FAQ

1. Why is calibration of a six-axis force sensor important?

A six-axis force/torque sensor measures forces and torques simultaneously in multiple directions. Calibration ensures the sensor outputs accurately correspond to applied loads, improving the reliability of robot force control, collision detection, assembly operations, and precision manipulation.

2. What is the purpose of multi-axis combined loading?

In real applications, forces and torques rarely occur independently. For example, a humanoid robot hand may experience gripping force, lateral force, and rotational torque simultaneously.

Multi-axis loading verifies how accurately the sensor performs under these coupled load conditions and evaluates cross-axis interference characteristics.

3. What parameters can be calibrated on this system?

The system can calibrate all six channels of a force-torque sensor:

• Fx (X-direction force)

• Fy (Y-direction force)

• Fz (Z-direction force)

• Mx (Roll torque)

• My (Pitch torque)

• Mz (Yaw torque)

It can also generate calibration matrices and evaluate sensor linearity, repeatability, and coupling errors.

4. How does the automatic calibration process work?

The software automatically performs:

1. Incremental force/torque application

2. Load stabilization and holding

3. Sensor data acquisition

4. Multi-point calibration analysis

5. Automatic unloading

6. Calibration report generation

This eliminates operator variability and improves testing consistency.

5. Which industries commonly use six-axis force sensor calibration systems?

The system is widely used in:

• Humanoid robot development

• Collaborative robots (Cobots)

• Industrial robot end-effectors

• Aerospace force measurement systems

• Medical robotic devices

• Research laboratories

• Force/torque sensor manufacturing

• Automotive testing and automation industries

These applications require highly accurate force measurement to ensure safety, precision, and control performance.
