IMUta

IMUta is a modular inertial measurement unit designed for real-time attitude and motion tracking. It integrates a 3-axis gyroscope, a 3-axis accelerometer, and a 3-axis magnetometer, with optional barometric pressure sensor and a GNSS receiver. Onboard processing, via a microcontroller or system-on-chip, performs sensor fusion to deliver orientation in quaternion or Euler form, together with angular velocity and linear acceleration. Some configurations include a digital motion processor to reduce latency for control applications.

IMUta variants come in compact form factors suitable for drones, wearable devices, and robotics. Interfaces typically include I2C or SPI for sensors, with additional UART, USB, CAN, or wireless links for host communication. Output data rates are high enough for real-time control and post-processing, and many deployments support configurable fusion algorithms, such as complementary filters or extended Kalman filters, to balance responsiveness and accuracy. Calibration usually combines factory offset estimation with on-device auto-calibration routines to mitigate bias drift and magnetic distortion.

IMUta is used in a range of fields, including robotics, unmanned vehicles, augmented reality and virtual reality, motion capture, and biomechanics. The term IMUta is a blended form of IMU and attitude, and is sometimes presented as an open hardware/software reference design in academic and maker communities.
