTRA indoor robot simulator was developed by Cyberbotics on behalf of the INTRA group (EDF, CEA, Areva) to train pilots of the EOLE and EROS remote controlled robots. These robots are designed to operate indoor in case of a nuclear accident. They are able to climb up and down stairs, pass over pipes, open doors, grasp objects, press buttons and rotate valve wheels. The robots have several onboard cameras equipped with lights whose point of view is displayed on control screens at the remote control station. The simulation was designed to be a replica of the real system and can be operated from the same control console as the real system. It permits an initial training of pilots without taking risks of damage on the real hardware.
The NAO for Webots simulation model was developed by Cyberbotics on behalf of SoftBank robotics (formerly Aldebaran robotics) to model a NAO humanoid robot in Webots. The model was carefully calibrated against real NAO robots to ensure that simulated robot controllers could smoothly transfer to the real world. An interface with Aldebaran NAOqi Operating System was implemented to connect the simulated model to the Choregraphe graphical programming software as well as the C++ NAOqi API. The simulated NAO model simulates all the servo motors of the real robot, including the fingers ; it also simulates the two on-board cameras, the sonar, the LEDs, the motor position and force-feedback, the IMU (accelerometer and gyro), the touch sensors in the head and force sensors in the feet of the robot.
The Sony Aibo simulator is a simulation model of the Sony Aibo robot. It was developed with Cyberbotics' proprietary technology for Sony Digital Creatures Lab, to design and test behaviors for Aibo. A soccer game system has been implemented, allowing the Aibo to track a colored ball with its on-board color camera. Resulting controllers could be transfered to real Aibo robots.
