Patent number: 7402974Abstract: Disclosed herein is a device for detecting lift of an autonomous mobile robot. The device comprises at least one detection unit to detect lift of the main body of the robot during driving of the robot and to generate and output the lift detection signal, and a controller to control driving of the robot, and to output the driving stop signal to a driving motor after generating a driving stop signal for stopping driving of the robot according to the lift detection signal transmitted from the detection unit. When the robot is lifted by a user, the device stops driving of the motor in response to the lift of the robot, thereby eliminating additional operation of the user to stop driving of the robot as well as protecting the user.Type: GrantFiled: December 12, 2005Date of Patent: July 22, 2008Assignee: LG Electronics Inc.Inventor: Hyeong-shin Jeon

Publication number: 20060259212Abstract: Disclosed is a mobile robot, wherein obstacles are efficiently sensed by combining obstacle sensing signals output from different sensing units having different sensing areas and thus a drive of the mobile robot is controlled to avoid the obstacles. The mobile robot according to the present invention comprises a plurality of sensing units comprised of different sensors having different sensing areas for sensing obstacles in the traveling direction, and a microprocessor for outputting control signals according to avoidance instruction corresponding to a combination of sensing signals from the different sensors to avoid the obstacles. Accordingly, the present invention has an advantage that it is possible to recognize the obstacles with a high reliability and to avoid the obstacle efficiently, compared to when sensing the obstacles with a single kind of sensor.Type: ApplicationFiled: December 28, 2005Publication date: November 16, 2006Inventor: Hyeong-shin Jeon
