Freescale of Shanghai University was founc in 2006,supersonic Cavaliers, team RacerX, mad mouse team, S.U.L. Challenge team and other teams included.In the first time for competition,strive team and innovation team,using photoelectric and CCD seperately,completed the game model,including hardware production and algorithm debugging,in limit time and finally won the thrid prize. From then on,the third and forth competitions, we act outstandingly.
CCD Team
CCD team is also called camera team, the intelligent car use a digital or analog cameras as a sensor to detect the track information, to acquire gray information of the circuit, and then make corresponding measures.Because of the continuous signal that the camera acquired, the car can deal with vorious of complicated tracks,which making it the fastest car in three types of intellegent car,also the most worth watching car.
Photoelectric Team
Photoelectric intelligent car use an infrared sensor or a laser sensor to detect the track information, and judge the track information and thus make the corresponding countermeasure through receiving parts of the light reflected. Because of the disadvantages that infrared sensor emitting light divergence easily and the transmit power is insufficient, there is nobody ues it now basicly.
Electromagnetic Team
Electromageneric team is added in the Fifth Chinese University intelligent car competitions, .The cars must be able to detect the path through electromage field which generated by the wire with 100mA alternating current in the center of the track. According to the Maxwell theory.there will be alternating electromagnetic field generated around where alternating current exist. The alterating current frequency of the path navigation for the intellegent car is 20kHz, generating a VLF electromageneric whose frequency is between the power frequency and low frequency,about3kHz~30kHz.
Wind Wheel,which only cost 25 days for our design and completation,performed excellently in the competition of Bosch Power Tools.
