Travis Kalanick’s robotics startup Atoms may be preparing to make a major move into autonomous vehicles, including potentially the growing robotaxi market.

The company recently raised $1.7 billion in funding led by Andreessen Horowitz, giving it significant resources to expand its team and pursue acquisitions. While Atoms has remained relatively quiet about its long-term plans, new reporting suggests autonomous transportation could become an important part of its strategy.

According to the Financial Times, Atoms has discussed its robotaxi technology with Uber, including how the ride-hailing company could potentially use it. Uber has also invested $100 million in Atoms, strengthening the connection between the two companies.

Atoms’ direction also follows its acquisition of Pronto, an autonomous mining company led by Anthony Levandowski, Uber’s former self-driving chief.

Robotaxis reportedly aren’t the entire focus of Atoms, but the company’s growing investment in autonomous technology suggests it could become a significant new player in the industry.

For Kalanick, the move could represent a return to the autonomous-transportation space — and potentially another chapter in his long-running relationship with Uber.
