What it does
The rescue robot can determine the position of the person in the water and the robot through the sensing device, quickly inflate the airbag to inflate, and rely on buoyancy to lift the person from the water.
Your inspiration
The idea came from real-life drowning accidents where rescue often arrives too late. I was inspired by how fast response and flotation are crucial. By combining sensors and automatic inflation, I wanted to design a robot that could quickly locate and lift a drowning person to safety. This solution aims to reduce rescue time and increase survival chances.
How it works
The rescue robot uses infrared and ultrasonic sensors to detect the position of the drowning person and itself in real time. Once a drowning person is detected, the robot activates a rapid inflation system driven by a high-pressure gas cylinder or air pump. The airbags quickly expand around the victim, providing immediate buoyancy. The robot’s control system ensures stability and precise positioning during inflation. This autonomous process minimizes manual intervention, greatly increasing rescue efficiency and safety.
Design process
The idea began with analyzing real-life rescue delays in drowning accidents. I brainstormed ways to combine sensor technology and automatic inflation. First, I sketched initial concepts and selected suitable components such as infrared sensors, an ultrasonic module, and a compact air pump. I used CAD software to model the robot and 3D printed the shell. The first prototype focused on detecting targets, but accuracy was limited. I adjusted the sensor angle and algorithm to improve detection. The inflation system was then tested with different airbag materials to ensure durability and fast expansion. After several iterations, I optimized the control logic for better timing and safety. User tests showed improved reliability and faster response, proving the design’s effectiveness in emergency scenarios.
How it is different
Unlike traditional life-saving equipment that requires manual operation, this rescue robot features autonomous detection and response. Its unique combination of infrared and ultrasonic sensors ensures accurate positioning of the drowning person. The automatic inflation system rapidly deploys airbags, lifting the victim above water without human assistance. Its compact design and real-time responsiveness make it highly effective in urgent rescue situations, reducing delay and increasing survival rates.
Future plans
In the future, I plan to enhance the robot’s AI for better target recognition in complex environments. I will also improve waterproofing, reduce size, and test in real water scenarios. Eventually, I hope to collaborate with rescue organizations to bring the product into practical use and save more lives.
