Method of controlling motion of mobile warning triangle and mobile warning triangle applicant in the method thereof

A mobile warning triangle comprising:

• a warning triangle;
• at least two wheels;
• a sensor;
• at least one processor;
• and
• a storage device storing one or more programs which when executed by the at least one processor, cause the at least one processor to:
• control the mobile warning triangle to move forward and acquire color information detected by the sensor when the mobile warning triangle is placed on a road and the sensor detects a lane marking of the road;
• determine whether the color information detected by the sensor is a color of the lane marking;
• control the mobile warning triangle to continue moving forward if the color information detected by the sensor is the color of the lane marking;
• obtain first orientation information of a central axis of the mobile warning triangle and rotate the central axis of the mobile warning triangle to a first direction by a first predetermined angle if the color information detected by the sensor is other than the color of the lane marking;
• rotate again the central axis of the mobile warning triangle to a second direction by a second predetermined angle if the sensor does not detect the color of the lane marking during the rotating of the mobile warning triangle to the first direction by the first predetermined angle;
• control the mobile warning triangle to stop rotating the central axis and obtain second orientation information of the central axis of the mobile warning triangle if the sensor detects the color of the lane marking during the rotating of the mobile warning triangle to the second direction by the second predetermined angle;
• calculate a first deflection angle based on the first orientation information and the second orientation information of the central axis of the mobile warning triangle;
• and
• rotate again the central axis of the mobile warning triangle to the first direction by twice the first deflection angle and control the mobile warning triangle to continue moving forward.
