Don't know exactly what you're getting at without more specifics, but
there shouldn't have to be any difference on the Erlang side.
If you'd use IDL to specify your API between Erlang and the outside,
you would get a well-defined interface. Then again, if you really want
high I/O throughput, you might want to compromise on generality...

You'd put the I/O part in a linked-in driver, and send user-friendly
messages to an Erlang process. What would be the typical
message-handling capacity requirement for various types of robot?
As far as the high-level power of VB for certain tasks, well, it's
simply a matter of resources, I guess. User-friendly prefab solutions
take time and money to develop, and there simply aren't that many
Erlang programmers around to do that... yet. (:
I don't know how VB components are best reused by Erlang hackers.
