Hi all. I want to control virtual kphera robot with my microcontroller. (I use serial port).Controller sends '1'to serial port but webots can not see it.I have...
Thanks for your detailed answer, Yvan. The reason that I want to run Subsumption Architecture with threads is that I am modelling a real autonomous vehicle and...
Hi guys, I'm new here and I would like to ask you a little question. I'm working on a project with a small robot, whose goal is to find a lightspot in a Room...
I want to call Webot methods from Java classes but can't figure out how to do it. I have tried controller.setSpeed(1,1); but that doesn't work. Which object do...
Hi Sridhar, It's not possible to pause the simulator from a supervisor. Alternatively, the supervisor could send messages to the controllers in order to let...
Hi Colin, We designed the object-oriented API to be used like this: * extend the Robot class (or one of its subclass such as Supervisor and DifferentialWheels)...
Hi Benjamin, I looked through your code. The problem comes from the line 246 and 247 (and also 275 and 276) of the world file which must be removed: DEF...
That file which I posted yesterday was my first version of the robot. This one: "zlug.org/~bebl/webots.tar.gz", is a newer version with little more details,...
Hi Shawn, In memory, this occurs when you are trying to import a VRML node either from the Webots GUI or from the supervisor API, and the format of the vrml...
omg, these four lines of code made that big mess. After I've removed the second grouping from the body (I rly don't know why I made a second one..) the whole...
Hello, I recall this kind of error with older versions of Webots. I used to solve the problem by manually redoing the end-of-line right after the "#VRML V2.0...
Hello Colin, ... The stderr and stdout streams from the controller process are redirected to Webots and printed in Webots console. However, we have had several...
Hi, From what I understood, you have a real micro-controller outside the computer sending serial commands to the computer, right? In such a case, you should...
I opened one of the webots .wrl files in notepad and did not see below mentioned end of line. Would you have a test .wrl file to try and or look at? The...
Hello Shawn, ... Yes please send us your .wrl file using Webots menu: Help->Bug Report... ... It does: Webots files are .wbt files and as far I know Webots can...
I am developing a Subsumtion Architecture based on the LeJos classes. I need to have classes like the following:- public class DriveForward implements Behavior...
The file is uploaded to the bug report..... On Tue, May 5, 2009 at 11:17 AM, Yvan Bourquin < ... -- "They say the best weapon is one you never have to fire,"...
It seems that you doesn't have declared a variable controller, which at least, instantiates DifferentialWheels. At least I can't see any in the code, that...
Thanks for your observation, Ben I have my controller set up correctly like :- (public class MyController extends DifferentialWheels { I want to be able to use...
Hi Colin, The setSpeed() function is inherited from DifferentialWheels and so it is also accessible as a public function of MyController. So, setSpeed() can be...
Actually, this dialog message is displayed when the .class having the same name as the directory (for example: controllers/ControllerName/ControllerName.class)...
Hi, I'd like to run multiple simulations at the time, so I'm looking to use several machines at the time to do this. I found that when I run the same...
Hello Matt, Yes, in Fast mode the graphics card difference should vanish. Does your simulation use Camera devices ? The Camera rendering is also done with...
Hi Yvan, No, I don't use Camera devices. And yes, they are both really doing the same thing. It's very simple for now, just a bunch of robots running around in...
Hello Matt, Maybe another partial explanation: Besides the similar frequencies, your faster machine has two CPU cores while the slower machine has only one CPU...
