thx for the quick response. Somehow it actually worked afterwards. I thought i had checked it before properly.

Hello,
after having a talk with a awesome coworker of RoboLink we were finally able to update to 2.31.
Now I tried to work with the camera.

When starting drive mode it shows: "Camera may not be connected"

When trying the QR-Code-Course for example and trying to start the camera it shows the following message:
Starting PiCamera

PiCameraMMALError Traceback (most recent call last)

461 "and ensure that the camera has been enabled.")
462 else:

PiCameraError: Camera is not enabled. Try running 'sudo raspi-config' and ensure that the camera has been enabled.

I already tryed it like 3 times and also checked the camera cables on the board.

Hello,

me and a fellow student are working on a project with Zumi.

We both have Version 2.02 and are trying to update to version 2.31.
Now when we update via online interface the Zumi-screen-progressbar stops at like 93%
and stays there until Zumi is out of charge.

What do we do

So im working on a study project with my Zumi.
First I need to create a own line Follower.

I tried to get used to the IR-Sensors in small steps
but this code doesnt work.

from zumi.zumi import Zumi
from zumi.util.screen import Screen
import time

zumi = Zumi()
screen = Screen()

zumi.reset_drive()
for i in range(0, 100):
zumi.forward_step(20,0)
ir_readings = zumi.get_all_IR_data()
screen.draw_text(str(ir_readings[3]))

zumi.stop()

If i run the code zumi is driving for a bit then making quick turns in the same spot left and right and
shuts off comletly.

Hello,
is there any other way to use code on Zumi like in Jupyter.

I Would like to classicly programm with visual studio code or something.
Like using modules etc. and having an normal IDE instead of using Jupyter.
Is this possible.

Greetings
