In smart warehousing and flexible manufacturing scenarios, the large-scale deployment of autonomous mobile robots (AMRs) faces three major navigation challenges: heading deviation caused by ground slippage, positioning drift during sharp turns, and multi-robot collaborative conflicts. Traditional laser SLAM or visual navigation fails when features are missing, while high-performance MEMS IMUs build an "inertial nervous system" for AMRs through multi-axis motion perception and fusion algorithms.

High-performance Micro-Electro-Mechanical Systems (MEMS) Inertial Measurement Units (IMUs) enhance Autonomous Mobile Robot (AMR) navigation by providing continuous, high-rate motion data that is fused with other sensor information to mitigate the shortcomings of traditional navigation methods. This integrated approach addresses major challenges in smart warehousing: 

1.     Overcoming the slippage problem and ensuring heading stability: On polished surfaces and during sharp turns, wheel encoders completely fail. A high-performance IMU provides an absolute heading reference, detects and compensates for heading errors caused by slippage in real time, ensuring the AMR travels precisely along the predetermined trajectory and fundamentally eliminating "drifting."

2.     Achieving millimeter-level precise docking: When docking with racks and charging stations, centimeter-level errors mean mission failure. High-frequency attitude data and motion prediction provided by a high-performance IMU enable the AMR to achieve millimeter-level terminal positioning, ensuring accurate docking every time and greatly improving operational reliability.

3.     Enabling intelligent collaboration: In multi-machine collaborative operation scenarios, high-performance IMUs provide a unified high-precision spatiotemporal reference for each AMR. Through IMU/UWB tight combination technology, positioning conflicts between individuals are eliminated, achieving true millimeter-level obstacle avoidance and dynamic path optimization, making cluster scheduling as easy as controlling your own arm.

4.     Improving dynamic control quality: The start-stop and turning experience of an AMR directly affects its operational efficiency and safety. The high-frequency motion sensing of the IMU provides forward-looking information to the control system, enabling smoother speed planning and vibration suppression, making the robot run more stably and quietly.
