In the mechanism, has made the improvement to the ordinary toy car, causes the car to change nimbly, and may realize the random angle curve and the free velocity migration in the design scope。s order, the entertainment and interactive is stronger. This car various part uses the modular design, between each module control section uses programmable micro processing to cry, may in not increase the system hardware in the situation conveniently to carry on the redevelopment to the article carried on the experiment to a car, the experimental result had indicated that, the speech recognition system distinguished in the low noise environment rate is very high, in the noise level high situation, the recognition rate had the car response is keen.
