The application of environmental perception and micro-robot attitude measurement and control is developed based on a 3-axis MEMS accelerometer with digital output LIS3LV02DL.The design of hardware system is introduced.The principle of environmental perception and micro-robot attitude measurement and control by accelerometer is analyzed.In order to improve the measuring precision of accelerometer

a calibrating method of accelerometers is presented.The results show that the accelerometer can percept the attitude and direction of the robot motion

adjust the robot landing attitude and monitor the vibration information of environment well.
