A self-tracking smart car has been designed based on infrared photoelectric sensor and speech recognition technology.The car adopts 16 bit singlechip SPCE061A of Sunplus Inc to work as the core processor of the control circuit

and obtains the path information by the reflected infrared photoelectric sensor.The car can adjust the direction and speed by the location of the black part of the path information to implement self-tracking.Compiled speech program API function to achieve speech capability of human-machine intercourse based on SPCE061A.Experiments indicates that the smart car can achieve the anticipated steady and credible purpose.The technic can use the fields such as physical disabilities smart wheelchair

service robot

intelligent toy

unmanned driving vehicles

storage

etc.
