Imotus-1 AUV

Overview

 OLYMPUS DIGITAL CAMERA

About Imotus-1

Imotus-1 is built on a modular core platform, using ROS over Ethernet to communicate between the navigation sensors, main computer and payload modules.  Proprietary Simultaneous Localization and Mapping (SLAM) algorithms have been developed to enable navigation, station keeping, route following and autonomous operation in a variety of confined space environments.

The vehicle can operate with or without a fiberoptic umbilical and can dock underwater for recharging, mission data downloads and task updates.

    The Following organizations use and Trust the Imotus-1:

    Design Highlights

    Snag Resistant Design

    Imotus-1 is designed to be snag resistant for use in complex enclosed spaces. If the optional fiberoptic tether becomes snagged, it can be cut at the vehicle.  A safe route to the extraction point is then autonomously followed.

    subsea charging and data transfer

    An optional docking station allows Imotus-1 to be permanently deployed at the work site.  Inductive power transfer allows recharging when docked and a blue-light modem provides real-time, high bandwidth communications.

    Accurate corrosion Monitoring

    An integrated ultrasonic thickness gauge allows Imotus-1 to take detailed measurements of steel pipes and walls, autonomously generating corrosion maps of the survey targets.

    Benefits

    SLAM Navigation

    No prior knowledge is required to operate in confined spaces.  Imotus-1 can map the workspace and navigate within it.

    6 DOF

    Eight vectored thrusters provide full 6 DOF maneuvering with redundancy.

    Real-time Feedback

    An optional fiber optic umbilical allows real-time, high bandwidth monitoring of vehicle health and sensors, including inspection cameras.

    Low Logistics Platform

    Imotus-1 has a fully portable launch & recovery system and monitoring interface system for easy mobilization.
