Inertial Measurement Unit (IMU)

Which IMU is right for you ?

In robotics, the sensor is a key element which plays an essential role that cannot be ignored. These are very important due to their feature like they provide an interface to connect with surroundings. This is the reason they are available in different ranges for different applications. There are some commonly used sensors which include a current sensor, voltage sensor, speedometer, light sensor, and finally IMU sensor. This article discusses an overview of IMU sensor which is known as an inertial measurement unit.

Orientus is a ruggedized miniature orientation sensor and AHRS that provides accurate orientation under the most demanding conditions. It combines temperature calibrated accelerometers, gyroscopes and magnetometers in a sophisticated fusion algorithm to deliver accurate and reliable orientation.

The VN-300 is a miniature, high-performance Dual Antenna GNSS-Aided Inertial Navigation System that combines MEMS inertial sensors, two high-sensitivity GNSS receivers, and advanced Kalman filtering algorithms to provide optimal estimates of position and velocity.

LandMark™007 IMU is a high dynamic six-axis MEMS IMU featuring VELOX™ Processing for low latency high speed outputs. Its low-noise gyros and accelerometers in a compact package make it ideal for use in high dynamic environments with SWaP-C restrictions.

Smallest & Economical IMU, AHRS, INS
Ellipse 2 Micro IMU is an ultra small-sized
Inertial Measurement Unit (IMU). It embeds 3 gyroscopes, 3 accelerometers, 3 magnetometers, and a temperature sensor. This IMU is extensively calibrated from -40 to 85°C.

What is an IMU Sensor?

The IMU sensor is an electronic device used to calculate and reports an exact force of body, angular rate as well as the direction of the body, which can be achieved by using a blend of 3 sensors like Gyroscope, Magnetometer, and Accelerometer. These sensors are normally used to plan aircraft including UAVs (unmanned aerial vehicles), between several others, & spacecraft, comprising landers and satellites. Modern developments permit the manufacture of IMU-based GPS devices.

These sensors let a GPS receiver to function when the signals of GPS are not available like in within buildings, tunnels, otherwise when electronic interference can be there. A WIMU is nothing but a wireless IMU sensor.
