1. An auto-redirecting robot, comprising:
- a main body;
a control module, wherein said control module is disposed in the main body;
a plurality of driving modules, wherein the plurality of driving modules are disposed in the sides of the main body, characterized in that the control module directs the plurality of driving modules, so that the plurality of driving modules guide the main body to move alongside an obstacle;
a plurality of signal transmitters, wherein the plurality of signal transmitters are disposed in the sides of the main body, characterized in that the plurality of signal transmitters keep sending out signals to the obstacle as the main body is moving alongside said obstacle;
a plurality of signal receivers, wherein the plurality of signal receivers are disposed in the sides of the main body, characterized in that the plurality of signal receivers receive bounced-back signals from the obstacle; and
two sensors, wherein the two sensors are disposed in two-sides of the main body respectively, characterized in that as the main body touches the obstacle and one of the sensors is activated, the control module redirects the plurality of driving modules for moving said main body away from the obstacle;
wherein the control module generates a signal characteristic change based on the bounced-back signals received by the plurality of signal receivers,and characterized in that the control module generates a signal standard value based on said signal characteristic change and determines a keep-away distance based on the signal standard value,and characterized in that the control module controls the plurality of driving modules for keeping said keep-away distance between the main body and said obstacle while the main body moves alongside the obstacle, so that the main body needs not to touch the obstacle repeatedly; and
wherein if properties of said obstacle change or the bounced-back signals are inconsistent with the signal standard value, the control module directs the plurality of driving modules for moving the main body towards the obstacle until one of the two sensors is activated by the obstacle, then the control module directs the plurality of driving modules for moving the main body away from the obstacle.

Abstract
An auto re-directing robot able to adjust its moving paths automatically and a method thereof are disclosed in present invention. The auto re-directing robot has a control module, which may generate a signal standard value according to the bounced-back signals from an obstacle. Then, the control module determines a keep-away distance between the robot and the obstacle. In the case, the robot needs not to touch the obstacle repeatedly for determining whether it should change its moving path. In addition, when the robot encounters obstacles with different properties, the robot can adapt to change its paths automatically based on the properties of the obstacles.
