附件是一个将机器人移动到特定距离的代码,但是我希望它在接近和障碍物时停止移动。我该怎么做呢?我尝试添加超声波来检测障碍物。我正在使用 nxt-python
def move_to(brick, bx, by ,rx, ry):
wheel_circumference = (pi * wheel_diameter)
distance_per_turn = (wheel_circumference / 360)
distance = math.sqrt((math.pow((bx - rx),2)) + (math.pow((by - ry),2)))
rotations = ((distance / distance_per_turn) / 360)
tacho_units = (round((rotations) * 360))
both.turn(power=power, tacho_units=tacho_units, brake=False)
if(ultrasonic.get_sample() < 20):
both.brake()
def activate2():
update_coordinates()
bx,by = get_ballxy()
rx,ry,a = get_robotxya()
if(ultrasonic.get_sample() < 15):
both.turn(power=-65, tacho_units=380, brake= False)
time.sleep(1)
turn_to(brick,bx,by,rx,ry,a)
time.sleep(0.5)
move_to(brick,bx,by,rx,ry)
kickBall(brick,by,ry)
Thread(target=update_coordinates).start()
connect()
update_coordinates()
while True:
#activate()
activate2()
time.sleep(3)
