Hi eveyone, Is it possible to change the camera width and height properties online from the robot controller? The function camera_set_fov seems to be...

Hi guys, I've got a very simple question here. Hope that you guys will help out. I've used the wizard tool to create a new robot controller, and I choose C as...
Some more question that I've found. Sometimes it displays this message for me: mingw32-make mingw32-make: *** No rule to make target `my_controller.o', needed...

Hello, I think, that you just need to hit "Clean" to get rid of the "trial.d" file. Also be careful with the source file name and the directory name. Webots...
Thanks for the help Yvan. It really helps and I appreciate it. However, I still can't get the ".exe" file. Here's what I've got so far. I started a new...
I used Matlab to do a simulation experiment. The experiment was very successful. But when I used webots to do the same simulation experiment. The problem was...
hi everyone, i am trying to use the same neural controller (same executable) to control 2 different robots in a different way. basically, the controller starts...
Hi Stevie, Having two instances of the same controller to control the two robots should make no difference from having two different controllers with identical...
Hi Olivier, By "undefined results" what I meant was that when I have the robots connected together and running their own instance of the same controller ...
Hi, We just released Webots 6.0.0. You can download it from the usual place: http://www.cyberbotics.com/products/webots/download.html Any Webots 5 user with a...
Hi All, We currently use Webots 5.9 together with e-puck robots. By the API 'differential_wheels_set_speed', we can set the speed for e-puck robots in both...
Hi, Indeed, the Webots API has not a 'differential_wheels_get_speed'-like function because this feature is not realistic for the major part of the real robots....
hi Fabien, "The e-puck has no encoders but it can count the steps applied on its stepper motors." does this mean that the e-puck has some sort of encoder on...
Hi Stevie, For being clear: an e-puck has no encoder. But there is a trick for knowing how much steps the motors should have performed. This doesn't returns a...
hi Fabien, thanks for clearing that up for me. cheers stevie ... From: webots-users@yahoogroups.com on behalf of fabien.rohrer Sent: Fri 19/12/2008 09:26 To:...
Hi Fabien, Thank you for your reply. so, you mean, the encoder or steps from stepper-motor become inaccurate if slippage happens during motion? As for...
... Hi, ... Yes, they do. It is the case for every encoder which measures the rotation of a wheel. ... You are right, the robot obviously takes time for...
Thank you Fabien, But is there any way of compute or measure each actual time-step at remote control of e-puck? We run some test on both simulation and remote...
... Unfortunately, nothing is implemented for this kind of measure. ... This is true but using only the encoders is often enough to estimate the position at a...
Thank you Fabien, The codes worked well. we are trying to use clock() function in C to calculate the interval between time steps. But if e-puck works on remote...
I don't know what will be your application but I think measuring time is not necessary for computing the odometry of the e-puck (cf. the example I sent you). ...
Hi what does rotate mean in webots? what is formula? sqr(cos(a))+sqr(cos(b))+sqr(cos(c))=1 ? webots tell in rotate x [m] y [m] z [m] alfa [rad] what are...
Hi, I'm not sure I understood your question ... Do you mean: what are the "rotation" fields in Webots ? The "rotation" fields use the Euler axis/angle...
