Design of a Snake-Liked Robot for Rapid Injury Detection in Patients with Hemorrhagic Shock

In the face of the demand for emergency treatment of sudden and mass hemorrhagic shock in mass casualty incidents, disaster sites are often limited in search and rescue manpower and medical detection capabilities. With the rapid development of robot technology, the deployment of robots provides greater flexibility and reliability for disaster emergency response and search and rescue work, which can effectively address the shortage of search and rescue forces and medical resources at disaster sites.This paper designs a snake-like robot for the rapid triage of casualties with hemorrhagic shock. Through the structural design combining active wheels and orthogonal joints, it can integrate the advantages of high movement speed of wheeled robots and high flexibility of joint robots, so as to adapt to the complex environment of search and rescue scenarios. Meanwhile, the end of the robot is equipped with a visible light camera, an infrared camera and a voice interaction system, which realizes the rapid triage of casualties with hemorrhagic shock by collecting the visible light, infrared and voice dialogue data of the casualties.Through Webots software simulation and outdoor site simulation experiments, seven indicators of the designed snake-like search and rescue robot are verified, including walking speed, minimum passable hole size, climbing angle, obstacle-surmounting height, passable step size, ditch-crossing width and turning radius, as well as the effectiveness of collecting the visible light images, infrared images and voice dialogue data of the casualties.
