10.4. Sample code#

from cutebot import *

# Create a sample for Cutebot category
cutebot = Cutebot()    

# While true, keep detecting the values received by the IR receiver
# Control the route of the Cutebot based on the received value
while True:
    Ir = cutebot.get_ir_value()
    if Ir == 14:
        cutebot.set_speed(50, 50)
    if Ir == 16:
        cutebot.set_speed(-30, 30)
    if Ir == 17:
        cutebot.set_speed(0, 0)
    if Ir == 18:
        cutebot.set_speed(30, -30)
    if Ir == 20:
        cutebot.set_speed(-50, -50)

Code details#

  1. Import the modules that we need for the program: cutebot module contains the classes and functions that operate on the Cutebot smart car.

from cutebot import *
  1. Create a sample for Cutebot category.

cutebot = Cutebot()
  1. While true, keep detecting the values received by the IR receiver.Control the route of the Cutebot based on the received value.

while True:
    Ir = cutebot.get_ir_value()
    if Ir == 14:
        cutebot.set_speed(50, 50)
    if Ir == 16:
        cutebot.set_speed(-30, 30)
    if Ir == 17:
        cutebot.set_speed(0, 0)
    if Ir == 18:
        cutebot.set_speed(30, -30)
    if Ir == 20:
        cutebot.set_speed(-50, -50)

10.5. Results#

After turning on the power, the Cutebot is controlled by IR remote control to drive.

10.6. Exploration#

Is it possible to control more functions of the Cutebot by IR remote control?
