[ros-users] other than gazebo ?

Sorry I have lots of question ;) What kind of robots are you thinking of
using? what types of environments, sensors, actuation/dynamics and what
level of fidelity do you need to capture in your exercise (simulation)?
On the sensory simulation side, since you mentioned 3D, I am guessing you
want to model rgb images and point clouds from depth sensors?
With regards to world environments, do you anticipate having a "simple"
world with perfectly flat terrains and box shaped obstacles, or more complex
world with hills, valleys, caves and tunnels with realistically textured
On the dynamics side, if f=ma is not terribly important to you, one
possibility is to disable physics computation/updates in gazebo, write a
plugin to "warp" your "bug"'s 3D poses based on some simplified heuristics
and reuse the range and image sensor generation capabilities as implemented.
On the other hand, please let me know if you something in the current gazebo
implementation is prohibiting you from making use of it in your project.
For example, most people probably do not enjoy editing XML robot model
