Dear Hamid, In response to your questions: 1. The fast button at the top of the screen is one way to run webots in fast mode. Another way is to start webots in...
Hi all, I'm currently trying to model a quite complicated robot for pipeline inspection. The Robot has three sets of levers that are arranged starlike around...
Hi, Adjusting the parameters of the physics simulation is complex particularly for simulations having loops, mainly because all the physics parameters are ...
Hi Fabien It works fine now, it was a matter of going through the specification again. Sensors read the values at distance ranging from 0-80 cm, using at 50...
Dear Hamid, 1. Again whether this can be accomplished depends very much on your implementation. For my own simulation with 50 objects and 10 DifferentialWheels...
Some comments. I've run similar optimizations with the HOAP-2, and yes, they will take time. I've had optimizations running for over 10 days on 40 machines. If...

HI guys i got problem with cross compiling file into hex file. how do i cross compile where the option for it could not be selected. Thanks...
Hi, The controller directory must contain a file named "Makefile.e-puck" (for the e-puck) in order to enable the cross-compilation menu items in the Webots...
Hello Hamid, 1- As you know, to run the evolutionary algorithms the software should run in a very fast mode, the only supported feature I found was the fast...
Dear all, I'm coming back to the group with a new question! I've build an articulated snake robot, a robot consisting of 12 segments, just like a real snake...
I have view the controller of the e-puck line demo. But i still do not understand what should i put in order to make the e-puck out of the line when it detect...
Hi, Normally, the comments in the source code and the pdf distributed in the e-puck_line folder should be sufficient to finalize this controller and get the...
Hello Yuanlin Vega Liu, Note that some sensors are "noisy" in there default configuration. This is the case of the GPS which has a "resolution" fields that...
Hi,I am learning to cross compile and to view the examples of how the e puck works But I face the the following errors after cross compiling the e-puck...
Hi, Normally, this bug has been fixed since Webots 6.1.4. It was due the a missing library in the e-puck library. Installing the last Webots version (6.1.5)...
Hi, I was converting some code written in webots5 to webots6. the code invole two method gps_get_matrix() and gps_euler(). From the file giving online said...

Hi Yongjin, First of all, *wb_supervisor_get_sf_rotation* (documented ...
Thank you for the help. according to what you said, i need to computed the euler matrix by myself. could any one tell me what is euler matrix and how to...

Hello Yongjin, What you guys call a "euler matrix" is actually a "rotation matrix" or "DCM matrix" (Direction Cosine Matrix). See there. ...
Hello, I am curious about how does servo really work... For example, if I have a robot lifting left leg to the front at initial state and in controller, I use...
Hello, ... Just like a real motor, the Servo works by applying a torque to a axis. Indeed, calling wb_servo_set_motor_force(joint[2], 0) turns off the motor...
Hi all, I'm currently programming webots with Java, unfortunately the webots provide us with a poor java documentation so I want to see whether any one has...
Hi, I agree, this is still not very well documented... The supervisor API reflects the scene tree. Generally speaking, in order to get or to set a value, you...
Hi guys: My problem is this: I am trying to control a biped robot in Webots. Part of my control strategy invovles doing calculations that uses joint position...
Hi Henry, It's unfortunately not possible to remove completely the noise you get because it is due to the physics engine of Webots. Effectively, like in the ...
Hello, There is nothing so close to a suction actuator in Webots ... However there may be two different ways to achieve what you seek: 1. Use Connector devices...
