ROBOT-VACUUM CLEANER AND CONTROL MODE OF ROBOT-VACUUM CLEANER Russian patent published in 2009 - IPC A47L9/28 

FIELD: items of personal use and for household; mechanic.

SUBSTANCE: robot-vacuum cleaner is meant for dust arrest and similar substances at move about the cleaned surface autonomously without user's control. The robot-vacuum cleaner contains obstacle sensor for detection of obstacle in the moving direction of the main vacuum cleaner body, rotation angle sensor for measurement of the main vacuum cleaner body rotation angle in real time scale, host for moving of the main vacuum cleaner body and controller for host direction for turning of the main vacuum cleaner body at detection of an obstacle by the obstacle sensor and for comparison of the full rotation angle measured by the rotation level angle with set control rotation angle for termination of host work when the full rotation level exceeds the control rotation level. If full rotation level exceeds the control rotation level the controller determines that the obstacle sensor is our of order. The control rotation angle is set by user by direct introduction of numerical value to the controller. Control mode of robot-vacuum cleaner stipulates control of the host for rotation of the main body of the vacuum cleaner at detection of obstacles by the obstacle sensor, measurement of the rotation angle of the main body of the vacuum cleaner in real time scale and comparison of the measured full rotation angle with the set control rotation angle with determination that the obstacle sensor got out of order when the full rotation angle exceeds the control rotation angles and thus termination of host work is provided.

EFFECT: robot-vacuum cleaner may autonomously detect sensor failure, inform user about it and exclude continuous rotation of the robot-vacuum cleaner body till the moment of complete termination of its power supply.
