From running to jumping, how does IMU help robots perform difficult movements?

IMU is crucial for the robot's balance maintenance and action execution. The world's leading robots have built-in IMUs to achieve precise motion control.

The accuracy and cost of IMUs vary depending on the application scenario. Robots require higher-precision IMUs, which usually means higher costs.

We have a consumer-grade IMU ER-MIMU-M01A. Compared with other IMUs, it has a very advantageous price, the king of cost-effectiveness, no high cost, so that creativity is no longer limited. It can be used for various types of robots.

Small size and easy to install

The size of this IMU is only 23.7×23.7×9.9mm and it weighs only 25g. It can be easily installed anywhere.

Posture control and balance maintenance

ER-MIMU-M01A built-in gyroscope has a measurement range of 450º/s, bias instability of 2 º/h, and angular velocity random walk of 0.15º/√h. The accelerometer has a measurement range of 16g, bias instability of 0.025mg, and bias repeatability of 0.2mg.

IMU measures the robot's angular velocity and acceleration to calculate the robot's posture information, allowing the robot to accurately adjust its posture and maintain stability. It can guide the robot to adjust its gait, turn, or maintain balance, especially in uneven or dynamically changing environments. Its data quality directly affects the robot's motion performance.

High-difficulty action execution

The robot can perform various actions more accurately, such as running, jumping, and going up and down stairs. Complex actions are easily controlled, all thanks to the precise assistance of IMU.

For example, Tesla Optimus Gen2 adds IMU to the sensor, and the high-difficulty actions of the whole body mainly rely on IMU. In addition, IMU data can also be used for path planning to help the robot plan the optimal route of action.
