Amazon's New Delivery 'Dogs on Wheels' Can Climb Stairs
Amazon Bets on Robotic 'Skateboarding Dogs' for Last-Mile Delivery
In a move that could revolutionize urban package delivery, Amazon has snapped up Zurich-based robotics company Rivr and its team of stair-climbing robotic couriers. The acquisition puts Amazon at the forefront of solving one of logistics' toughest challenges: getting packages up those final steps to customers' doors.
Meet the Delivery Dogs That Rollerblade
Rivr's signature invention isn't your average delivery bot. Picture this: a four-legged robot wearing what looks like roller skates. CEO Marko Bjelonic fondly calls them "dogs on wheels" - combining a quadruped's ability to handle uneven terrain with wheels' efficiency on flat surfaces.

These hybrid machines can:
- Climb stairs like their biological counterparts
- Roll smoothly across sidewalks and roads
- Navigate curbs and other urban obstacles autonomously
"It's about giving our robots the best of both worlds," explained Bjelonic in a recent interview. "Legs for flexibility, wheels for speed."
Why Amazon Wanted These Robotic Athletes
The e-commerce giant didn't just stumble upon Rivr. Amazon's Industrial Innovation Fund had already invested in the startup's seed round back in 2024, signaling early interest in their unconventional approach.
Key figures behind the deal:
- $25 million total funding raised by Rivr pre-acquisition
- $100 million valuation at time of purchase
- 100 robots planned for deployment by 2026 (now likely to expand faster under Amazon)
The acquisition allows Amazon to integrate Rivr's technology directly into its massive logistics network rather than waiting for gradual commercial rollout.
From Austin Pilot to Global Rollout?
Before joining Amazon, Rivr had begun testing its technology with delivery company Veho in Austin, Texas. The pilot program demonstrated how these wheeled quadrupeds could handle real-world delivery challenges - particularly in dense urban areas where stairs and narrow pathways frustrate traditional delivery methods.
While financial terms remain undisclosed, industry analysts see this as a strategic play by Amazon to control more of the last-mile delivery process. As one logistics expert put it: "Whoever solves the 'front door problem' wins the home delivery race."
The technology aligns perfectly with Amazon's broader automation strategy, which includes drone deliveries and warehouse robotics. With Rivr's team now onboard, we might soon see these robotic couriers trotting (and rolling) through neighborhoods worldwide.
Key Points:
- Game-changing design: Quadruped robots with wheels combine mobility types
- Urban solution: Specifically targets stair navigation in cities
- Strategic buy: Builds on Amazon's existing investment in Rivr
- Scale advantage: Amazon can deploy faster than a startup could alone
