One would assume that a robotic body would have devices and supplement cartridges for that, automatically monitored and regulated. The human body is a machine - but a robotic version would be actually optimally designed, rather than an endless variety of useful accidents. Even better, you can move the brain into different vessel shapes, each built for a particular purpose.

In any case, converting a fleshy brain's memories into an computerized format would be preferable. Unfortunately, I suspect that is hard to pull off without being lossy or fatal.
