Problems solved by technology

Among them, inertial guidance uses gyroscopes or encoders for navigation. The path layout is flexible and does not require wires. However, due to the integration of navigation information, the measurement error of the sensor also has an integral effect on the positioning error, so that the positioning error will increase over time. With the passage of time, it continues to increase, resulting in inaccurate positioning of the AGV, which affects the working efficiency of the AGV
