Hi, It looks like this is a bug in the libController of Webots. Could you send me (to me personally, not to all the list of Webots users) a very simple sample...
... That sounds a nice way to approach the problem. An alternative would be that instead of implementing a bi-directional communication system where the robot...
Hi, This should work... Are you sure the greenRobot is correct. It should not be NULL. You can test it with the supervisor_node_was_found() function. An...
hi in the khepera2 model, the maxSpeed value is set at 100. the real robot has a max speed of 0.5m/sec. the value of 100 would equate to a maximum forward...

thank you. how can avoid the robot to create a shadow? i need only obstacles-shadows. is it possible to choose which objects will create a shadow and which one...
Ok, after a more careful search, I've found Yvan's reply to a very similar message. I'll try the physics plugin trick. Sorry for the unnecessary question. ...

Hi, My lab has a robot using omni wheel, and wanna create a simulation by webots, but I didn't have a good idea to bulid a omni wheel model. please do me a...
Hi, ... I believe some Webots users implemented omni wheel robots. This can be achieved using a CustomRobot node and putting your own wheel system using...
Hello, Unfortunately, the shadows can only turned on/off for a specific light (DirectionalLight or PointLight). There is no way to turn them on/off for a...
Hello Joanne, I tried this out, also with Java and I found out that the controller does actually get changed ! The mistake is to expect that something will...
Hi, ... There should be not special effect or disadvantage of doing this. Just take care that if the robot controller communicates with the supervisor ...
