The ROAZ Autonomous Surface Vehicle is an small aquatic autonomous surface craft designed for river and estuarine operation.

The robot was developed by LSA - ISEP, to perform environment monitoring missions, bathymetry and support multiple vehicle operations (either submarine autonomous vehicles, aerial autonomous vehicles or surface autonomous vehicles).

The vehicle can carry multiple application sensors, ranging from bathymetric sonars, sidescan sonars, CTDs, water samplers etc.

A twin hull configuration was implemented in order to allow suitable AUV docking capabilities (by convenient use of inter-hull space) and to reduce volume. The vehicle was developed in fibreglass structure reducing weight.

The vehicle has relatively low area exposure above water with all the electronics in the bridge section between hulls, thus reducing wind effects. It has a flat top surface allowing solar panel coverage and depending on vehicle configuration can support a camera tripod or a communications mast.
The central section has structural fixation points underneath and a connectors access for application of different types of sensors and mobile AUV dock mechanism.
A payload up to 50 kg can be added. Battery support and fixation is provided inside the hulls.
A bottom sealed hatch in the central section can be configured with different plugs and connectors according with the sensor suite used.
The vehicle overall dimensions are 1.5x1x0.52m, and the hulls were designed in order to reduce hydrodynamic drag.
