[ros-users] [Discourse.ros.org] [Autoware/Autoware Simulator Project] Simulation software requirements

[Geoffrey Biggs via Discourse.ros.org]

@bshin-lge I'd like a plan for simulation support and usage to be put together. Every simulator has its strengths and weaknesses, and that is not going to change no matter how much one simulator tries. It's not just a question of features but also of underlying technologies used, how features are implemented, etc. So we need to understand what each simulator is best at and where it can be best applied. For example, if I were making a demonstration video, I would probably use LG's simulator. If I were doing simulated cameras, Cognata's simulator produces images that are more photorealistic. If I were doing statistical data gathering of planning performance across a range of scenarios, I would also probably use Cognata's because they have a good system for  generating scenarios procedurally and deterministically, and executing them deterministically. LG's simulator and Carla appear to have better physics simulation and so are good for control testing. Things like this need to b
 e considered and each simulator developer needs to decide on what sort of usage they wants to focus on. Then we can decide how to apply each one.
