Hello, is there a simple way to move (pan/tilt) a camera mounted on a robot? i.e. to change the "rotation" fields? I mean by the robot controller, not from the...
Dear Webots friends, Does anyone know how to model a water environment in the salamandar demonstration which only has a dll file without source code? Any...
Hello Claudio, You can pan/tilt a Camera by putting it under the control of two Servos. (One Servo for pan and another one for tilt.) Here is a VRML example...
Hello Hiroshi, This is quite complex ! You need to know a bit of physics, of vector maths, and of ODE programming. You will have to create a physics plugin for...
Hi, can I set a robot's position to a given (x,y,z,roll,pith,yaw) at run-time? I can do that using the supervisor, but I would like to do it with the robot's...
Hi all, i have made a function that moves the head of the my robot (Aibo). If i use the function inside my controller (controller.cc) works, but if i put it in...
hi everyone i am having some troble with my controller. it is a neural controller with recurrent connections. when i run it after a while the controller stops...
hi stevie, ... you did not mention where these values are generated! but i guess you get them from gps_euler, right? in that case your robot probably gets into...
hi stevie, ... you did not mention where these values are generated! but i guess you get them from gps_euler, right? in that case your robot probably gets into...
hi hannes sorry i did not explain properly but i am not using gps_euler. i am using a neural network to directly control the robot. the weights i load from a...
hi stevie, in that case i have no idea. i know this type of error only from invalid divisions. i would try to add an alert to get informed when the denominator...
just a quick question if a robot has both an emitter and a receiver both set to channel 0 and a supervisor has the same configuration. when tryin to...
Hi, You probably don't need any more include file. Please double check that your servo_set_position() function is called within the control loop (inside the...
... Yes. ... Generally, you should avoid having several emitters set on the same channel. This may cause undefined results in the messages produced. Also, if...
Hi I've written a controller using a pioneer and a camera which uses the images from the camera for obstacle avoidance. Unfortunately my world isn't great. It...
hi there! has anyone experience with creating profiles from a controller run? i would like to have a performance analysis, but as webots creates the controller...
Webots 1.0 was running on Sun. That was a long time ago. We ported some later versions of Webots to Sun (and also to Irix) upon customer request and payment...
Hello, another newby question: is it possible to draw the trajectory of a flying robot? I know it is possible for wheeled robots with the "pen" tool of a...
Another newby question: can nodes be created at-runtime? E.g. boxes, spheres or shapes? Thanks again -- Claudio ... Claudio Rossi "Ramon y Cajal" research...
Hi guys, We are interested in hooking out webot up to a large controller system which runs as a separate OS process. I'm worried about concurrency issues ...
... Yes, this is possible through the use of the physics shared library. This plugin architecture allows you to draw anything in the Webots scene using...
I'm trying to add a pannel that comes up and displays information from the world like some of the default worlds like khepera_gripper.wbt But I can't see how...
... Hello Olivier, a copuple more questions 1) can drawings be made only by the "physics" pugin? I tried to call open GL functions from the the robots'...
Hi, there is a mistake in the sample code I attached... here is the correct one: ... robot_geom2 = dWebotsGetGeomFromDEF("HELI2"); // OK, valid pointer...
I want my controller program to read and apply direct physics forces rather than use the servo API. However direct forces need to be done in a separate ...
