The Key to Motion Sensing and Effective Control in Unmanned Systems – IMU Stable flight of drones, precise robot control, and industrial automation all rely on high-precision, high-reliability motion sensing. Insufficient sensing data quality or latency will prevent efficient closed-loop control. Although these devices commonly use IMUs for motion sensing, the conflict between high-performance requirements and strict cost budgets persists.
The ER-MIMU-M01A MEMS IMU breaks through the industry bottleneck of "high performance = high cost" with its superior performance and controllable cost, becoming the core "motion nerve center" in complex dynamic environments.
Miniaturized Packaging and High Integration Utilizing advanced MEMS technology, a three-axis gyroscope and a three-axis accelerometer are integrated into a miniature space of only 23.7mm x 23.7mm x 9.9mm and weighing 25g. This facilitates embedding in compact structures such as drone flight controllers and robot joints, optimizing system layout.
High-Performance Inertial Sensing Gyroscope: Measurement range ±450°/s, covering high-speed rotation and sharp turning scenarios. Full-temperature bias ≤36°/h, bias instability ≤2°/h, and angular random walk ≤0.15°/√h, ensuring the stability of attitude calculation during long-term operation and effectively suppressing cumulative drift.
Accelerometer: ±16g measurement range adapts to severe motion, full-temperature bias ≤3mg, bias instability ≤0.025mg, stability (1σ) ≤0.2mg, accurately capturing minute linear accelerations, supporting fine movements and disturbance rejection control.
Attitude Stability and Agile Control: The high-frequency angular velocity and acceleration data provided by the IMU are the foundation for the flight control system to achieve accurate attitude estimation and high dynamic response, helping the UAV to hover stably in strong winds and supporting complex flight maneuvers. On the robot platform, the IMU senses steering angular velocity and displacement in real time, ensuring path tracking accuracy; when installed at joints, it can monitor rotation and acceleration, working with servo motors to achieve smooth movement and safe interaction. In the robotic arm, the IMU enables trajectory tracking, collision detection, and force-position hybrid control, improving operational smoothness and intelligence.
With its advanced MEMS technology, the ER-MIMU-M01A precisely meets the stringent requirements of drones, robots, and automated equipment for high-performance and highly reliable motion sensing, becoming a core component supporting intelligent control and autonomous operation.
