Abstract:With the frequent occurrence of natural disasters, the number of casualties of rescuers is increasing, and the robots to complete rescue work instead of human beings has become a research hotspot. Based on the analysis of the research findings in relevant international fields, a bionic four-legged robotic dog with high stability and strong environmental adaptability was designed. The whole body frame is made of carbon fiber, equipped with a large torque motor and combined with the tank chassis and the six-degree-of-freedom mechanical arm to achieve the forward mode conversion in different terrain environments. Based on the elbow-knee legs of the robot and combined with ADAMS simulation, stable walking is achieved. Combined with gas detection and image recognition modules, it can complete environmental exploration and search-and-rescue missions at the site of the disaster. Based on the principle of stability margin optimization, the gait control method of diagonal gait is adopted. The mechanical design of the 8-degree-of-freedom and the elbow-knee bionic four-legged robotic dog and its gait control scheme were announced.
