With the rapid development of intelligent technology, our life is closely related to the intelligent products. A large number of intelligent products have been applied to people's daily life. However, in some extreme conditions such as fire, epidemic situation and other artificial inaccessible environment, intelligent detection vehicle, which integrates a lot of science and technology, plays an irreplaceable role. Based on the background that some special environment of people's daily life needs live image information, this paper designs a smart car which can be remotely controlled and real-time image monitoring can be obtained through WiFi communi- cation mode with smart phone.
