The Balance Organ of Humanoid Robots
Xsens inertial sensor modules act as the “inner ear” of humanoid robots: delivering real-time orientation and balance data that keeps robots upright, stable, and safe in dynamic environments.

Helping Humanoid Robots to Walk, Run, and Recover Like Humans
Humanoid robots are leaving the lab and entering the real world. But to walk, run, and recover like humans, they need more than just programmed motion: they need balance.
Xsens industrial-grade inertial sensors give humanoids the ability to maintain stability under real-world conditions: uneven terrain, sudden pushes, vibrations, or magnetic disturbances. With high-frequency data, robust sensor fusion, and compact OEM form factors, Xsens sensors are trusted by leading robotics companies worldwide to keep their humanoids on their feet.
Why Xsens for Humanoid Robots?
Balance Like Humans
Xsens IMUs act as the robot’s inner ear, enabling natural, human-like stability.
High-Dynamic Accuracy
Up to 400 Hz orientation output for fast, precise control loops and agile recovery.
Compact & Efficient
OEM and SMD modules (as small as 12×12 mm), with low power consumption.
Developer-Ready
ROS 1/2 drivers, Nvidia Jetson-ready, cross-platform compatibility and plug-and-play APIs to accelerate integration.

Addressing the Challenges of Balancing a Humanoid Robot
-
Robots tend to lose balance under dynamic conditions.
Xsens sensor solutions provide high-rate inertial feedback (up to 400 Hz) for immediate posture adjustments. -
Commodity IMUs drift too much
All Xsens sensors are industrial-grade and come with advanced sensor fusion, ensuring robust and drift-resistant orientation. -
Integration often takes too long
We provide ready-to-use ROS 1/2 drivers, Nvidia Jetson compatibility, and open-source SDKs to speed up development. -
Space and power are limited
Xsens compact modules with OEM/SMD form factors and low power consumption fit humanoid design constraints.
