What are the features of a 3D force sensor?

Release Time:

2025-11-01

A 3D force sensor can be used to measure forces acting in three directions. Made from high-quality alloy steel, these sensors feature a robust design with multiple weather-resistant sealing solutions, offering exceptional corrosion protection. Operating on the principle of resistance strain gauges, they enable real-time measurement of both static and dynamic forces applied to an object along the X, Y, and Z axes. This series of sensors is available in three optional load capacities per channel.

As a multi-directional force measurement device, the 3D force sensor simultaneously detects three force components in the robot’s 3D space (Fx, Fy, and Fz). Through its integration into the control system, this sensor not only enables precise detection and control of the gripping force when the robot hand picks up objects but also allows monitoring of the object’s weight—as well as identifying whether the object is slipping or vibrating during the grasping process. The 3D force sensor comes in two mounting types: side-mounted and top-mounted. The side-mounted 3D force sensor is typically used in two-fingered robotic grippers, while the top-mounted version is commonly employed in multi-fingered, dexterous robotic hands.

How does the multi-dimensional force sensor enhance calibration efficiency?

Typically, a Design Of Experiment (DOE) is employed to generate a scientifically sound load table, while Regression Analysis (RA) is used to establish the functional relationships between dependent and independent variables. Ultimately, the calibration matrix obtained depends heavily on both the load table and the regression analysis method applied. Established force measurement laboratories usually have their own standardized procedures for acquiring and processing this data—though sometimes the individuals directly involved in calibration work may not even be fully aware of the underlying data calculation processes driving the calibration workflow.

Three-Dimensional Force Sensor Calibration Data Processing Method

To simultaneously measure multi-component forces and torques, a multidimensional force sensor is required, which inevitably demands calibration before use—otherwise, the conversion from electrical signals to physical force values cannot be accurately achieved.

Calibration Method for Six-Dimensional Force Sensors

Calibration of multi-component force sensors aims to establish the relationship between the signal and the applied force. The calibration process can be expressed as a quadratic polynomial. Interestingly, this representation differs slightly from what’s typically found in domestic textbooks—where we usually place the force F on the left side of the equation. From the perspective of the calibration procedure, however, this arrangement seems more logical, since it reflects applying a specific force and subsequently measuring the corresponding signal.
