Description

technical field [0001] The invention relates to the technical field of silicon microgyro, in particular to a silicon microgyro interface circuit suitable for attitude measurement of industrial robots. Background technique [0002] During the working process, industrial robots must continuously detect the motion posture of the robot to achieve precise control of the robot, so as to ensure the normal operation of the industrial robot. Therefore, the attitude measurement technology of industrial robots has become a research hotspot. The traditional attitude measurement method requires external information sources as a guide , there are certain requirements for the working environment of the robot, which makes the positioning of industrial robots have certain limitations and is easily disturbed by external factors. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, the object of the present invention is to provide a silic...
