Imotus-1 AUV



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.


SLAM Navigation

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


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.
