Specifically, what isn't working? Is the steering doing nothing at all? Does it work if you make a simple program with only one car object? |

Yes, it doesn’t give any errors, but it doesn’t steer at all. I thought the issue might be the weight of the vehicle, but even when I lift it up, the steering motor doesn’t react to the left joystick at all. Everything was working with the program for four-wheel drive. At some point I also built a six-wheel vehicle using the same scheme and everything worked. This is a new model based on the same principle, but for some reason it doesn’t want to turn at all. (Everything is definitely connected correctly.) And when you start it, the steering motor, as usual, performs the test movement several times to the right and left.) Bur aftre that it doesn’t steer at all. |

Was it using the same program? |

No, I rebuilt the vehicle a bit, so I decided to rewrite the program from scratch. Interestingly, the old program also stopped working. Do you see any mistake in the code of the new program? Thank you for trying to help. |

Good to know it was working before. I just had a bit of a deja vu moment. What fixed it last time? |

Last time, what helped was “unplugging and plugging back in every cable” and writing the same program again from scratch, repeating it step by step. This time I tried that too. Last time it did show an error, and the steering motor didn’t do the initial test turns at startup. This time it’s different. And the program I posted now—I also rewrote it from zero to solve the problem, but it didn’t help. I don’t understand what the issue is. :( |

I went ahead and reproduced it. It works for me. Which port is your steering motor plugged into? (please check the cable, not the program). Are you using Pybricks Beta? This version has some problems with the Xbox Controller so it is better to use the stable version at https://code.pybricks.com/ |

I built a 6-wheel vehicle — a 6×6 car.
The steering principle was the same as for a 4×4. Since the “car with steering and drive” module doesn’t allow adding more than two motors, I simply duplicated the module and added new motors. So I ended up with “carA with steering and drive” and “carB with steering and drive.”
Everything worked fine with four motors. Now it doesn’t show any errors. After starting the program, in test mode the steering motor even turns left and right a couple of times. But when the car is actually driving, the steering doesn’t work at all.
Even though the principle is absolutely the same as before.
Where is the mistake?
Is there some other way to add one steering motor and five drive motors to a car?
