Virtual instruction set

Hello.

I am thinking about simulating robots in a virtual world, and they would have an embedded computer that controls their movement.

I would like to know which instruction set architecture to simulate on said computers. Also, if I use an instruction set already supported by common compilers, will I be able to compile C code and load the resulting binaries on these virtual robots ?

Thank you.

Well, I plan on doing a fully safe and enclosed thing. I don’t want robots to be able to crash the whole system, corrupt memory, or go into an infinite loop, no matter what their code is.
In the worst case, they’d crash their own robot.
Define the interface via some RPC or protocol then - any language written anywhere, running anywhere (remotely or locally) could then use it. Although, this might be complicating things if there's a lot of traffic and you need efficiency.
