RIVR
Company Overview
RIVR (formerly known as Swiss-Mile) is a robotics and artificial intelligence company headquartered in Zurich, Switzerland. A spin-off from the Robotic Systems Lab at ETH Zurich, one of the world's leading technical universities, RIVR specializes in the development of "Physical AI"; advanced neural networks integrated into autonomous mobile robots.
The company has pioneered a unique hybrid robotic architecture that combines the efficiency of wheels with the agility of legs. This "wheeled-legged" design allows their robots to navigate complex urban environments: traversing sidewalks, climbing stairs, and entering buildings to automate the final stage of logistics, known as the "last mile."

The company is backed by high-profile global investors, including Bezos Expeditions (Jeff Bezos's investment firm) and the Amazon Industrial Innovation Fund, signaling strong industry validation of their approach to solving labor shortages and inefficiencies in the delivery sector.
Core Technology: Physical AI
RIVR differentiates itself from traditional robotics companies by its software-first approach. Rather than relying on rigid, hard-coded instructions, RIVR utilizes deep reinforcement learning to train its robots.
- General Physical AI: The robots are powered by neural networks that learn to move and interact with the world similar to how humans do. This allows the robot to adapt to unstructured environments, such as crowded sidewalks or snow-covered paths, without needing pre-mapped perfection.
- Sim-to-Real Transfer: RIVR trains its AI models in massive parallel simulations (digital twins) where the robot experiences millions of scenarios in a fraction of the time. These learned behaviors are then transferred to the physical robot, allowing it to master complex tasks like balancing on icy surfaces or navigating obstacles immediately upon deployment.
- Hybrid Locomotion: The control software manages the robot's unique ability to switch modes instantly. It drives on wheels for energy efficiency and speed on flat ground but engages its leg actuators to step over curbs, climb stairs, or stand upright to reach elevator buttons.
Products
RIVR ONE
The company's flagship product is RIVR ONE, an autonomous delivery robot designed to bridge the gap between the delivery van and the customer's doorstep.
- Form Factor: A quadrupeds (four-legged) robot equipped with motorized wheels at the end of each leg. This design offers the "best of both worlds": the speed of a car and the versatility of a walking creature.
- Performance:
- Speed: Capable of speeds up to 14 km/h (approx. 8.7 mph), significantly faster than typical walking-speed delivery bots.
- Range: Offers an operational range of over 30 km, allowing for extended shifts without frequent recharging.
- Payload: Can carry over 30 kg (approx. 66 lbs), suitable for parcels, groceries, and food orders.
- Navigation Capabilities:
- Stair Climbing: Unlike standard wheeled delivery bots that are stopped by a single step, RIVR ONE can climb full flights of stairs to deliver directly to a front door.
- Obstacle Negotiation: It can step over curbs, navigate uneven terrain, and adapt to changing surface friction (e.g., wet pavement vs. gravel).
- Safety & Interaction: The robot is equipped with LiDAR, cameras, and advanced perception systems to detect pedestrians and vehicles. It is designed to be "polite," yielding to humans and signaling its intentions.
Services and Solutions
RIVR offers its technology primarily to logistics providers, retailers, and smart city operators through flexible deployment models.
1. Last-Mile Delivery
This service automates the most expensive part of the shipping process, the final leg to the customer. RIVR robots can operate autonomously from local hubs (such as convenience stores or micro-fulfillment centers) to residential addresses.
* Doorstep Delivery: Because the robot can climb stairs and open unlocked gates, it provides true "doorstep" service rather than "curbside" service, which is a major differentiator in the market.
2. Van-Dispensed Delivery (Mothership Concept)
RIVR integrates its robots with traditional delivery vans to act as force multipliers for human drivers.
* Parallel Processing: Instead of a driver stopping the van, getting out, and walking to the door for every package, the driver can deploy a RIVR robot from the back of the van to handle one delivery while they handle another nearby.
* Efficiency: This approach increases the number of parcels a single van can deliver per hour, reducing the vehicle's idle time and the driver's physical fatigue.
3. Remote Operations & Support
RIVR provides a "human-in-the-loop" safety net. While the robots are autonomous, the company operates a 24/7 Remote Control Center. If a robot encounters a scenario it cannot resolve (e.g., a blocked path or a confusing construction site), a remote human operator can instantly take over, guide the robot through the difficulty, and then return control to the AI. This ensures high reliability and prevents robots from getting "stuck" in the field.
