This impressive delivery robot will soon be arriving in a city in the U.S.

      Most delivery robots that operate on the streets are designed as small, wheeled vehicles with a secure compartment for carrying delivery items.

      However, a significant challenge for these machines is their inability to navigate obstacles such as stairs, uneven surfaces, or other difficult terrains, which prevents them from reaching a person's front door directly.

      Recognizing this gap, Swiss startup Rivr introduced Milo earlier this year, which can be described as a highly adaptable robotic dog — similar to Boston Dynamics' Spot — equipped with a compartment on its back for deliveries.

      While Milo also has wheels, its legs are remarkably flexible, allowing it to walk directly up or down stairs with ease.

      Rivr is targeting the last-mile delivery space for its intelligent, AI-driven robot and has announced plans to deploy Milo for commercial deliveries in Pittsburgh, Pennsylvania, early next year, with a partner — likely a parcel or food delivery service — to be revealed soon. The robot is currently being tested in the area under challenging conditions.

      In May, the company trialed Milo in Austin, Texas, where it successfully managed parcel deliveries between vans and residential doorsteps, using its built-in cameras and LiDAR technology for navigation. Recipients can unlock the compartment to retrieve their items, and if they are unavailable, the robot can place the item on the ground in front of their door.

      Milo has also participated in several pilot programs in the U.K. this year, picking up parcels from courier vans at the curb and delivering them directly to customers’ doorsteps.

      Testing of food deliveries using Milo took place in Zurich, Switzerland, demonstrating the robot's capability to navigate various obstacles.

      "The robot is designed to function in residential areas — not just on sidewalks," Rivr CEO Marko Bjelonic stated previously. "It detects its environment, adapts to different terrains, and can deliver straight to doorsteps, even in complex residential layouts."

      Milo's wheeled legs provide an advantage over typical compact delivery robots, which struggle due to their low-profile design.

      Rivr envisions Milo working alongside delivery drivers rather than replacing them, aiming to enhance delivery speed and alleviate driver fatigue.

      The company is now focusing on its trial in Pittsburgh as it continues to refine the technology for a broader rollout.
