Terrain generator for Webots available online

A new tool for Webots is available online at http://www.cyberbotics.com/terrain_generator/. It allows you to generate a realistic simulation of an outdoor terrain based on a texture satellite image from Google Maps and real altitude data from GeoNames. The result is a Webots world containing a textured mesh (IndexedFaceSet) representing the terrain you selected. You can choose any location on Earth, adjust the zoom level, display a satellite, map or hybrid map, adjust the resolution of the mesh and choose between 3 different altitude databases. Then, you can open this world file in Webots and add robots to populate this terrain.

RoadNarrows Robotics to exhibit Webots at IROS 2009 in St. Louis

RoadNarrows robotics will be exhibiting Webots at IROS 2009 in St Louis, MO, USA from October 11th to October 15th. The people at RoadNarrows will be pleased to show you some demos of Webots and answer your questions. They also sell a number of mobile robots including the e-puck robot.

Robotstadium as a teaching tool

Some teachers expressed their interest to use the robotstadium competition setup in their robotics or computer science class. Robotstatdium is a free simulated robot programming competition based on the Webots software, the Nao humanoid robot and the Standard Platform League (SPL) of the RoboCup soccer competition. The competition runs online. Matches are played every business day and are visible in real time through a webcam system. It turns out to be a very appealing (not to say addictive) competition to students addressing several high level AI and robot control challenges while representing a miminal setup effort for teachers. If you are interested as a teacher, just drop us an e-mail at info@... and we will get back to you.

Soccerbots lean how to fall gracefully

Up until now, most work with humanoid robotics has focused on keeping them upright and balanced, but in the real world, falling down is inevitable. So now researcher in Chile are looking at teaching their Soccerbots how to fall down gracefully to minimize damage and allow for a quick recovery. According to a New Scientist article, 'They found that one of the main ways to minimise damage is for the robot to fold its legs underneath it. Among other things, that means the robot is much less likely to hit its head on the ground. Another good strategy is to use a fall sequence consisting of several movements, so the falling body has several points of contact with the ground, spreading the energy of the impact over a large number of joints, rather than taking it all in one disastrous crunch.'

Robotstadium: watch matches online from 3pm (CEST) through our new webcam!

Webots 6.1.0 released!

Webot 6.1.0 is available for download for Linux 32, Linux 64, Mac OS X and Windows! This new version adds new features and fixes a number of bugs of the previous version (6.0.1). It introduces a new Display device to simulate a screen on which the robot controller can draw any text or graphics, adds support for a native Matlab programming interface for the robot and supervisor controllers, includes sample simulations used in the Cyberbotics' Robot Curriculum as well as a new model of the Nao robot (V3) and associated Robotstadium simulation setup. The complete change log is available here.

Cyberbotics' Robot Curriculum

Nicolas Heiniger completed the Cyberbotics' Robot Curriculum during his master thesis and published it as a wiki book. This book is intended to students, teachers, hobbyists and researchers interested in intelligent robots. It helps understanding what robots are and how to program them. It is illustrated by the use of Webots and the e-puck robot. It includes two parts: a short theoretical part and a longer practical part. The practical part is composed of one chapter about the computer configuration and five chapters of exercises corresponding to five levels of difficulty from simple obstacle avoidance to Self Localization and Mapping (SLAM). After reading this book, the reader should be able to design his/her own intelligent robots. You are welcome to contribute to this book which is released under a copyleft license agreement.

Robotstadium competition about to start again!

The 2009 edition of the robotstadium competition, based on the Nao robot and the Standard Platform League (SPL) of the RoboCup soccer competition, is about to start with the release of Webots 6.1.0! The simulation includes a completely redesigned and improved robot model corresponding to the new V3 Nao robot which includes two cameras instead of one, an improved referee implementation (including an improved throw-in rule). The robotstadium simulation has also been optimized regarding the foot sensors of the robot and it overall runs now approximately 10% faster than the previous simulation.

Webots 6.0.1 released!

Webot 6.0.1 is available for download for Linux 32, Linux 64, Mac OS X and Windows! This new version fixes a number of bugs of the previous version (6.0.0), adds more possibilities to the free Nao / Robocup / robotstadium simulation model to reset the position of the robot and the ball (useful for iterative learning algorithms), improves the text editor with a new comment / uncomment feature, restores the selection status of the scene tree after a revert operation, etc. The full change log is available here. Please note that URBI support is broken since Webots 6.0.0. We hope to restore this in the next release of Webots to be made available in February.

Roombot modules simulations

Michael Mayer and Alexandre Tuleu from the BIRG have developed nice simulations models for modular robots called Roombots. Each pair of modules composing a Roombot robot has 6 degrees of freedom, allowing them to self-configure robustly and create very interesting shapes autonomously. Their Webots simulations allowed them to explore the possible moves in space of these Roombot modules as well as inverse kinematics. A series of movies show the Roombot modules self-configuring into a chair, reaching different locations and orientations on the floor using inverse kinematics, etc. They also had to develop a Webots physics plug-in to handle the special shape of their modules for collision detection.

Nao Robocup soccer simulations

Giuseppe Certo from BIRG has developed a series of improvements and tools for the Nao Robocup soccer simulation. He used the motion editor provided with Webots 6 to create new motions, including a stand up motion for the Nao robot, various shoot motions and a very efficient goal keeper diving motion which is fired when the goal keeper robot detects the ball going towards one or the other side of the goal. He also contributed to improve the automatic referee by improving the throw-in system and implementing the illegal defender rule.

Webots 6.0.0 released!

Webot 6.0.0 is available for download for Linux 32, Linux 64, Mac OS X and Windows! Webots 6 features many great improvements on the Webots 5 series, including a new graphical user interface with a main window including sub-windows, a new reworked programming interfaces (in C, C++, Java, Python, URBI), a more powerful supervisor API, new devices (Gyro, Compass, reworked GPS and Accelerometer), a built-in motion editor and many small improvements and bug fixes. Regular users of Webots 5 under the terms of their Premier service will be able to upgrade free of charge.

Stewart plaform simulation

Yvan Bourquin developed a Webots simulation model of a Stewart platform. A Stewart platform is a kind of parallel manipulator using an octahedral assembly of struts. A Stewart platform has six degrees of freedom (x, y, z, pitch, roll, and yaw). In this example, the Stewart platform is loaded with a few stacked boxes, then the platform moves and the boxes stumble appart. This simulation uses a physics plug-in to attach both ends of the linear actuators (hydraulic pistons) to the lower and the upper parts of the Stewart platform. Webots 6 includes all the sources files for this simulation model (world file generator, physics plug-in and robot controller).

The Rat's Life contest has recently hit a major milestone with Ratatouille: a clever competitor performing an efficient SLAM (Simultaneous Localization And Mapping) algorithm to accurately remember the location of feeders in the maze (see movies). Ratatouille currently stands at the top of the Hall of Fame filled with 25 competing teams. The contest is still open to new comers, this leaves you maybe a chance to try to challenge Ratatouille...

A new release of Webots is available for download on our web site. This new version includes updates for the Rat's Life and the Robotstadium competitions. It also features several bug fixes and includes a multi-threaded physics simulation for an outstanding performance on multi-core processor (up to 3x faster on quad-core processor, currently available for the Robotstadium Nao simulations only). The complete change log is available here.

Robotstadium contest launched!

Video: Passive dynamic walker simulation in Webots

The Robotstadium contest started on April 21st. So far we have 56 registered users, but only one of them (Ted) has submitted a controller program for his team of soccer playing Nao robots. His challengers are under preparation here and there. You are welcome to join this promising contest, submit your URBI and/or Java code and possibly win a Nao robot offered by Aldebaran robotics.

Sasha Voloshina from the university of Michigan, developed a nice simulation of a passive dynamic walker robot in Webots. This robot has no controller and only passive joints. Nevertheless, it can walk on an inclined surface in a very elegant way. The video of this simulation was published on cyberbotics web site.

Rat's Life contest running!

Free Nao Robocup simulation in Webots!

The new artificial life programming contest called "Rat's Life" is running now! So far, only 6 out of the 37 registered users submitted a first robot controller. This allowed us to start a first round and publish the very first simulation movies (see the Movie section of the web site). It's not too late to enter and compete with the first competitors. More information and registration at www.ratslife.org

The Aldebaran Robotics' Nao Robocup simulation, recently included in Webots is provided free of charge to any user of the demo version of Webots 5.7.3. Actually, 8 simulation worlds containing 1, 2, 4 or 8 Nao robots can be freely programmed to play soccer with either a C/C++ programming interface or a URBI programming interface. A soccer referee supervisor program manages the game.

Webots 5.7.3 released!

Webots and the first Asimov law

A new release of Webots is available for download on our web site. This new version facilitate the utilization of Webots for the Rat's Life contest and the free Nao Robocup simulation. It includes a new version of URBI (1.5.2) and introduces several new features and bugs fixes. The complete change log is available here.

Webots license agreement was recently modified to include the respect of the first Asimov law. This law ensure that "A robot may not injure a human being or, through inaction, allow a human being to come to harm.". This forbids any utilization of Webots to develop robots designed to harm people.

Spherical camera modeling in Webots

Katana 1.2 robot available for purchase

Simon Blanchoud implemented a sample Webots application using spherical cameras. Unlike plane camera which project the image on a plane, spherical camera project the image on a sphere. This is very useful for implementing panoramic cameras, or range finders like the SICK sensor. This sample application was included in Webots 5.1.12 in the sample/howto folder.

Neuronics released a major upgrade of their well known Katana robotic arm which is modeled in Webots. The new model has the same mechanical structure as the previous one, but the electronics was completely redesigned featuring a CPU board with real time Linux and various connection ports (USB, Ethernet, etc.). The new version of this robotic arm is available for purchase from Cyberbotics.

Webots 5.1.12 available for download

This new version of Webots includes a first version of the cross-compiler for the e-puck robot running on all platforms (e.g., Windows, Linux and Mac OS X). It also includes the spherical camera sample and fixes quite a few bugs. The complete change log is available here. You can download this new release from here.

Odor tracking with a swarm of robots

Talking Robots Podcast interview of Olivier Michel

Thomas Lochmatter and his Khepera III robot

Thomas Lochmatter from the SWIS research group at EPFL developed an interesting odor tracking system based on a swarm of small mobile robots able to identify odors and find their sources. This research could have interesting applications especially in demining fields where humans and animals could be replaced by robots. Read more in French or in German.

Markus Waibel from the Talking Robots Podcast interviewed Olivier Michel: "In this interview we talk to Olivier Michel, the founder of Cyberbotics Ltd., a company specialized in robot simulation, about his business experience [...]". The complete Podcast can be downloaded as an MP3 file (9MB).

Kondo KHR-2HV simulation using Webots (video)

Webots mentioned in Servo magazine

Laurent Lessieux wrote an interesting article in robots-dreams.com where he explains how he created a simulation of the Kondo KHR-2HV robot in Webots (and compares Webots to Microsoft Robotics Studio). The video shows an impressive series of movements that were designed for the real robot and that execute nicely in simulation. The work of Laurent will be included in an upcoming version of Webots. He also released a nice software called Webots Generator to help creating models in Webots from CAD files.

The Feburary issue of Servo magazine is featuring an article by Bryan Bergeron entitled "Robot Simulation: AI behaviors" which has a few nice words on Webots. From the article: "Robot simulation isn’t limited to research and development. Most factory robots ship with robot simulations that enable operators and programmers to work out process and coding challenges before potentially ruining a robot or jeopardizing an entire assembly line."

The Swiss Mobile Robotics Consortium is getting bigger

Bob II: training for Roboka contest

Founded end of 2004 by four companies from the Lake Geneva area (BlueBotics, Cyberbotics, FiveCo and K-Team), the Swiss Mobile Robotics Consortium is adding Neuronics (Zürich) and GCtronic (Mendrisio) to its membership, thus now representing all Swiss linguistic regions. Its members, offer innovative and complementary competences and technologies to meet the market requirements of any size and complexity.

We recently found on YouTube a very entertaining movie made with Webots (turn on the sound). From the description: "A little story about BobII (bob the second). A virtual robot who fought in the roboka competition 2004 and 2005, and won both :).. This video shows his very hard time in our genetic algorithms trying to learn how to walk and fight like a true robot killing machine..."

Hoap-2 robot playing the drums

High level activity control on Aibo / URBI / Webots

Sarah Dégallier, Cristina P. Santos, Ludovic Righetti and Auke-Jan Ijspeert published a paper entitled "Movement generation using dynamical systems: a humanoid robot performing a drumming task" at the Humanoids 2006 conference along with interesting videos where a real and a simulated HOAP-2 robot are playing the drums using a superposition, and switch between, discrete and dynamic rhythmic movements.

Dane Alexander from AIAI at Edinburgh university developed a Webots simulation of Aibo using the URBI programming language that allows for a high level activity control of the robot. This master thesis is publicly available on the web, including the Webots files. This is illustrated with a simulated Aibo robot navigating from one zone to another in a generic office environment, with zones representing rooms and open spaces.

Webots 5.1.11 available for download

Season's greetings & Christmas holidays

A nice movie (10 MB) of a Webots simulation of the Shrimp robot was added on Cyberbotics web site. This movie demonstrates the Shrimp climbing various types of obstacles, including stairs, and turning left and right.

We expect to receive our very first batch of e-puck robots from production by November 6th. We already sold out all of them and ordered another batch! In the meanwhile, we have been progressing on the development of the integration of the e-puck in Webots. The Bluetooth communication was improved and we progressed in the development of a multi-platform cross-compiler using the Webots API. We also published a new simulation movie (8 MB).

Khepera robot learning garbage collecting

Webots 5.1.10 released

Ricardo Tellez developed a modular neural network system allowing a Khepera robot to learn incrementally a number of tasks, including a garbage collecting behavior. A web site featuring simulation movies explains the details of this interesting research. The Webots source code is made available on the site as well as two scientific papers.

We just released Webots 5.1.10. You can review the change log here. This is a minor upgrade which fixes a number of small bugs and problems. Hence, we recommend to all Webots users to upgrade to this new version if they experience problems with their current version or if they want to stay on the bleeding edge of the Webots development! Any feedback on new releases is always greatly appreciated...
