2015-10-17 04:17:01 -0600 | asked a question | How can I control a simple model using the keyboard? Good day. I want to make a plugin which allows me to control a simple model (a sphere, for example) using the keyboard (like w,a,s,d keys), but I don't know what functions or methods I need to use in the .cc file. Can anyone answer me with a simple tutorial about this problem? Thanks a lot. PS: I want to solve this problem without using ROS. |

2015-09-24 13:43:03 -0600 | commented question | Problems extruding svg files in Gazebo (2) Thanks, chapulina. How can I add these questions in the reopened questions? Do I have to click on "Answer Your Own Question" button or something like that? |
2015-09-24 12:35:34 -0600 | asked a question | Problems extruding svg files in Gazebo (2) Good day. Thank you, nkoening and hugomatic, for answering my questions in the previous question thread I closed accidentally. I finally get my chassis import, but I've got more problems:
Qt has caught an exception thrown from an event handler. Throwing exceptions from an event handler is not supported in Qt. You must reimplement QApplication::notify() and catch all exceptions there. terminate called after throwing an instance of 'Ogre::InvalidParametersException' what(): OGRE EXCEPTION(2:InvalidParametersException): Object index out of bounds. in SceneNode::getAttachedObject at /build/buildd/ogre-1.8-1.8.1+dfsg/OgreMain/src/OgreSceneNode.cpp (line 160) Thank you in advance. |

2015-09-23 04:56:08 -0600 | asked a question | Problems extruding svg files in Gazebo Good day, Gazebo people. I'm a Gazebo beginner. I started using Gazebo less than two weeks ago and I've been reading Gazebo's tutorials, but I don't understand this problem: When I try to import a svg file that I created with Inkscape, a message appears: Invalid file No paths found on file "/home/user/Desktop/my_chassis.svg" Please select another file. I don't know why this message appears, because the 2D chassis I created and the 2D tutorial chassis are very similar. I don't know if I'm doing something wrong. Here is the simple 2D chassis I've created: Another problem I have is that I successfully import my 2D wheel, but the program goes crazy. Here is my 2D wheel and here is the Gazebo's extrude link window As you can see, it has no similitude with original picture. I clicked the Ok button, but this message about render engine OGRE appears: Qt has caught an exception thrown from an event handler. Throwing exceptions from an event handler is not supported in Qt. You must reimplement QApplication::notify() and catch all exceptions there. terminate called after throwing an instance of 'Ogre::InvalidParametersException' what(): OGRE EXCEPTION(2:InvalidParametersException): Object index out of bounds. in SceneNode::getAttachedObject at /build/buildd/ogre-1.8-1.8.1+dfsg/OgreMain/src/OgreSceneNode.cpp (line 160) I hope you can help me with these problems.
