This repository contains source codes for ALPHA Science AUV.

alpha_sci_auv Meta Package for ALPHA AUV.

alpha_sci_bringup Launch files for firing up the vehicle and simulator.

alpha_sci_config Configuration files for devices, vehicle controller, mission controller, and etc.

alpha_sci_description URDF descriptions, 3D Mesh, and launch files for the ALPHA AUV.

alpha_sci_stonefish Stonefish descriptions for ALPHA AUV.

alpha_sci_viz Contains configuration for RViZ.

Currently MVP packages should be build from the source. Target platform must be Ubuntu 20.04 because of the dependencies.
