An automatic table leveling system includes a linear accelerometer, a microcontroller, motor drivers, motors and lead screws. The microcontroller reads linear accelerometer sensor information which indicates the table top's attitude with respect to the gravity vector. Then the microcontroller sends signals to the motor drivers to cause the motors to drive the table legs up or down via a lead screw mechanism. The changed leg lengths adjust the attitude of the table top to make it level.
