Johdanto

Testataan, jos useita ohjauslohkoja voidaan asettaa peräkanaa; toimii täydellisesti.

Robotti

Ideat ja periaatteet toimivat lähes kaikille roboteille, mutta tämä on testattu Asimovilla.

Anturit

Ei antureita, paitsi servomoottorien.

Esimerkki

Teoriaa

Cascade a few .on() functions to steer first left then right. Sleep a few seconds in between the rounds.

An Example Code

#!/usr/bin/env python3
from ev3dev2.motor import MoveSteering, OUTPUT_B, OUTPUT_C
from time import sleep

#How about move steering?
steer_pair = MoveSteering(OUTPUT_B, OUTPUT_C)
steer_pair.on(steering=-20, speed=5)
sleep(10)
#steer_pair.off()

steer_pair.on(steering=20, speed=5)
sleep(10)

steer_pair.off()


Exercises

1. Make the robot to steer around a table or a chair. Try to stop it at the starting position

2. Make the robot stop

  1. After 10 seconds
  2. After 3.5 rotations of the left tire
  3. After the colour sensor finds a black tape.

3. Try different steering values:

  1. 0
  2. -50 and +50
  3. -100 and +100
  4. -110 and +110
