Did some debugging on it today, in readiness for contacting support.

Predictably it wouldn't fault to start with, but I managed to get it to fault in the same way, once I'd run it for an hour or so.

Same failure:

- "help I'm stuck"
- check it, nothing blocking/tangled
- start it
- it backs up, turning left
- stops after a couple of seconds and says "help I'm stuck"

Checked/cleaned:

- laser
- drop sensors
- wall sensor

Tried to start it a few more times, same issue.

I don't think it can be the bumper switches themselves. If you press either of them in and try and start it, it knows they are pressed and refuses to start at all.

I power cycled it and then it would start and run normally. However I know from when it was faulting before that this doesn't always fix it, sometimes you can power cycle it and it still won't start.
