This design work studies the individual exoskeleton suit used in disaster relief, which includes the exoskeleton support structure of the trunk and legs, and the improvement of the combat helmet. It aims to improve the rescue efficiency and ensure their own safety when disasters occur, and can explore the way and transport materials for the last kilometer of rescue in unknown areas. The design idea of this topic is to use the exoskeleton system to assist rescue personnel to carry out rescue and materials and other operations, so as to improve the rescue efficiency of rescue personnel in the "last 100 meters" or complex disaster situations, while better ensuring the safety of rescue personnel and avoiding repeated rescue due to the distress of rescue personnel.
