i am new to gazebo and for my application i would need to add several dynamic models, the state of which influences the robot models present in the world. a simple example could be a time varying wind model that needs to be accessed from within the robot models in order to compute aerodynamic forces. from the gazebo documentation i was not able to work out what is the best way to implement
for sg, just type roslaunch diff drive gazebo main.launch on a terminal to open the empty world in gazebo. then open your preferred editor to create the model files as described below. then open your preferred editor to create the model files as described below.
adding model from the model database. gazebo's model database is a repository of all types of models including robots, tables, and building. select the insert tab in the upper left hand corner to access the model database. the list of models are divided into sections according to their current location. each section is labeled with a path or uri.
building a model step 1: collect your meshes. this step involves gathering all the necessary 3d mesh files that are required to build your model. gazebo provides a set of simple shapes: box, sphere, and cylinder. if your model needs something more complex, then continue reading. meshes come from a number of places.
the model.config file is used to tell gazebo about a model. make sure that you have a model.config in your model directory. also make sure that the model.config refers to the correct sdf file, which should exist in the same directory as the model.config file.
textures map an image onto a shape. they add detail to a model without adding geometry. the color added by a texture is made visible by both ambient and diffuse light. setting the texture of an object ogre material scripts. ogre material scripts have many options for applying a texture to an object. read the ogre documentation for more information. collada
overview. note: you don't need to add your model to the database in order to use it in gazebo. the database is a common place where you can find models which are useful for the whole community. note: make sure that you have permission to distribute all the files included in the model and they're not copywrited material.
next we must define the gazebo plugin that gives us the laser range finder functionality and publishes the laser scans to a ros message. add the following code to your turtlebot gazebo.urdf.xacro after the </xacro:macro> tag closing the kinect macro.
as a person who is new to gazebo and even ubuntu i have some basic questions. i wanted to open a solidworks created model in gazebo. according to information that i received from solidworks sources, i downloaded sw2urdf add-in and used it to create a urdf file. unfortunately i've got mixed information about opening a model in gazebo, i don't even know which format is the correct one: urdf
alternatively, start from a fresh gazebo instance. insert a model from the insert tab on the left. for example, let's insert a simple arm. right click on the model you just inserted and select edit model. now you are in the model editor and you are free to add new links to the model or edit existing ones.
hello i am very new to using things like gazebo and ros. i was wondering about how one might take a model from gazebo like turtlebot or quadrotor and attach a camera to it, and see the feed? my guess is that i have to go into the code of the model files and add camera code? but i am unfamiliar with the code or how it works. and how would i get the feed?
probably there is also a simply gazebo way to do this, e.g. add a joint to your model and use the built-in tools to set the joint's velocity. however, i never did that and hence can't provide much information about it.
you should read all of these tutorials to get a firm grasp on how to communicate between ros and gazebo. when you add multiple models of the same name into gazebo, their names will be appended with numbers. this gives you the ability to address an individual model. in other words, it changes the topic name or contents of the messages to gazebo.
be sure you upgrade to a version of gazebo which is currently supported, that's either gazebo 7 or 8. then you could do it like this: insert a simple shape into simulation. right-click -> edit model. double click -> open the visual tab. expand visual. under geometry, type in the desired values. repeat 3 5 for collision. file-> exit model editor. save and exit
'how to add light sources in the gazebo world dynamically ?' i am using ros-groovy gazebo 1.5.0 . in electric pre-1.0 sdf there was this <model:renderable> option where i was able to spawn light source as a model after launch the gazebo world in any pose i wanted.
typically, there are 3 methods to let gazebo software load a model as mentioned in this answer. export gazebo model path properly. if gazebo doesn't start at all, then setup gazebo and environment variables and then export gazebo model path move the models to 'gazebo/models' folder directly and include the uri in launch file.

</description> </model> adding the directory and files to the repository. you can add all of your files to the repository by typing the following from the root directory of gazebo models: hg add mymodel or, if you have some files that you do not wish to track, you can add files individually: hg add mymodel/model.config hg add mymodel/model.sdf etc.

above code is how you would add a differential drive gazebo plugin to the robot model. any plugin within <plugin> tags must be included under <gazebo> tags. filename is the gazebo ros. library name containing the plugin implementation.

hello, i am trying to make text recognition using an asus camera. i manage to have some results by using tesseract and extract script and created a script combining them. now i am trying to simulate it with a turtlebot in gazebo but i dont know how to add a model that has something written on it like a sign that writes stop.. is there a way to add my own model with text on it or just 2d images?
