Let’s Fight! Warrior!

Here, PiSloth is a brave warrior, when it appears in front of the enemy, it will let out a roar and rush to the enemy.

Note

You can download and print the PDF Cartoon Mask for your PiSloth.

Run the Code

cd ~/pisloth/examples
sudo python3 lets_fight.py

After the code is run, PiSloth will continuously detect the distance of the obstacle, when the distance is between 5 and 40, PiSloth will make a roaring sound and rush forward; when the distance of the obstacle is less than 5, PiSloth will stop.

Code

Note

You can Modify/Reset/Copy/Run/Stop the code below. But before that, you need to go to source code path like pisloth\examples. After modifying the code, you can run it directly to see the effect.

from pisloth import Sloth
from robot_hat import Music
from robot_hat import Ultrasonic
from robot_hat import Pin
import time
import os


music = Music()

sloth = Sloth([1,2,3,4])
sloth.set_offset([0,0,0,0])
sonar = Ultrasonic(Pin("D2") ,Pin("D3"))

alert_distance = 40
contact_distance = 5

def main():
    distance = sonar.read()
    if distance <= alert_distance and distance >= contact_distance :
        try:
            music.sound_effect_play('./sounds/battle.wav')
            music.background_music('./musics/attack.mp3')
            music.music_set_volume(20)
        except Exception as e:
            print(e)
        while True:
            distance = sonar.read()
            print(distance)
            if distance < 0:
                continue
            if distance <= contact_distance:
                break
            sloth.do_action('forward', 1,90)
    sloth.do_action('stand', 1, 90)
    time.sleep(1)


if __name__ == "__main__":
    while True:
        main()

How it works?

Here is the main program.

• Read the distance detected by ultrasonic module and filter out the values less than 0 (When the ultrasonic module is too far from the obstacle or cannot read the data correctly, distance<0 will appear).

• When the distance is between 5 and 40, PiSloth will play warning.wav and attack.mp3 and move forward.

• When the distance is less than 5, PiSloth will keep the stand position.

distance = sonar.read()
if distance <= alert_distance and distance >= contact_distance :
    try:
        music.sound_effect_play('./sounds/battle.wav')
        music.background_music('./musics/attack.mp3')
        music.music_set_volume(20)
    except Exception as e:
        print(e)
    while True:
        distance = sonar.read()
        print(distance)
        if distance< 0:
            continue
        if distance<=contact_distance:
            break
        sloth.do_action('forward', 1,95)
sloth.do_action('stand', 1, 90)
time.sleep(1)

Note

You can add different sound effects or music to musics or sounds folder via Filezilla Software.
