Method of controlling motion of mobile warning triangle and mobile warning triangle employing method

A mobile warning triangle comprising:

• a warning triangle;
• at least two wheels;
• a first sensor;
• a second sensor;
• at least one processor;
• and
• a storage device storing one or more programs which when executed by the at least one processor, causes the at least one processor to:
• control the mobile warning triangle to move forward and acquire first color information detected by the first sensor and second color information detected by the second sensor when the mobile warning triangle is placed on a lane and the first sensor detects a lane marking;
• determine whether the first color information detected by the first sensor is a color of the lane marking;
• control the mobile warning triangle to continue moving forward when the first color information detected by the first sensor is the color of the lane marking;
• determine whether the second color information detected by the second sensor is the color of the lane marking when the first color information detected by the first sensor is not the color of the lane marking;
• and
• correct a moving direction of the mobile warning triangle to a first direction by a first predetermined angle to continue moving forward when the second color information detected by the second sensor is the color of the lane marking.
