3. Unmanned shops, hotels and banks: a new form of service upgrading.Unmanned Technology: Injecting New Vitality into the Sustainable Development of Northeast Economic CycleThe climate in Northeast China is cold, and the terrain in some areas is complex. For example, the battery life of drones decreases in a low temperature environment, and the sensors of unmanned vehicles may fail in ice and snow weather. In view of these problems, scientific and technological enterprises need to intensify research and development to develop unmanned scientific and technological products that adapt to the special environment in Northeast China. The applicability of unmanned technology products in Northeast China can be improved through the research and development of cold-resistant battery technology and the design of ice and snow protection for sensors.
