這個機(jī)器狗由STM32F103C6T6為核心接有四個SG90舵機(jī)和一片BT04-E藍(lán)牙模塊構(gòu)成.由于機(jī)器狗每條腿只有一個自由度,所以無法優(yōu)化步態(tài)程序及重心控制.機(jī)器狗行走時只會在在原地徘徊.為了能使機(jī)器狗正常行走,就在其腳上裝配了棘輪裝置,使其向前磨擦力小于向后磨擦力.
手機(jī)遙控采用HC藍(lán)牙助手APP來控制機(jī)器狗前進(jìn),左轉(zhuǎn),右轉(zhuǎn),停止四種工作狀態(tài).
機(jī)器狗 程序如下:
#include <Servo.h>
Servo myservo1;
Servo myservo2;
Servo myservo3;
Servo myservo4;
char seria1Data;
int k = 0;
int pos = 0;
void setup() {
Serial.begin(9600);
myservo1.attach(PA0);
myservo2.attach(PA1);
myservo3.attach(PA2);
myservo4.attach(PA3);
myservo1.write(90);
myservo2.write(90);
myservo3.write(90);
myservo4.write(90);
delay(2000);
}
void loop() {
seria1Data= Serial.read();
if(seria1Data == '1' ) k=1;
if(seria1Data == '2' ) k=2;
if(seria1Data == '3' ) k=3;
if(seria1Data == '0' ) k=0;
if(k == 3 ) {
for (pos = 60; pos <= 120; pos += 1) {
myservo1.write(pos);
myservo2.write(180-pos);
myservo3.write(pos);
myservo4.write(180-pos);
delay(10);
}
for (pos = 120; pos >= 60; pos -= 1) {
myservo1.write(pos);
myservo2.write(180-pos);
myservo3.write(pos);
myservo4.write(180-pos);
delay(10);
}
}
if(k == 1 ) {
myservo1.write(60);
myservo2.write(120);
for (pos = 60; pos <= 120; pos += 1) {
myservo3.write(pos);
myservo4.write(180-pos);
delay(10);
}
for (pos = 120; pos >= 60; pos -= 1) {
myservo3.write(pos);
myservo4.write(180-pos);
delay(10);
}
}
if(k == 2 ) {
myservo4.write(60);
myservo3.write(120);
for (pos = 60; pos <= 120; pos += 1) {
myservo1.write(pos);
myservo2.write(180-pos);
delay(10);
}
for (pos = 120; pos >= 60; pos -= 1) {
myservo1.write(pos);
myservo2.write(180-pos);
delay(10);
}
}
if(k == 0 ) {
myservo1.write(90);
myservo2.write(90);
myservo3.write(90);
myservo4.write(90);
}
}
