I am an engineer from the National Oceanography Centre and I have been working for a few years with UUV Simulator ROS1. It is about time we upgrade to ROS2.
I have looked at the following possibilities to ensure a smooth transition from ROS1 to ROS2 while keeping the same simulator architecture:
DAVE is built on ds_sim and we haven’t really done much development beyond those initial plugins that DAVE uses. So between ds_sim and DAVE I’d suggest DAVE for broader community support and activity.
The migration is maybe more helpfully discussed here.
