会社ブログについて Supply + Recycling LSM6DSOX: An AI-integrated 6DoF Inertial Sensor, Taking Drone Flight Control to New Heights

Now that drone system design is evolving from ‘perception’ to ‘cognition’, the role of IMU sensors has quietly shifted. They are no longer merely ‘sensory organs’ that provide acceleration and angular velocity data, but have become the central hub for edge intelligence, real-time attitude estimation and vibration-resistant reliability. STMicroelectronics’ LSM6DSOX iNEMO 6DoF inertial sensor is precisely such a key component, tailor-made for the next generation of intelligent drones.

Shenzhen Mingjiada Electronics Co., Ltd. maintains a long-term stock of genuine LSM6DSOX sensors and provides sample support and rapid delivery services to customers in the drone, robotics and industrial automation sectors.

Product Overview: More than just 6 axes – a true edge AI engine

The LSM6DSOX is a System-in-Package (SiP) 6-axis Inertial Measurement Unit (IMU) that integrates a 3-axis digital accelerometer and a 3-axis digital gyroscope. Its core breakthrough lies in the built-in Machine Learning Core (MLC) and programmable Finite State Machine (FSM) — this enables the sensor to independently perform gesture recognition, activity classification and anomaly detection locally, without needing to wake the main control chip, thereby significantly reducing system power consumption. For drones requiring extended flight times, this ‘always-on’ and low-power characteristic is key to optimising flight endurance.

Wide Operating Temperature Range: -40°C to +85°C, suitable for harsh outdoor flight environments

LSM6DSOX Key Features for Drones

1. Machine Learning Core (MLC) and Finite State Machine (FSM)

During flight, drones need to distinguish between ‘hover’, ‘manoeuvre’, ‘drop’ or ‘collision’ states. The LSM6DSOX’s built-in MLC can train decision tree models to perform these classifications locally, thereby reducing the computational load on the flight control MCU. The FSM can detect events in real time, such as free fall, 6D/4D directional changes, and single/double clicks (used to trigger photo capture).

2. Dedicated OIS/EIS Optical Image Stabilisation Path

For drones equipped with gimbal-mounted cameras, the LSM6DSOX provides a dedicated auxiliary SPI interface and an OIS signal processing path. It can directly output high-frequency gyroscope and accelerometer data to the gimbal motor driver, enabling optical image stabilisation (OIS) and electronic image stabilisation (EIS), thereby significantly reducing image shake.

3. Sensor Data Synchronisation (S4S)

Supports data synchronisation with the main processor, ensuring that IMU data is strictly aligned with timestamps from multiple sensors such as GPS, magnetometers and barometers—which is crucial for drone attitude estimation (AHRS) and visual-inertial odometry (VIO).

LSM6DSOX Typical Application Scenarios: Drones

Attitude Stabilisation (AHRS): Low-noise gyroscopes provide precise angular velocity, ensuring convergence of the flight controller’s PID loop

Autonomous Navigation and Obstacle Avoidance: In conjunction with external sensors, 6DoF data supports inertial navigation and path planning

Gimbal stabilisation: By directly connecting to the gimbal’s MCU via SPI, high-speed, low-latency anti-shake control is achieved

Black box logging and fault diagnosis: A 9KB FIFO records transient data prior to a crash, aiding post-incident analysis

Low-power flight mode recognition: The MLC continuously monitors changes in the airframe’s attitude whilst in sleep mode, optimising flight endurance
