Thanks to everyone for filling out the Gazebo survey, and helping direct our development plans. We have received 260 responses from simulation users around the world. The following is a summary of the survey results.
The core content of the survey listed a set of potential features for simulation. Survey participants ranked each feature from one to six, where one is low desire and six high desire. The following graph shows each feature on the x-axis, and the sum of the votes the feature received.
Physics validation has achieved a clear first place position. Throughout its history, Gazebo has aimed to mimic reality as closely as possible in order to offer simulation as a useful development and testing tool. The addition of physics validation will quantitatively ground the accuracy of Gazebo, and help guide the use of simulation. While difficult to accomplish, we also view Physics Validation as a high priority. Stay tuned for more updates on this effort.
Following in second through fourth place are Real-world sensor visualization, CAD import utility, and a graphical model editor. We will lump in the highly rated plotting and improved logging features to form a category about usability. Gazebo has not been known as a tool with a great user experience, and ability to easily import models and retrieve data. Fortunately, this is all about to change. Under active development is a graphical model editor that will simplify the process of creating new robots and objects, a plotting utility, and improved state logging and replay capabilities. Over this summer we will also kick-off a project to facilitate importing CAD models. Most of these features will likely land in Gazebo 4.0, scheduled for a release in fall of 2014.
For those of you keen on features that have not been discussed yet, fear not, they will be developed and integrated into Gazebo. The timeline for these features is a bit more fuzzy, but I can say that most everything on this list will be done or started in less than 1.5 years from now. If you would like to see something accomplished sooner rather than later, please speak up and ideally come prepared to offer some of your time. Send a message to our mailing list, and describe what project you would like to be part of.
We received a lot of great comments, feedback, and perspectives from everyone. The following is a brief list, broken into categories, of the feedback, in black, and our responses to the feedback, in blue.
Thanks again to everyone for their help and support. We look forward to a productive year, and keep the ideas and feedback coming!
