Goodmorning! I am trying to do something very simple with webots, following the "soccer" example. I have a flock consisted of DUCK_CARD=6 ducks, and I am...
Hi, See my comment below, in your source code: -Olivier ... // You should declare it as: float *emitter_buffer; // to make things simpler (see below) ... //...
... Sure, this is a known problem. ... I see. ... It is difficult to know which field should be reset to their initial value, as we may not want to reset the...
On Tue, 01 Jun 2004 17:34:41 +0200, Olivier Michel ... I see. Obviously I hadn't thought it through. Any ideas about why the touch sensor won't work with...
... This is strange indeed. I suspect this behavior is caused by the fact that your robot seems to be hoping from time to time into the ground. Hence the...
... I probably have to fix the doc about that : only the supervisor_node_was_found() has to be called after robot_step(), not supervisor_node_get_from_def(). I...
Thank you very much for your help, it was the exact solution to my problem (<first getting a pointer to the buffer, then loading the values>)... I am sooo...
Hi, I believe the ball is slowing down a little bit due to collisions... I would recommand you to play with the following parameters in the BALL Physics node...
Hi, my main robot(khepera) controller uses several support modules (.c and .h) files. I had them compiled and running in webots 4. I copied the Makefile.kros...
Hi, You should probably do the same for OBJ and INC (as you did with EXE): #EXE=$(addsuffix .s37,$(basename $(shell grep -wl main *.c *.s *.S *.cc 2>null))) ...
Thanks for the advice, just realised its not the Makefile.kros thats causing the problem. Rather, it seems that what compile in gcc may not compile in this...
Hi, I need to use Webots for a research project in school, but I'm having problems configuring the settings to make it work with Dev-C++. I'm using Webots...
Hi, sys/socket.h is not available with the cross-compiler as the Khepera BIOS doesn't support sockets. You should use some #ifdef statement in your code, like:...
Hi, The include files lies in the Webots/include and Webots/windows/include directories. Webots 3 uses libGtkController.lib (or libController.lib depending on ...
I would like to develop a system that will ultimately be used on a real Kephera robot. Is it possible to use Java, or does the cross-compiler require C? -- ...
... The cross-compiler requires C (and not C++!). I'd recommand you to check from time to time that your control program transfers well to the real robot, as...
... Yes, you are right. I initially thought you wanted to cross-compile and transfer the control to the robot to be able to unplug the robot from the PC. But...
I have written a controller that doesn't need a console window. How do I compile it so that it doesn't appear? -- Christopher Willmot Using M2, Opera's...
... If it's a C controller, simply remove the DOS_CONSOLE=1 statement in the Makefile. If it's a Java controller, then, I am not sure how to remove the ...
Hi, i am trying to do some computations with the noise values given in the differential wheel node. Can i verify the following, which is written in the...
Hi Danny, Yes, it is possible to simulate pan/tilt camera in Webots. In order to proceed, you should mount the Camera node on the top of two Servo nodes, one...
... This sounds correct. ... It is very similar to the slipNoise although a bit more complicated, if you set 0.1, then a noise of +/- 10 percent will be added...

Hello there, i have a problem with implementing a controller in Java, that has a thread to send sensor data to another pc. The whole static thing makes it...
Hello there, i have to come back to you once more. I have two different robots in my simulation. One of them behaves fine with all its sensors, but the other...
... Hi, I would recommand you to create your TCP server in a separate java Thread that can be instanciated from the main Controller static class. Here is a...
