The lifeguard robot will detect the actions related to the drowning person, find the location, carry out the rescue, anchor the corpse on the platform and float it to the surface.Everything in record time
From the research team Fraunhofer Institute for Optoelectronics, The imaging system and development technology IOSB from Ilmenau, Germany has developed an underwater vehicle that can be used for underwater rescue in emergency situations. It is suitable for swimming pool rescue.
How do you detect that there is a danger?
“When a person is drowning, the typical posture makes the robot aware of danger,” said project manager Helge Renkewitz.
The robot does not act alone. The surveillance camera must be installed around the swimming pool (if it is an indoor swimming pool, it should be installed on the roof). The camera records the movement and position of the person submerged in the swimming pool and sends the coordinates to the robot.
Store the robot safely in a station on the floor of the swimming pool. The station will not be pryed apart and the station will open in an emergency. After the vehicle reaches its destination, it will find the person in distress and bring it to the ground.
Even if the victim has been killed, the anchoring device will lock it in place to prevent slipping.
Open water test
The robot has been tested in German lakes. The researchers’ suggestion is to place the camera in the covered swimming pool on the roof and install it on the surveillance drone in an open area. Renkewitz said: “These can be easily equipped with cameras.”
For lake rescues where visibility is restricted, underwater vehicles must be equipped with acoustic sensors instead of optical sensors. The echo of the sound wave can be used to determine the position and direction of the person, so that the robot can automatically orient itself to the target person and pick it up.
An 80 kg model was placed at a depth of three meters. Then, the robot picked it up, fixed it in place, took it to the ground within one second, and transported it to the shore where the rescue team was already waiting in the shortest distance (40 meters).
When the robot was notified of an emergency, the signal immediately warned the team. The entire rescue operation lasted only two minutes.This
The design of the robot in the future will be the design of the manta
The system is equipped with batteries, motors, cameras, and optical and navigation sensors, and measures 90 cm in length, 50 cm in height and 50 cm in width. The goal of the Renkewitz team is to further reduce the size of the rescue system and build different versions for swimming pools and lakes. Their goal is to make it smaller, lighter, and more cost-effective than existing prototypes, which are based on existing underwater vehicles. On the contrary, future robots will have a simplified design of stingray.
The water robot has applied for a patent. In the improved version, it can perform other tasks, such as sea and dam wall inspections, or used to monitor the health of fish in farms. “Our underwater vehicles have a wide range of applications. For example, they are also suitable for detecting and verifying archaeological artifacts at the bottom of lakes,” the researchers explained.
