The Avatar Economy

Are remote workers the brains inside tomorrow's robots?

Progress toward the "avatarization" of the economy has been limited by two technical factors that don't involve robotics at all. They are the speed of Internet connections and the latency involved in long-distance communication. Connecting a Thai worker to a robotic avatar in Japan with enough signal fidelity to carry out nonroutine work may be more difficult than engineering a cheap robotic chassis and related control systems.

How much bandwidth is enough? A "perfect" (just like being there) connection to a robotic telepresence system must accommodate a signal of 160 megabits per second. Theoretically, too, the distance between robot and worker shouldn't exceed 1,800 miles: any farther and the operator could get confused by the time lag as signals travel round-trip. Realistically, however, avatar workers can probably be effective janitors or doctors even if they are farther away and sensory fidelity is weaker. The VGo runs on Verizon's 4G network, for instance, and the U.S. military's drone-control facility in Italy is 2,700 miles from Afghanistan.
