Inertial measurement units (IMUs) measure a moving object’s orientation, velocity, and acceleration. They are used in various applications, including navigation, robotics, and gaming. But it’s important to have a deeper knowledge of what they can and cannot do, and what are the advantages and disadvantages we can encounter when working with them. Let’s go through what we can expect from an inertial measurement unit.
When considering an investing in one, there are some basic advantages and disadvantages that can be found on an Inertial Measurement Units can include the following:
Inertial Measurements Units have several advantages, including:
- They are small, lightweight, and relatively inexpensive.
- They can be used in various environments, including those without GPS.
- They can provide continuous measurements, even when the object is moving rapidly.
However, Inertial Measurements Units also have some disadvantages, including:
- They can drift over time, making their measurements less accurate.
- They are susceptible to noise, which can also degrade their accuracy.
- They require calibration to ensure that they are providing precise measurements.
Advantages of IMUs
The following are some of the benefits of IMUs:
- Small, lightweight, and relatively inexpensive. IMUs, such as GPS, are typically much smaller and lighter than other navigation systems, which makes them ideal for applications that require size and weight, such as robotics and wearable devices.
- It can be used in a variety of environments. IMUs can be used in various environments, including those without GPS, which makes them ideal for applications such as navigation in tunnels or underground.
- Can provide continuous measurements. IMUs can provide continuous measurements, even when the object moves rapidly, making them ideal for tracking a vehicle’s or a person’s motion.
Disadvantages of IMUs
The following are some of the disadvantages of IMUs:
- It can drift over time. The accuracy of IMU measurements can degrade over time due to drift, which means that the IMU may slowly lose its ability to accurately measure the object’s orientation, velocity, and acceleration.
- They are susceptible to noise. IMU measurements can also be affected by noise. This noise can come from various sources, such as vibrations, electromagnetic interference, and temperature changes.
- Require calibration. IMUs typically require calibration to ensure that they are providing accurate measurements. This calibration process can be time-consuming and complex.
How to Choose an IMU
Here are some tips for choosing an Inertial Measurement Unit, besides the advantages and disadvantages of the unit that you need to consider:
- Consider the application. What will the IMU be used for? The range of measurements, accuracy, noise level, and price will vary depending on the application.
- Consider the environment. Where will the IMU be used? The IMU will need to be able to withstand the environmental conditions of the application.
- Consider the size and weight. The size and weight of the IMU will be vital if it will be used in a mobile application.
- Consider the power requirements. A battery or an external power source must power the IMU.
- Consider the cost. IMUs can range in price from a few hundred to several thousand dollars.
Once you have considered these factors, you can start to narrow down your choices. You can read IMU reviews of IMUs online or consult an Inertial Labs expert to help you choose the right IMU for your application.
IMUs are a valuable tool for a variety of applications. However, they have some disadvantages that can limit their accuracy and performance.
