RIVR Delivery Robot (formerly Swiss-Mile)
RIVR is the commercial delivery robot developed by the team formerly known as Swiss-Mile, a spin-out from ETH Zurich's robotics research programme. The platform was rebranded RIVR ahead of its March 2026 acquisition by Amazon.
Hybrid Locomotion Architecture
RIVR's core engineering innovation is its hybrid locomotion system: four wheeled legs that can roll efficiently on flat surfaces (roads, pavements, warehouse floors) and transition to dynamic legged locomotion to navigate steps, kerbs, and uneven terrain. This hybrid approach addresses the fundamental limitation of pure wheeled delivery robots, which cannot handle the last few metres of most residential deliveries.
Amazon Acquisition
Amazon acquired RIVR in March 2026 alongside Fauna Robotics, signalling a dual investment in last-mile ground delivery and home robotics intelligence. Integration with Amazon's logistics network and Prime delivery infrastructure is anticipated.
Deployment Context
RIVR is positioned to complement drone delivery (Amazon Prime Air) for routes or conditions where aerial delivery is impractical, providing a ground-based autonomous alternative capable of delivering directly to front doors.
FAQ
What is the relationship between RIVR and Swiss-Mile?
RIVR is the rebranded commercial entity of Swiss-Mile, an ETH Zurich spin-out that developed the hybrid wheeled-quadruped locomotion platform. The rebrand occurred ahead of the March 2026 Amazon acquisition.
Why did Amazon acquire RIVR?
Amazon acquired RIVR to accelerate last-mile ground delivery capability, complementing Prime Air drone delivery with a ground robot capable of navigating residential environments and delivering directly to doorsteps.
