Question for picrawler command

I understand by looking up documents to use picrawler.
However, I saw the command turn left angle, turn right angle in the command do_action, and I wonder what is the difference between turn left and turn right.

I’m leaving a question here because I don’t think there’s a detailed explanation.

The difference between a left turn and a right turn is that they work in opposite directions.
With a left turn, the rudder will rotate to the left so that the spider turns left as a whole; then the opposite is true with a right turn.
