well, since i am working with gazebo 7 and ros kinetic i am not to able to use the level feature in this operational environment so i used a different approach: i load the mesh with several collisions and enable the tag <collide without contact>1</collide without contact> to avoid gazebo to perform collision computation and thus increasing the

without you i'm just a fraction closing in on my demise and i love you religiously with everything inside of me as long as i'm as long as i'm alive when we collide-ide-ide when we collide, it's a beautiful disaster when i crash into you, you, you crash into you, you, you when we collide-ide-ide when we collide, it's a beautiful disaster

who wants to build a robot? robots can be expensive, time consuming and challenging to get right. for those of us who want to focus on the software systems without having to build a robot, there are simulators available that can help with development. this post will describe how you can get started with gazebo and ros to experiment with robotic software.
fuerte gazebo 1.6.16 hi all, i've been fiddling for a long time, trying to control a model in gazebo. after tweaking the ode settings and setting controller parameters to zero, i think i've found the underlying problem: my simulation has no friction or self collision. the robot spawns in this position: and should just sit there under the influence of gravity.
contact forces are the result of solid bodies interacting with each other. to approximate contact behavior in simulation, we use contact models. the two main components of contact forces can be broken down into. normal forces: push objects away from each other when they collide. as their name suggests, these forces are normal to the point s of
i have a similar problem: i have a player character snowboarder who is moved by my code, i don't want the physics engine to mess with. on the other hand, when he touches the fence of the track, i would like to know where he touched it. hence i would like to use oncollisionenter and not ontriggerenter because the former has information about the collision points whereas the latter only
the sdf version shown in the dropdown above defines the specification version. this version number may be different from the release version of libsdformat, which contains the c library used to parse sdf files.

a collision is the event in which two or more bodies exert forces on each other in about a relatively short time. although the most common use of the word collision refers to incidents in which two or more objects collide with great force, the scientific use of the term implies nothing about the magnitude of the force.
this gazebo is made with fabric that meets cpai-84 specifications for flame resistance. it is not fire proof. the fabric will burn if left in continuous contact with any flame source. the application of any foreign substance to the gazebo fabric may render the flame-resistant properties ineffective. >>assembly instructions

i am a beginner in ros and rviz i would like to get kinect module work with ur5 simulation. right now i installed ur5 library from universal robot. after that i installed openni kinect kinetic version on my ubuntu 16.04.
another comment: in the heightmaps test file there are a few tests which currently cause a segfault after all the gtest tests have been run crash on exit , i haven't investigated why this is. it is not related to the changes in this pr, but it may be related to having dart support enabled in gazebo, the crash backtrace came from libdartd.so.
there are magnificent tutorials about how to create plugins for gazebo in the gazebosim webpage. there are even some tutorials about how to create plugins for gazebo ros.those tutorials show that there are several types of plugins world, model, sensor, system, visual , and indicate how to create a plugin for a world type plugin.. recently i need to create a plugin for a light detector.
tutorial: using a urdf in gazebo. the universal robotic description format urdf is an xml file format used in ros to describe all elements of a robot. to use a urdf file in gazebo, some additional simulation-specific tags must be added to work properly with gazebo.
i have a model that i consists of a shelf and some boxes in it. i made this model on other programs like blender or google sketchup and imported on gazebo as collada file. i'm facing two issue on the gazebo model: on importing the collada file from any other software no texture is applied. the figure shows the collision of my model. that is correct.
