Robotic Acoustic Measurement with Universal Robots

Experience the next generation of acoustic testing with Microflown’s robotic measurement solution. By integrating Universal Robots with our acoustic measurement platforms, precise sound field visualization becomes possible in environments where manual operation is difficult, restricted, or unsafe. Mounting Microflown probes on a UR robotic arm enables highly repeatable measurements of stationary and non-stationary sound fields, while extending access to areas that are hard to reach manually.

From Setup to Measurement

A typical measurement process consists of the following steps:

  1. Import Geometry: Import a 3D model into VELO from CAD data or scanned geometry. This model serves as the reference for data visualization and analysis.
  2. Coordinate Alignment: Synchronize the robot and VELO coordinate systems by selecting a set of reference points in VELO and guiding the robot sequentially to these same physical positions. The system automatically calculates the transformation, enabling accurate spatial mapping.
  3. Define Robot Trajectory: Define the scanning path on the robot using standard tools such as the UR Teach Pendant (URCap) or offline environments like RoboDK. The Universal Robot must be connected to VELO via Ethernet, enabling communication through standard TCP/IP interfaces.
  4. Start Measurement: Initiating the scan from the robot interface automatically triggers synchronized data acquisition in VELO, allowing remote and hands-free operation. Acoustic quantities such as sound intensity vectors are visualized live and mapped onto the 3D model as the robot moves.

Enabling Acoustic Measurements in Restricted or Hazardous Areas

Some environments make manual measurements unsafe or impractical, due to moving machinery, extreme temperatures, or strict safety regulations. Robotic integration enables high-quality acoustic measurements without exposing personnel to risk. Whether inside a high-voltage test cell, near operating equipment, or within a test bench with moving parts, robotic scanning allows measurements where manual access is limited.

Robotic Integration Adds Built-in Position Tracking

Traditional scanning systems often rely on external optical tracking. With a robotic scanner, the robot’s internal kinematics provide precise position data in real time, eliminating the need for additional tracking hardware. This simplifies setup, reduces potential error sources, and ensures consistent results, especially in repetitive tests or limited-access environments.

Seamless Integration with Scan&Paint 3D and Acoustic Shape

The robotic system is compatible with both Scan&Paint 3D and Acoustic Shape. In Scan&Paint 3D, the robot performs precise volumetric scans, replacing manual probe movement while maintaining the spatial resolution required for 3D sound intensity mapping. In Acoustic Shape, the robot positions the probe array at predefined locations with high repeatability, eliminating the need for operator presence inside the test environment. Both applications benefit from automated operation and remote handling.

Probe Mounting and Positioning Tools

A dedicated set of accessories ensures reliable robotic measurements. A custom probe adapter keeps the sensor’s position and orientation fixed, with a quick click-in connection. Spacer tools define key scanning locations, allowing controlled surface contact and consistent probe distance, particularly on complex or curved surfaces.
