  The number of tools for dynamics simulation has grown in the last years. It
is necessary for the robotics community to have elements to ponder which of the
available tools is the best for their research. As a complement to an objective
and quantitative comparison, difficult to obtain since not all the tools are
open-source, an element of evaluation is user feedback. With this goal in mind,
we created an online survey about the use of dynamical simulation in robotics.
This paper reports the analysis of the participants' answers and a descriptive
information fiche for the most relevant tools. We believe this report will be
helpful for roboticists to choose the best simulation tool for their
researches.
