Hello,

I installed Gazebo 7 and then downloaded models from https://bitbucket.org/osrf/gazebo_mod... placed them inside ~/.gazebo/models/ (because gazebo refuses to automatically download any models).

Many of the models work just fine but there is a group of them that refuses to be placed in a world and will in result crash gazebo. In the gazebo log it looks like this:

2017-12-04 01:27:14 -0500 marked best answer Gazebo - How to manually input coordinates of objects

Hello,

Im using gazebo 2.2 (ubuntu 14 trustly with ROS indigo). I created my world with a TurtleBot robot inside for simulation purposes.

Now what I'm looking for is a way to manually input initial coordinates of objects. I want to select an object, for example said Turtlebot (mobile_base) and then place it exactly at X = 1.5, Y = 1.5, Z = 0 and then give it rotation yaw = -1

How do i do it?

When i select world object mobile_base it has "pose" property that can be edited but i cant see a way to save these new values, each time i click outisde of the world tab, they reset to previous values.
