HULK service was still running.

Cameras seem to exist, maybe the camera reconnection did not work correctly?

This is probably caused by the new nao_camera crate that got rewritten for Framework v2. Probably it should catch some errors and try to reconnect the camera instead of throwing an error to our framework.

Nevertheless we should check why this happens that often. I heard that even slight vibrations cause these errors. We should check whether a connector is loose or broken and whether we need to hand the NAO in for repair.

How was this issue fixed?

[oleflb]

This behavior was not observed anymore in Bordeaux/Leipzig or Rome

[h3ndrk]

My intention back then was to keep this issue open to reevaluate the resetting of the cameras. 🤔

This seems to be resolved ;)
