[Purposes]The existing video intelligent car is designed to solve the problems of limited motion scenes,jittery video images and complex reversing modes.[Methods]On the one hand,the suspension device can automatically match the relative angle with the ground through a rotatable connection,and on the other hand,the shock absorber of the suspension device can align the vehicle body through physical balance.The reversing device adopts parallelogram reversing device.In the balancing device,the signal is transmitted to the main control chip through the gyroscope and acceleration sensor,and the main control chip controls the built-in driving motor of the stability device to correct the angle through the built-in algorithm.[Findings]The stable movement of complex terrain was realized,and the mobility of the intelligent car and the stability of video transmission pictures were improved.By taking advantage of the characteristics of parallelogram,it can be more quickly and smoothly reversed.[Conclusions]Finally,the problems such as the limited motion scene of the intelligent car,the jitter of the video picture and the complex reversing mode are solved.
