The most impressive application of AGV(Automated Guided Vehicle) is the express delivery industry. In a large warehouse, dozens of AGV operate alternately. They are so fast that the manual only need to stand at the end of the goods stack to put the goods in the starting position. AGV trolleys do not interfere with each other, accurately classify cargo handling, during which they have the opportunity to touch each other, but do not hinder each other's direction, as AGV has the function of avoiding obstacles. So, how to achieve this function?
How AGV realize automatic avoiding obstacles?  Firstly, a sonar positioning system is installed on the body of AGV, which can send sound signals to the surrounding environment, so as to analyze the surrounding obstacles in time. Sound signal transmission needs a sound wave generator, which is in a continuous working state. It does not know when there will be obstacles, so the signal transmission and reception is very important. The signal obtained through sonar system analysis will give a feedback to the equipment and inform it to respond accordingly. Whether it stops or evades depends on the results of data analysis. This requires a computational system, which can quantify the signal and operate according to the strength of the signal, rather than simply looking at the presence or absence of the signal.

  Secondly, sensitive reaction mechanism. Signal can receive analysis, and the result of analysis is strength action, so sensitive reaction mechanism can definitely transform signal into action. AGV is small enough, it is not difficult to move, but it needs to be sensitive when carrying cargo, which requires adding shock mitigation design in the machine connection, so that no matter the direction of change or slow stop will produce dumping of cargo.
