As the "nerve endings" to perceive the physical world, the force sensor is reconstructing the underlying logic of vehicle performance and safety with micron-scale accuracy. From the engine room to the intelligent cockpit, from the production workshop to the monitoring of driving conditions, the force sensor becomes the core support of the whole life cycle of automobile manufacturing, testing and operation by converting mechanical stress into quantifiable electrical signals. This paper systematically sorts out the types of force sensors commonly used in the automobile industry:

6-axis force sensor is a kind of equipment used to ensure the application accuracy of robot. The sensor is specially designed for robot joints, and is usually installed on the wrist of a manipulator, providing accurate force measurement for all three geometric coordinates (Fx, Fy, Fz) and their surrounding moments or torques (Mx, My, Mz). Force/torque sensors are used in product testing, robot assembly, grinding, polishing and other industrial applications. In these applications, it is necessary to maintain stable position and high repeatability of trajectory.
