Robótica para infantil

Se puede hacer un robot tipo Beebot, Colby, Escornabot.
Si no conocéis estos robots mirar el curso de Aularagon

Podemos cargar el siguiente programa, modificado de https://github.com/arduino/arduino-alvik-mpy/blob/main/examples/touch_move.py

from arduino_alvik import ArduinoAlvik
from time import sleep_ms
import sys

alvik = ArduinoAlvik()
alvik.begin()

alvik.left_led.set_color(1, 0, 0)
alvik.right_led.set_color(1, 0, 0)

distancia = 15

movements = []


def blink():
    alvik.left_led.set_color(1, 0, 1)
    alvik.right_led.set_color(1, 0, 1)
    sleep_ms(200)
    alvik.left_led.set_color(1, 0, 0)
    alvik.right_led.set_color(1, 0, 0)

    global movements

    if alvik.get_touch_up():
        movements.append('forward')
        blink()
        while alvik.get_touch_up():
            sleep_ms(100)

    if alvik.get_touch_cancel():

        for i in range(0, 3):
            val = i % 2
            alvik.left_led.set_color(val, 0, 0)

        alvik.rotate(90, blocking=False)
    if movement == 'right':
        alvik.rotate(-90, blocking=False)
    while not alvik.get_touch_cancel() and not alvik.is_target_reached():
        alvik.left_led.set_color(1, 0, 0)
        alvik.right_led.set_color(1, 0, 0)
        sleep_ms(100)
        alvik.left_led.set_color(0, 0, 0)
        alvik.right_led.set_color(0, 0, 0)
        sleep_ms(100)

while alvik.get_touch_ok():
    sleep_ms(50)

while not (alvik.get_touch_ok() and len(movements) != 0):
    add_movement()
    sleep_ms(50)

try:
    while True:
        alvik.left_led.set_color(0, 0, 0)
        alvik.right_led.set_color(0, 0, 0)
        for move in movements:
            run_movement(move)
            if alvik.get_touch_cancel():
                break

        movements = []

        while not (alvik.get_touch_ok() and len(movements) != 0):
            alvik.left_led.set_color(1, 0, 0)
            alvik.right_led.set_color(1, 0, 0)
            alvik.brake()
            add_movement()
            sleep_ms(100)
except KeyboardInterrupt as e:
    print('over')
    alvik.stop()
    sys.exit()

El resultado es que perfectamente se puede usar como robótica en infantil
Los robots Beebot, Colby, Escornabot. utilizan la distancia de 15cm de desplazamiento, justo lo mismo que los palos depresores de lengua, luego fácilmente uno puede hacer un circuito :
