Human brains aren’t limited to the standard human body plan. People born with an extra finger have no issues operating that finger just as well as people with the normal complement of fingers. Animal experiments have pushed this quite far.

If your AI has an issue because the robot has a different body plan, then no it’s not AGI. That doesn’t mean it needs to be able to watch every camera in a city at the same time, but you can use multiple AGI’s.
