As a lego RCX user I can assure that that wire is only power. These lego robots are miserable battery consumers. They go through batteries like they were made to. So you tend to find your self tethered all the time to save money.

Plus, the only way to communicate with the old RCX units is via infrared which only works within a couple of inches. So I assure you, it is autonomous.

I've been programming these things since they came out and this is definitely easily programmed.
