以下是一个基本的麦克纳姆轮移动控制示例代码:
```
from Adafruit_MotorHAT import Adafruit_MotorHAT, Adafruit_DCMotor
# 创建一个MotorHAT对象
mh = Adafruit_MotorHAT(addr=0x60)
# 设置电机ID
motor_FL = mh.getMotor(1) # 前左轮
motor_FR = mh.getMotor(2) # 前右轮
motor_BL = mh.getMotor(3) # 后左轮
motor_BR = mh.getMotor(4) # 后右轮
# 设置最大速度(0-255)
MAX_SPEED = 150
# 定义4种运动方向
STOP = "stop"
FORWARD = "forward"
BACKWARD = "backward"
LEFT = "left"
RIGHT = "right"
# 定义计算速度的函数(角度、速度)
def calculate_speed(angle, speed):
radians = angle * 3.14 / 180 # 将角度转换为弧度
v_x = speed * math.cos(radians)
v_y = speed * math.sin(radians)
v1 = v_x - v_y
v2 = v_x + v_y
v3 = -v_x + v_y
v4 = -v_x - v_y
return v1, v2, v3, v4
# 运动控制函数
def move(direction, speed=MAX_SPEED):
if direction == STOP:
motor_FL.run(Adafruit_MotorHAT.RELEASE)
motor_FR.run(Adafruit_MotorHAT.RELEASE)
motor_BL.run(Adafruit_MotorHAT.RELEASE)
motor_BR.run(Adafruit_MotorHAT.RELEASE)
elif direction == FORWARD:
v1, v2, v3, v4 = calculate_speed(0, speed)
motor_FL.run(Adafruit_MotorHAT.FORWARD)
motor_FL.setSpeed(abs(v1))
motor_FR.run(Adafruit_MotorHAT.FORWARD)
motor_FR.setSpeed(abs(v2))
motor_BL.run(Adafruit_MotorHAT.FORWARD)
motor_BL.setSpeed(abs(v3))
motor_BR.run(Adafruit_MotorHAT.FORWARD)
motor_BR.setSpeed(abs(v4))
elif direction == BACKWARD:
v1, v2, v3, v4 = calculate_speed(180, speed)
motor_FL.run(Adafruit_MotorHAT.BACKWARD)
motor_FL.setSpeed(abs(v1))
motor_FR.run(Adafruit_MotorHAT.BACKWARD)
motor_FR.setSpeed(abs(v2))
motor_BL.run(Adafruit_MotorHAT.BACKWARD)
motor_BL.setSpeed(abs(v3))
motor_BR.run(Adafruit_MotorHAT.BACKWARD)
motor_BR.setSpeed(abs(v4))
elif direction == LEFT:
v1, v2, v3, v4 = calculate_speed(270, speed)
motor_FL.run(Adafruit_MotorHAT.BACKWARD)
motor_FL.setSpeed(abs(v1))
motor_FR.run(Adafruit_MotorHAT.FORWARD)
motor_FR.setSpeed(abs(v2))
motor_BL.run(Adafruit_MotorHAT.FORWARD)
motor_BL.setSpeed(abs(v3))
motor_BR.run(Adafruit_MotorHAT.BACKWARD)
motor_BR.setSpeed(abs(v4))
elif direction == RIGHT:
v1, v2, v3, v4 = calculate_speed(90, speed)
motor_FL.run(Adafruit_MotorHAT.FORWARD)
motor_FL.setSpeed(abs(v1))
motor_FR.run(Adafruit_MotorHAT.BACKWARD)
motor_FR.setSpeed(abs(v2))
motor_BL.run(Adafruit_MotorHAT.BACKWARD)
motor_BL.setSpeed(abs(v3))
motor_BR.run(Adafruit_MotorHAT.FORWARD)
motor_BR.setSpeed(abs(v4))
# 停止电机
move(STOP)
```
