Code
Note: You can Modify/Reset/Copy/Run/Stop the code below. But before that, you need to go to source code path
like picrawler\examples. After modifying the code, you can run it directly to see the effect.
from picrawler import Picrawler
from time import sleep
from robot_hat import Music
from vilib import Vilib
crawler = Picrawler([10,11,12,4,5,6,1,2,3,7,8,9])
#crawler.set_offset([0,0,0,0,0,0,0,0,0,0,0,0])
music = Music()
def main():
Vilib.camera_start()
Vilib.display()
Vilib.color_detect("red")
speed = 100
while True:
if Vilib.detect_obj_parameter['color_n']!=0:
coordinate_x = Vilib.detect_obj_parameter['color_x']
music.sound_effect_threading('./sounds/talk1.wav')
if coordinate_x < 100:
crawler.do_action('turn left',1,speed)
sleep(0.05)
elif coordinate_x > 220:
crawler.do_action('turn right',1,speed)
sleep(0.05)
else :
crawler.do_action('forward',2,speed)
sleep(0.05)
else :
crawler.do_step('stand',speed)
sleep(0.05)
if __name__ == "__main__":
main()
