Mostly latency. But even if a single robot could be driven by a data centre consider the energy and hardware investment requirements to make such a creature practical.
The Figure robots use a two level control scheme with a fast LLM at 200Hz directly controlling the robot and a slow planning LLM running at 7Hz. This planning LLM could be very far away indeed and still have less than 142.8ms of latency.
