Summary: Unmanned technologies such as unmanned aircraft, unmanned driving, unmanned shops, unmanned hotels and unmanned banks have provided a new source of strength for coastal defense islands and border defense to defend the motherland. They have many points of convergence with the needs of coastal defense islands and border defense, and can play a great role in monitoring, dangerous task execution and logistics support. Although it is faced with challenges such as adaptability to complex environment and security and confidentiality in the application process, unmanned technology will be able to better serve coastal defense islands and frontier defense by developing protection technologies and strengthening confidentiality management, and make important contributions to defending the territorial integrity and frontier security of the motherland.1.
