Many businesses are considering different plans to make automotive artificial intelligence 1)_______.
The 2) _______ of Argo AI – along with automaker partners Ford Motor Company and Volkswagen AG - believe their plan will work. It is different from those of some of their more highly valued rivals.
Argo AI wants to get customers that will use robot vehicles for many purposes, including 3) _______ goods and people.
Background and business plan
Bryan Salesky, the leader of Argo AI, started developing automated vehicles 12 years ago, in a competition.
The self-driving systems developer is now at the center of a 4) ______________. Argo AI and its partners think that self-driving vehicle technology must be good for more than just replacing taxi drivers.
"I hate the word robotaxi," Salesky said in a rare interview at Argo's Pittsburgh headquarters. "There are so many applications and businesses to be built."
A 5)________ deal is at the heart of The Argo business plan. Ford and VW will pay Argo fees based on the distance traveled by vehicles equipped with Argo's technology. Details of that deal have not been reported until now, notes the Reuters news agency.
Among the possible uses of Argo's technology: Long-distance trucking for e-commerce.
Argo's plan is to provide self-driving systems that Ford will launch in late 2021 in three U.S. cities.
VW leaders told Reuters they expect to follow in 2022 or 2023 with a VW-designed 6) ___________vehicle.
Competition
Some rivals are not persuaded that Argo has any lead.
Glen De Vos is chief technology officer of Aptiv, which recently bought self-driving startups nuTonomy and Ottomatika.
He noted Aptiv's partnership with the 7) __________company Lyft. He said the companies are testing self-driving vehicles, and added that Argo "doesn't have the 8)____________ that Aptiv has."
Investors so far see less value in Argo than companies whose work centers on robotaxis. For example, the company Waymo is valued at $105 billion. Another, Cruise, is valued at $19 billion.
Argo's value is estimated at $7.25 billion following Volkswagen's $1.9 billion investment.
