Function Calling Enables Language Models To Actuate Robots

Travis demonstrates a small TARS replica that uses function calling to translate speech into structured commands, which an executor layer validates and runs on motors and services. The article explains function calling's mechanics, executor responsibilities, and trade-offs, noting typical latencies from hundreds of milliseconds to several seconds and power draws in the tens of watts. It warns designers to balance autonomy, safety, and cost when exposing tools to models.
