High resolution black water imaging sonar
To locate drowning victims in poor to black water conditions the SARbot® is equipped with the Tritech Gemini 720i multibeam imaging sonar. The high resolution image and wide angle field of view make target acquisition quick and intuitive.
Specially designed limb grasping mechanism
A specially designed and feature patent pending grabber has been designed to grasp the limbs of drowning victims. Additionally, the ultra strong tether (100kg f working load) is cable of pulling the victim to the surface without risk of damage or breaking.
Battle hardened integrity
The SARbot® system are built on the industry leading LBV series of MiniROV systems. Designed and tested in cooperation with the UK Fire & Rescue the SARbot® has proven its capability and reliability.
Features and more features
Very fine detail and care has been implemented into the SARbot® system design. Little features like night time strobe, reflective tape, tool less adjustable grabber, electrical connectors all lend to the ease of setup, deployment and success. No other system offers the level of development as the SARbot®.
The theory behind the development of the SARbot® system was in response to the “golden hour” in rescue of drowning victims. UK Fire & Rescue came to SeaBotix in need of a solution to the more than 700 drowning’s that occur each year in the UK. Slightly unique to the UK is its dense population for such a small country and the fact that virtually all water is below 21ºC (69.8ºF).
Medical research and studies have proven that people can survive near drowning without permanent damage. Essentially the theory revolves around colder water rescues (less than 21ºC/69.8ºF) where the person is recovered from the water in under 60 minutes. Some have shown that the amount of time could reach 90 minutes. It does vary from person to person. The rescued victim is not resuscitated immediately, but over a period of approximately 48 hours.
Given that in many circumstances a rescue team can be onsite within 10-15 minutes of the person entering the water the obstacle becomes how to recover to the surface without putting rescue personnel in harm’s way. Many rescue teams are not permitted or trained as divers and therefore must look to technology for the solution.
A typical drowning in the UK is one where a person is intoxicated and enters the water unknowing its cold temperature. The shock of the cold water causes the person to inhale water until the lungs are full and thus the person drowning.
With most drowning victims found within 10-15 meters (30-50ft) of their last seen position the search area is quite small. The SARbot® system offers rapid setup (less than 4 minutes). Once deployed the SARbot® is flown along the surface to the approximate sighting. There it dives while viewing real time the video and high resolution imaging sonar on one big screen. As the SARbot® dives the operator rotates the unit to pan for hopeful acquisition of the drowning person. Once located the SARbot® travels to the victim until visual is possible where the limb grasping jaws are able to attach to the person.
Once attached the person is pulled to the surface with the incredibly strong tether where medical attention can begin. All this is possible without putting anyone in the water or in harm’s way. Simple to operate and setup by two persons.
To ensure operators are capable, initial training programs are conducted. For night time operations as many are there are simple yet useful features added. A blue strobe is fitted to the top of the SARbot® along with reflective tape. This allows the rescue personnel to see the SARbot® as it travels along the surface at night to the location.
