Key LastFeet Autonomous Delivery Field Report Findings

LastFeet Autonomous Delivery Field Report

Grayson Brulte joined LastFeet founder Lee Redden in Palo Alto and on the Stanford University campus to evaluate the company’s autonomous last-50-foot delivery robot, Boxer. Across multiple live delivery demonstrations in residential neighborhoods, Boxer proved capable of handling real-world obstacles, including stairs, garden paths, lawn debris, and pets or custom van modifications.

LastFeet Robot Capabilities and Terrain Navigation

During field testing across various residential homes, Boxer demonstrated autonomy from van departure to package drop-off. The robot navigated garden bends, grass, garden hoses, shoes, and Halloween decorations before ascending multi-step porch staircases. Upon reaching the doorstep, Boxer gently bowed down to release the package.

In stress-testing on the Stanford campus and local parks, the robot traversed deep sand, tree stumps, fallen logs, curbs, fiber optic installations, power conduits, and long flights of stairs. Boxer is capable of tackling any staircases built to standard building codes.

Van Integration and Autonomous Docking

A core operational advantage of LastFeet is that it requires no vehicle retrofitting. Boxer operates out of existing, standard delivery vans. Upon returning from a delivery, the robot aligns itself with the van door, climbs inside autonomously, lays flat/sits down for transit, and stays secure as the driver moves to the next destination.

Under the Hood: Perception and Simulation Training

Boxer’s navigation relies on a comprehensive camera suite, including surround-view cameras and two dedicated downward-facing cameras focused on the ground. These downward cameras allow the perception system to identify stair edges and terrain changes to place each foot precisely.

To master complex physical maneuvers, LastFeet trained Boxer’s control algorithms through hundreds of thousands of physics simulations. This simulation training taught the robot its body geometry, sensor integration, and dynamic locomotion needed to coordinate four legs and four driven wheels across unpredictable terrain.

Business Strategy and Market Expansion

LastFeet is transitioning from prototype testing to commercial operations. The company’s initial commercial deployment market is package delivery in Palo Alto, California, with plans to expand to additional cities as technology refinements continue. While Palo Alto provides a temperate baseline, LastFeet designed the 4-leg, 4-wheel driven chassis specifically to maintain traction and mobility in harsh winter conditions and snow.
