>>> Speaking as someone who has been working in the medical device world, at least in America, the FDA doesn't allow cloud hosted surgical robots. You generally aren't even allowed any inbound connection. If the device has any network access it must reach out to a hard configured address then either push or pull data in a provable risk tested manner.

That's why you see those fanny pack chemo devices with multiple processors in them. Life risking functions are on one or more processors running an approved RTOS. Network communication of any kind has to have its own processor and RTOS.

One in particular is a Phd from Johns Hopkins trying to run a post-op clot monitor on an ordinary laptop running windows. If they somehow manage to bribe that through FDA approval, it will be on those late night 800-number lawyer commercials within weeks of shipping.

Is that anything like FAA approval for the Max 8 ???
