... Hi, The problem you describe might come from the fact that the simulation is not synchronized with the robot (check the synchronization field of the ...
Hello, Webots 4.0.19 was just released. It is now available for download at http://www.cyberbotics.com/products/webots/download.html I appreciate your feedback...
Dear Mr. Michel, Although I am now able to start Webots 4.0.19 without the -sync option needed on my Red Hat Linux 7.3 in version 4.0.18, the following fatal...
Dear Rainer Paine, Unfortunatelly, I don't have a Khepera with such floor sensors here, so I cannot try to reproduce exactly your problem. Does this problem...
Dear Mr. Michel, The Khepera has one floor sensor which is accessed as described by Mr. Zufferey. From the serial terminal, the sensor is accessed by "I,3". I...
When using a simulated floor sensor in Webots 4, the following problem occurs. If the ground is defined as a transform, then the floor sensor (fs0 in the world...
Dear Rainer Paine, Thank you for providing a solution to this problem. Actually, the floor sensors are instances of DistanceSensor. I believe that if you tune ...
Dear Mr. Michel, Thank you for the suggestion about tuning the lookup-table of the floor sensor. I modified the color sensor table from the rover.wbt example...
... No this is a known bug of the Mac OS X version. We are working on these problems and they will be hopefully fixed in the next version to be available with...
Hi, Thanks for your quick answer. In fact I was testing the evaluation version of webots for MacOSX while we were waiting for a full featured Linux version. In...
I am presently doing a projection that invloves Khepera simulating swarm behaviour.For a part of it, I have to get the Khepera to a specific point on a plane...
Sorry for the ineptness on this one, but going through the manuals and doing some cursory looking around the scene tree and the controllers, I can't seem to...
I am using cygwin on Windows to run Webots. I modified the makefile to get rid of the ming stuff and added in a -mno-cygwin so that the webots would load and...
... That seems to be all right. You could also have copied the cygwin1.dll into the C:\Program Files\Webots\lib directory and removed the -mno-cygwin compiler...
... It is not defined. It's automatic. The robot window is hardcoded for the Khepera robot. In other cases, the robot window displays automatically the servo...
Does anyone out there know what is the best method for accurately calculating the position and orientation of the khepera robot? Assume that the robot must not...
Hi, I would recommand to use the GPS device which is included with Webots 4 to get an exact position estimation for the robot. Otherwise, you should use the...
Hi to everybody! I need to develop a model which consist on a cable hanging between two posts. From that cable a robot will be hanging. I mean with cable just...

... The difficult part of this is probably the model of the cable. You should probably try to model it as a chain of long-box-shaped Servo nodes belonging to a...
Hello to everybody! I'm trying to develope a scene with a robot hanging from a rope. I don't know how to model the rope physics. It's enough setting the...
