MEMS sensor BMI088 improves the flying and navigation experience
Bosch Sensortec launches the MEMS sensor BMI088, a high-performance Inertial Measurement Unit (IMU) with outstanding vibration robustness, specifically designed for drone and robotics applications.
BMI088 features an extremely stable gyroscope derived from Bosch’s proven automotive technology. The IMU delivers low noise and low drift despite fluctuating temperatures.
The performance, vibration robustness and temperature stability of the BMI088 greatly enhance the drone flying experience by making accurate steering easier even in naturally high-vibration environments. This new IMU is compatible for use with other Bosch sensors, including the BMP38x barometric pressure sensor series for altitude measurement and the BMM150 geomagnetic sensor for heading. Customers benefit from a comprehensive sensor offering that is a perfect match to drone applications – a complete solution from Bosch.
The BMI088 is also a great choice for robotics applications, including industrial robots, domestic appliances such as vacuum cleaners and social robots, as well as e.g. hoverboards. To achieve consistent and reliable navigation accuracy, BMI088 suppresses the vibrations coming for example from rough terrain and built-in motors.
The BMI088 consists of a triaxial 16-bit acceleration sensor and a triaxial 16-bit gyroscope. With this IMU, Bosch has combined automotive-proven gyroscope technology with a new low-TCO accelerometer design. The BMI088 is pin-to-pin compatible with the BMI055, thus simplifying integration into existing designs, and is housed in a compact 3.0 × 4.5 × 0.95 mm3 package.
The automotive-proven gyroscope of the BMI088 has an unmatched bias stability of less than 2°/h and a low temperature coefficient of offset (TCO) below 15 mdps/K. The accelerometer also features a low TCO of 0.2 mg/K and low spectral noise of only 230 μg/√Hz in the widest measurement range of ±24 g.
The BMI088 will be available for OEMs and distributors starting in May 2018.
