If you're sipping a Budweiser somewhere in Colorado Springs, Colo., you just might have a robot to thank for that thirst-quenching brew.

Last week, self-driving truck start-up Otto teamed with Anheuser-Busch to successfully deliver a semi-tractor full of beer from Fort Collins, through Denver and on to the southern Colorado city in the shadow of Pikes Peak.

For the majority of that 120-mile trip, the truck's driver left his seat and observed the road from the comfort of the sleeper berth. An Otto video of the drive shows the slightly disconcerting image of a massive 53-foot trailer filled with 2,000 cases of Bud rumbling down I-25 with no human in the cab.

Otto's tech is at present confined to highways, and humans take over in city traffic. Otto and Anheuser-Busch, which announced the news Tuesday, plan additional real-world autonomous truck drives in the months ahead.

"The initial appeal for us was to see how we could meet the needs of a company like Anheuser-Busch," Otto co-founder Lior Ron tells USA TODAY. "But now after this successful test, we're eager to see how it will handle other roads and other weather."
