To transport goods with an AGV from one place to another as quickly as possible, the vehicle must continuously report its location to a central computer. The computer then uses the transmitted position data to calculate the optimal driving route for the vehicles and sends the coordinates to the computer on board the AGV. Precise position data from the AGV is essential for this to work: Rotation rate sensors (gyroscopes) and inertial measurement units (IMUs) from ASC perform a key function in this process. Due to their low bias instability of 9°/hr the ASC 271 and ASC 273 gyroscopes provide very precise rotation rate measurements. The IMU 8 from ASC even features a bias instability of 0.12°/hr.
That is sufficient for a flat AGV with an integrated absolute position system. For larger vehicles without their own position system, the additional use of the IMU 7 or IMU 8 is recommended. In addition to the rotation rate sensors they also feature a series of high-precision acceleration sensors. Designed for outstanding long-term stability and low noise, they reliably measure position changes in all six degrees of freedom with high repeat accuracy.
