I know old age brings on memory loss, but this is strange. I thought flash memory code should be retained a long time, but after several months storage due to traveling and moving, I fired up Robonova and first thing, the battery pack was dead. After getting the batteries resolved, there was absolutely no code inside RN's memory. After refreshing memory code, everything is back to normal again. Apparently these humanoids are more real than we expect, as they say age can bring on memory loss. Can there be any other explanation?

Oh great ! another defect to worry about, I thought the robots were going to be immortal, now we know they loosen thier screws, fry thier servos, and eat thier batteries all while loosing what little brains we can give them. Sounds like we're more alike than not. RN-! was down six months while I worked another project, luckily it didn't do that,although a few screws did need retightening, have fun.

Normally they guarantee flash memory for 50 years or 100 years. We use microncontrollers extensively in ROV nodes and it is not uncommon for them to come back with corrupt or empty flash. It's not common enough here to be regarded as a problem so it's been ignored despite my protests. No research has been done in this area to my knowledge but I have a feeling that voltage surges and mechanical shock are prime suspects in these failures. Beware when we start flying planes and driving cars from microcontrollers, they may suddenly exhibit some strange behaviour!

Guys, very good replies! It certainly appears that mechanical shock caused the memory loss, but I cannot explain how this happens inside the flash memory IC chip. My RN was transported between Asian countries and undoubtedly received numerous mechanical vibration shocks while in luggage on various aircraft. Especially the jet landings - they create a big shock when the wheels first hit the runway! Well, you certainly have my attention in regard to this problem, and maybe we can enlist some of the flash memory chip experts for more details.
By the way, he's back to normal, being pampered, resting, and has retained all his memory since the refresh. As our humanoids become more and more complex, it seems they become more human-like. There is no doubt in my mind, that at some point in the future, they will become a new life form. Did I say in the future? hehe...
