Ocean Worlds Autonomy Testbed for Exploration Research & Simulation (OceanWATERS)

Overview | Release Notes | Getting Started | Contributing | License

Overview

OceanWATERS is a ROS-based physical and visual simulation of a lander on the Jovian moon Europa. It is intended as a testbed to aid in producing software that could help enable autonomous lander operations on ocean worlds of the Solar System, such as Europa and Enceladus.

See the project wiki for full documentation.

See the Release Notes for a list of feature enhancements in the latest software release.

Code Organization

The ow_simulator is the top level repository for OceanWATERS. It primarily contains ROS/Gazebo packages related to visual and physical simulation for OceanWATERS. It also contains workspace files for setting up the rest of the OceanWATERS repositories:
