Patent number: 9357894Abstract: A mobile robotistic mopping machine is formed of a body frame, a mop cloth, a power device, and a control device. The power device includes two opposite wheels and two opposite motors connected with the respective wheels for driving the wheels to rotate to further enable the body frame via the wheels to make the mop cloth move forward for cleaning the ground. The control device is electrically connected with the motors for controlling the motors. When the body frame makes the mop cloth move forward for a predetermined distance, the control device can control and make one of the motors reversely rotate and meanwhile make the other keep normal rotation to further enable the body frame to make the mop cloth turn for a predetermined angle and then keep moving forward.Type: GrantFiled: February 3, 2014Date of Patent: June 7, 2016Assignee: EGENPOWER INC.Inventors: Yao-Hsi Chiu, Fei-Yun Zhu
