6DOF Triaxial Vibration and Tilt: 6 Signals, 1 Sensor

‍

In today’s rapidly evolving technological landscape, precise motion sensing is crucial for various applications, from industrial machinery and consumer electronics, to drones, aerospace, and defence . The concept of Six Degrees of Freedom (6DOF) sensors is a cornerstone in this field, providing comprehensive motion tracking by measuring translational and rotational movements across three perpendicular axes.

‍

The term “Six Degrees of Freedom” refers to the ability of a rigid body to move freely in three-dimensional space, encompassing three translational movements along the X, Y, and Z axis and three rotational movements—tilting side to side (roll), tilting forward and backward (pitch), and turning left and right (yaw). This extensive range of motion is vital for applications requiring precise positioning and orientation data, such as robotics, aerospace, and virtual reality systems.

Applications and Use Cases

The Series 7576AX is ideal for applications requiring precise monitoring of translational and rotational motion components at the same physical point. This capability is particularly useful in determining the center of rotation of a rigid body in space, a critical factor in many industrial and commercial applications.

Measuring Tilt and Angular Velocity

Tilt and angular velocity measurement are key functionalities of the 7576AX sensor. Static tilt can be monitored by the X and Y acceleration output axes, where deviations from the 2.5 volts bias indicate tilt. As the sensor tilts, the voltage output varies around this bias, and these readings, when combined with gyro outputs from appropriate channels, provide comprehensive tilt and angular velocity data. By applying a Kalman filter to these data points, the angular location of the sensor in space can be precisely determined.
