Autonomous Emergency Rescue Robot in Water based on Cloud Edge Collaboration

Abstract

With the increase of global marine activities, overboard accidents are frequent, especially in the fields of tourism, fishery and shipping. Existing unmanned lifeboats have significant shortcomings in terms of stability and applicability, especially performing poorly in complex marine environments with waves up to 1.5 meters and above. To this end, this project designs a cloud-side collaboration-based autonomous emergency rescue robot for waters, based on the Small Waterline Surface Catamaran (SWATH), combining its advantages of good wave resistance and fast speed, aiming to improve rescue efficiency and stability. The U-shaped floater design enhances wave resistance and stability, which aligns with findings from previous studies on SWATH vessels. In addition, the robot is equipped with a forward drag-reducing obstacle-avoidance structure, which effectively avoids entanglement of water plants and other obstacles through streamlined design. The rear round-up lifesaving mechanism can quickly rescue unconscious or non-swimming drowning people, expanding the rescue range and shortening the rescue time. The design is not only applicable to lakes and rivers, but also can operate efficiently in the sea with frequent waves and under adverse weather conditions, providing more protection for the safety of human life at sea. Combined with the Cloud Edge Collaboration technology, the robot realizes intelligent and automated rescue, significantly improves rescue efficiency and safety, and provides innovative solutions for the development of future water rescue equipment.
