I'm arm-chairing a bit. This is the type of problem I'd expect on a prototype, but not on a production level device - especially on a construction robot that will be clearly out in the weather.
It reads to me like they didn't properly spec/source components that were appropriate for the weather conditions these robots are likely to see. The fact that this issue was reproducible at refrigerator temperatures is even more shocking. 39F (taken from a photo) is not very cold.

- exmadscientist 4y agoSpeaking very broadly, because it's not all standardized and many companies have their own definitions, in degrees C: Range Min Max Commercial 0 to + 70 Industrial 0 to + 85 Automotive -40 to +105 Extended Automotive -40 to +125 Military -55 to +125 But that's for the parts themselves, and just working at that. Weird things can and do happen at temperature extremes. If you're very lucky, they're documented in datasheets/manuals. If you're lucky, they're known enough to be in white papers or industry presentations, or known to one of the companies that do this stuff for a living. If not... well, hope someone's heard of it, or you've got a huge testing budget....
