Now artificial intelligence is very hot, face recognition, voice recognition control are all part of the voice recognition technology now has some mature programs, such as the traditional LD3220, as well as the voice recognition of the University of Science and Technology, also Baidu's DuerOS, this car is The LD3220-based speech recognition module performs DIY. Let's take a picture of the whole. Below is the DIY installation section. Parts of the chassis of the car. Two wheels close-up. The diagram of the chassis assembly is completed. Small car top view. Side view of the trolley - the oversized wheels are particularly conspicuous. The space above is very good, so I want to toss how to toss. Let me talk about my control system. powered by: Millet charging treasure 10000MAh, output 2A Control System: STM32F103+LD3220 speech recognition module drive: L298N motor drive module Briefly introduce the system's workflow: Through the LD3220 to set the keyword speech recognition, identify a certain signal to the STM32, the MCU judges the different signals, and jumps to the L298N to output different control levels, driving the two motors to advance / Back/left turn/right turn/stop. L298N motor drive module Finally, a installation diagram of the control electronic system Keep tossing, stay young, and everyone is going to toss DIY!
