JTT Rescue Case Information Date Oct 21, 2019 Location Gold Coast, Australia Challenges & tasks Emergency Rescuing in the very early morning Solution Integrated air-sea solution Results Quickly & urgently rescued in an unmanned way Device Water Rescue Robot R1 & Drone C85 Case Description On October 21 2019, there was a victim who was rescued by JTT’s Water Rescue Robot R1, an unmanned surface vessel(USV) deployed in the Gold Coast, Australia. It’s often rare to see such case using USV to rescue a person at sea, even on a global scale. Rescue Robot R1 & Drone C85 According to beach management office, the person accidentally fell into the sea at 5 am. Which there are rarely people swimming and playing this early. But the usual work is he basically uses drone C85 to monitor and uses R1 to patrol together. Then he found something weird at sea, as seen a person who was up and down the surface, through drone’s remote control screen and autonomous GPS navigation and intelligent obstacle avoidance function. Plus, R1 follows where drone goes via air-sea linkage. As they were reaching the victim from afar, approximately 200 meters away, the integrated speaker on the USV comforts “Hi sir, please stay calm. We are coming soon.” 28 seconds after it spoke, the rescue robot arrived. Then it speaks with the victim telling him to grasp it. The victim realized there’s something he can grasp of, then he held it finally. Eventually, he was sent back to the shore with rescue robot R1 and with drone C85 above watching him. That was a collaboration system between the drone and water rescue robot that help rescue those who drown, using air-sea linkage where beach guard can check out where the victim is while the robot is following the drone and reaching to save the victim. Business Pain Points 1. Few people at the beach in the early morning which makes it harder to rescue in time 2. One person cannot carry much of the rescue kits to execute rescue 3. It’s basically slow to reach a person while he or she is getting drowned 4. It’s hard to supervise the whole area to see if there’s an abnormal situation Solutions & Advantages 1. Integrated air-sea solution(drone C85 & rescue robot R1) provides farther sight and range to rescue 2. Drone supports GPS where it can locate where the victim is 3. Rescue robot R1 can be equipped with speaker and other payloads to better function in many different rescue application scenes 4. Patrolling at the beach using drone and rescue robot together enhances the work efficiency day and night Results & Values 1. Compared with the traditional method of rescuing, air-sea rescue surely increases the efficiency and safety as a new solution 2. Air-sea solution saves much cost, having its unique searching capability 3. Traditionally, staff charges weekly or monthly but devices are operated without time limit, increasing work efficiency and meaning less cost of supervising the beach and water area 4. It also lowers the ri...

JTT Rescue Case Information Date August 10, 2020 Location Hainan, China Challenges & tasks Saving a kid in swift water Solution Unmanned rapid rescue Results Rescued in 21 seconds from 150 meters Device Water Rescue Robot R1 Case description Marine firefighters and rescuers in Hainan are getting trained through a marine rescue lesson about how to operate a new remote controlled buoy, the Water Rescue Robot R1, during flood control and rescue, which enables them to save lives without setting foot in the water. Rescue Class Given by Emergency Department Using R1 The new device has been deployed following a series of incident along the river, for example, the device was put into action for the first time at the weekend. They firstly used it to patrol on water as it supports APP where they can see the situation through the app, then there’s a kid accidentally fell into the river, but luckily they were right patrolling then they set the route on screen and went to save the kid from which it was swift water down under. The duration of going to reach the kid only takes 21 seconds from 150 meters. Rescue Robot R1 on the Way “It’s just a few minutes away from getting helpless when one gets drowned on water. So Water Rescue Robot R1 is of a smart lifebuoy that provides a few quite pivotal moments before emergency service gets there.” Said Zhen He, a member of marine rescuer in Hainan. Business Pain Points 1.Lack of rapid rescue device along the river 2.There’s usually a strong current down the water where victim might be moving 3.When winter comes, it’s making it harder to save a person immediately 4.There might be lots of kids playing along the river, causing risks of getting drowned Solutions & Advantages 1.Water rescue robot R1 can go at the speeds of 7m/s 2.It can be put along the river where people can get and throw it into the river and get the rescue operation started whenever they need 3.It supports APP where you can set the route on Results & Values 1. It takes shorter time to launch a rescue operation before the rescuers get there 2. It saves cost of staff patrolling along the river and it goes faster when patrolling while using App on their phone

JTT Rescue Case Information Date July 19, 2020 Location Sichuan, China Challenges & tasks Emergency Rescue Against Flooding Solution Air-sea solution Results Rescued in floods Device Water Rescue Robot R1 & Drone C85 Case Description On July 19 2020, that was a day raining heavy and flooding in Mianyang, Sichuan province. Emergency Department deployed rescue teams to relocate villagers and save those who were in danger, using high-tech products to combat the disaster. Drone and water rescue robot, a kind of unmanned surface vessel(USV), joined the battle against flood that caused danger in lives and properties loss, with rescue teams together. According to Emergency Department, there was a person who fell into a street with flood around with 1.4-meter depth but luckily got stuck right there. While drone C85 was patrolling above to observe the whole flooding situation in the village, a rescuer found that there’s a person there struggling and waving at it. Yet, the thing was the distance was quite far away from where the rescue boat was - it was 2 kilometers away - and the flooding had made everything so chaotic on the way which had made the boat difficult to get through the obstacles immediately. So taking the victim to a safer place from the point he could be taken away by flood anytime was literally an emergency by far. Emergency Department Deployed Rescue Robot R1 The rescuer then came out with a method using JTT Integrated Air Sea Solution which is a drone & rescue robot collaboration system for long distance rescue especially for this kind of situation. Rescuer deployed water rescue robot R1, as the drone had been patrolling already. R1 then automatically extended its range to 8km under air-sea linkage. The rescuer subsequently used APP that can plan the route of where rescue robot R1 went, using autonomous GPS navigation and intelligent obstacle avoidance function for R1. Integrated Air-sea Solution As they were reaching the victim, drone was playing 4k video of how it was going while R1 was saving the victim. As it gradually came close to him, he grasped it properly then rescuer used the highest speed of R1 to drive through the current to a safer place where there’s no such danger in the middle of the street. He then finally reached a place full of sacks of sand and climbed it up to the sand. Emergency Department then arrived a few minutes after. That was a collaboration system between the drone and water rescue robot that helped rescue those who were in danger even in disaster, using air-sea linkage where Emergency Department can check out where the victim is while the robot is following the drone and reaching to save the victim. Business Pain Points: 1.Hard to get through the obstacles when using boat 2.It normally takes long for the service team gets there to rescue a person while he or she is getting drowned already 3.Difficult to find victims in floods across the whole area 4.Higher cost of using helicopter to command ...
