Choose a suitable IMU to make your drone flight more stable and safe

 

       As one of the core components of drones, IMU plays an irreplaceable role. Its high precision, fast response and freedom from external interference enable drones to maintain stable and precise flight and accurate navigation and positioning in complex environments, and can also perform fault diagnosis for drones. ERICCO's MEMS IMU can achieve high performance while being small in size and light in weight, making it very suitable for drones.

We have a tactical-grade IMU ER-MIMU-M02, which is low-cost and has an advantage in price. It is a 10-axis IMU with an added three-axis magnetometer and barometer (altimeter). It is only 47×44×14mm in size and weighs 50g. Compared with other IMUs, it is more suitable for drones.

The built-in accelerometer of the IMU cannot be used to detect absolute heading (yaw). The magnetometer in this IMU measures the magnetic field strength in three dimensions, which can help determine the heading of the object as well as roll and pitch, and correct the integrated error of the yaw gyroscope in the sensor fusion algorithm.

The barometer measures the atmospheric pressure and calculates the altitude of the drone, which is crucial for the safe flight of the drone!

The dynamic measurement range of the built-in gyroscope is ±450º/s, the bias instability is 2 º/h, and the angular random walk is 0.08º/√h. The dynamic measurement range of the accelerometer is 16g, the bias stability is 0.1mg (Allen variance), and the angular random walk is 0.02m/s√h.

Considering the flight time requirements of drones, this IMU has a power of only 1.5W, which can extend the flight time of drones.

This IMU has a short production cycle and can be mass-produced, which is particularly suitable for users with large demands and limited budgets.

Do you know what can make drone flights more stable, safer and more widely used?

The key to achieving autonomous navigation, stable control and precise flight of drones is closely related to IMU, which is one of the core technologies of drone systems. At present, there are also research teams that have developed IMU-centric data-driven diagnostic methods to perform fault diagnosis on drones without the need for additional sensors. Choosing the right IMU can make flight more stable and safer.

ERICCO's MEMS IMU ER-MIMU-07 and ER-MIMU-03 (OEM customization is available) can be used in drones. Using MEMS technology, they are small in size, superior in performance, light in weight, low in power consumption, and cost-effective, and are very popular among users.

Drones have strict requirements on the size and weight of IMUs. The ER-MIMU-03 has a size of (43.2×43.2×35.5mm (without shell), 65×70×45.5mm (with shell)) and a weight of (≤100g (without shell), ≤220g (with shell)).

The ER-MIMU-07 is a very small IMU, measuring only 38.6 x 44.8 x25.5mm and weighing less than 70g, which is suitable for drones with higher IMU requirements.

Flight control of drones is one of their most basic functions. MEMS IMU helps drones maintain a stable attitude by providing real-time acceleration and angular velocity data.

The gyroscope measurement range of ER-MIMU-03 and ER-MIMU-07 is ±400deg/s, bias instability <0.3deg/hr, angular velocity random walk <0.15°/√h, accelerometer bias repeatability 5mg, and second-order nonlinear coefficient <100μg/g2. At the same time, it has the characteristics of low power consumption, which prolongs the flight time of drones.

It can also combine data from other sensors (such as GPS, magnetometer, etc.) to calculate the precise location and attitude information of the drone for navigation and positioning. When the drone is taking aerial photos, it can maintain extremely high stability to ensure the clarity and stability of the images and videos taken. At the same time, it can also be used as part of the drone's fault safety system to detect abnormal movements or attitude changes and trigger automatic recovery procedures or emergency landing procedures to protect the safety of the drone and the surrounding environment.

In the design and application of drones, high-performance IMUs are able to provide stable and accurate data under various environmental conditions, such as temperature changes, vibrations, and rapid movements, and perform precise tasks such as aerial photography, logistics transportation, and agricultural monitoring.

MEMS IMU has many applications in the field of drones. They not only improve the performance and stability of drones, but also expand the scope of application of drones.

What is an IMU and what can it do for your drone?

 

IMU is one of the core technologies of drone(UAV) systems. This information is the key to autonomous navigation, stable control and precise flight of UAVs. Some research teams have developed data-driven diagnostic methods centered on IMUs, using IMUs to diagnose faults for UAVs. IMUs usually contain embedded algorithms, such as sensor calibration and data fusion, which help simplify software development and system integration for UAVs.

ERICCO's MEMS IMU ER-MIMU-07 and ER-MIMU-03 (OEM customization is available) can be used in drones. They are small in size, superior in performance, light in weight, low in power consumption, and cost-effective, making them popular among users. With the advancement of technology, the performance of MEMS IMU continues to improve, while the size and power consumption continue to decrease, and they can be integrated into smaller drone platforms. Please see the picture for detailed parameters of MEMS IMU.

The core functions of MEMS IMU include measuring the linear acceleration, angular velocity, and direction of the drone. The accelerometer is responsible for sensing the acceleration and deceleration of the drone during flight, while the gyroscope measures the rotation of the drone. The data from these sensors is processed by advanced algorithms to provide real-time attitude adjustment and navigation information for the drone.

In the design and application of drones, high-performance IMUs can provide stable and accurate data under various environmental conditions, such as temperature changes, vibrations, and rapid movements. This enables drones to remain stable in complex flight environments and perform precise tasks such as aerial photography, logistics transportation, and agricultural monitoring.

Efficient mining: MEMS IMU unlocks new possibilities for oil and mining

     

    Oil and coal are important basic energy sources. With the rapid development of science and technology, MEMS IMU is increasingly widely used in the fields of oil and mining, injecting new vitality into this traditional industry. Oil and mining are complex and arduous tasks, facing many challenges. Most of these resources are distributed in areas with complex geological conditions. As resources are gradually depleted, the difficulty of exploration and mining continues to increase, which puts higher requirements on exploration and mining equipment.

In response to these problems, ERICCO has developed a new MEMS IMU ER-MIMU-09 specifically for the oil and mining field, which is mainly used in gyroscope tools and directional drilling tools. There are four versions in this series (ER-MIMU-09A, ER-MIMU-09B, ER-MIMU-09C, ER-MIMU-09H), with different accuracy and working temperature, which can be selected according to needs.

New appearance, small size

This IMU is designed for drilling rigs. It adopts a cylindrical shape with a diameter of only 30mm. It can be easily used in the probe tube, meeting the needs of users with higher requirements for tool tube diameters and providing convenience for limited working spaces.

High precision, high performance

Equipped with high-performance three-axis MEMS gyroscope and three-axis accelerometer, the small size does not compromise performance. The built-in gyroscope bias instability is 0.01-0.02deg/hr, and the angular velocity random walk is 0.0025-0.025°/√h. The accelerometer bias stability is ≤0.05mg, and the bias repeatability is ≤0.1mg. It can accurately output angular rate and acceleration information to help drilling engineers accurately control the trajectory of the drill bit and improve operating efficiency.

Strong environmental adaptability

This IMU adopts MEMS technology. In addition to low power consumption, it has good shock and vibration resistance and is not affected by magnetic fields. Considering the special operating environment in the field of oil mining, general IMUs cannot accurately output information in high temperature environments. We divide this IMU into normal temperature version (ER-MIMU-09A, ER-MIMU-09B, ER-MIMU-09C) and high temperature version (ER-MIMU-09H). The normal temperature version has an operating temperature of -40℃~ +80℃, and the high temperature version has an operating temperature of -40℃~ +125℃. It can work continuously in high temperature and harsh environments.
