### Did You Know: Many Ways to Repeat

After the AI learned what it needed to from Navigation with the cyber:bot, you might have expected it to use a for… loop to repeat the same maneuver four times.  But instead, it repeated the forward-left maneuver four times!  It would be better to write it as shown here:

Do you think maybe Bing Chat can be prompted to do a better scripting job?

That's a pretty long script.  Couldn't you use a loop to get that done in fewer lines?

Yes, you can use a loop to make the script more concise. Here is a modified version of the script that uses a for loop to repeat the forward and right turn movements four times:

AI-generated code. Review and use carefully. More info on FAQ.

```from cyberbot import *
import time

# Define the duration of the forward and right turn movements
forward_duration = 1.25 # seconds
turn_duration = 0.85 # seconds

# Repeat the forward and right turn movements four times
for i in range(4):
# Roll forward for 1250 ms
bot(18).servo_speed(75) # Left wheel counterclockwise
bot(19).servo_speed(-75) # Right wheel clockwise
time.sleep(forward_duration)

# Rotate right in place for 850 ms
bot(18).servo_speed(75) # Left wheel counterclockwise
bot(19).servo_speed(75) # Right wheel counterclockwise
time.sleep(turn_duration)

# Stop the servos
bot(18).servo_speed(None)
bot(19).servo_speed(None)```

This script defines the duration of the forward and right turn movements using variables, then uses a for loop to repeat the movements four times. The range(4) function generates a sequence of numbers from 0 to 3, which are used as the loop variable i. The loop repeats the forward and right turn movements four times, then stops the servos.

I hope this helps!

• Once again, save a copy of your current work.
• Rename your script ai-forward-right-stop-loop, and replace the text with the new chatbot script provided above.
• Connect the cyber:bot, run the script, and verify that it works.
• If you have access to Bing Chat, try your hand at making it write a script.  Be as descriptive as you can in your initial request to make it write the script in one or two iterations instead of three.
