Description
technical field [0001] The invention relates to a calibration device, in particular to a force sensor calibration device and method. Background technique [0002] Equipment calibration refers to the act of testing and adjusting measuring equipment or standard parts to understand their accuracy. [0003] A force sensor is a device that can sense a force signal and convert the force signal into an electrical signal or other signal output. It is widely used in power equipment, construction machinery, industrial automation systems, and human-computer interaction systems. For example, in the field of robotics, many devices are equipped with force sensors for mechanical feedback for human-computer interaction control. [0004] In practical applications, due to various reasons, such as the deviation of the force sensor itself, different equipment for installing the force sensor, and different operating environments, it is easy to cause errors between the indicated value (that is, ...
