Technical Field

[0002] As we all know, forests, as the most widely distributed, most complex and most biodiverse ecosystems on land, play a vital role in our human life. However, the frequent occurrence of forest fires has brought immeasurable losses to the economy and ecological environment. The personal safety of firefighters is seriously threatened during fire fighting, and the complex forest terrain environment has greatly hindered the entry of rescue equipment. In recent years, with the development of science and technology, various types of robots have appeared in all walks of life. In the field of firefighting, the early research and development of firefighting robots focused on firefighting, and there were still deficiencies and gaps in the design and development of avoiding and clearing obstacles. Because the terrain environment of the forest is complex and the situation at the rescue site is changeable, the performance of the firefighting robot is put forward relatively high requirements. At the same time, in terms of firefighting water, because the firefighting facilities in the forest area and the surrounding areas of the forest are not necessarily perfect, and the geographical location is relatively remote, the firefighting vehicles may not be able to reach the firefighting site in time. In order to better improve the firefighting, the firefighting water supply of the firefighting robot cannot rely solely on fire hydrants and fire trucks; therefore, it is particularly important to design a relatively small robot that can replace firefighters in the jungle to carry out firefighting operations in the forest.
