The New Generation REMUS 100 marine robot features advanced technology and capabilities that are the first of their kind in the industry, enabling customers to have increased autonomy and creativity during their missions.

Adaptable and reliable

The REMUS 100 AUV can be configured to include a wide variety of standard and / or customer specified sensors and system options to meet your unique autonomous mission requirements.

Over the past several years, the REMUS 100 AUV has become the cornerstone of the coastal AUV market, with thousands of missions, and tens of thousands of mission hours to its credit. No other AUV system comes close to rivalling REMUS' proven track record for system quality and dependability.


The capabilities of the REMUS 100 make it ideally suitable for marine research, defence, hydrographic and offshore/energy markets. The vehicle is small enough to be carried by two people, yet contains enough sophisticated sensor, navigation, and power resources to enable it to perform intricate sonar and oceanographic surveys over large areas.

Compact size & weight

  • The Perfect Balance of Design & Technology. The reimagined new generation REMUS 100 is designed and built with the latest technology while maintaining the performance and engineering quality our customers have come to expect from our AUVs.

Auxiliary Equipment

Health Monitoring

All HYDROID AUVs have core systems designed to monitor the status and operation of essential components. Health monitoring includes batteries, motors, sensors and communications as well as conditions such as depth or water ingress. If an abnormality is detected, then an alarm is raised. During supervised missions this will be transmitted to the operator enabling them to decide if the vehicle should return from its mission. When the vehicle is operating autonomously, the response to an alarm is determined by the preselected response listed in the mission plan. This could include an emergency abort to preserve vehicle security.

Communication and Tracking

Operators can monitor the AUV's progress and status via an acoustic link. This also enables amendments to the mission plan to be sent to the vehicle along with position updates if required. The HiPAP (KONGSBERG acoustic underwater positioning and navigation system) or Ranger positioning systems provide acoustic aiding to the on-board IMU (Inertial Measurement Unit) and DVL (Doppler Velocity Log) equipment to make the real-time position solution as accurate as possible. Some HYDROID AUVs also transmit real-time side-scan and bathymetry data back to the operator acoustically. This data is displayed on the payload computer screen to give the operations team confidence that the mission is progressing as planned and there are no gaps in the data. When the AUVs are on the surface, they can communicate via Wi-Fi or radio with the operator. They are also equipped with GPS receivers to update the IMU position with the most accurate information available.

Emergency Localisation

To assist with emergency localisation and recovery operations, the AUVs can be equipped with emergency radio beacons, strobe lights and satellite communications. In the event of an emergency ascent, the position and status of the vehicle can be sent via the Iridium network to the operators and home base simplifying post-emergency localisation. If two-way satellite communication is enabled, a revised mission plan can be sent to the vehicle from anywhere in the world.
