LastFeet Autonomous Delivery Field Report

Last Feet has built a quadruped robot named Boxer that autonomously delivers packages from a van to the front door, navigating stairs, sand, logs, curbs, and uneven terrain without any human intervention. The robot uses cameras—including two downward-facing cameras and simulation-based training across hundreds of thousands of runs to master stair climbing and rough terrain.

Founder Lee Redden says the first market is package delivery in Palo Alto, with plans to expand to other cities as the technology matures. According to the Field Report, Last Feet robot saves 25% of the time required to deliver a package to a door.

Introduction to Last Feet and the Last-50-Feet Problem

Grayson Brulte: We’re back in the field again. This time we’re visiting Last Feet. No, it’s not an autonomous vehicle, it’s a company that’s solving the last 50 feet autonomously. This is the field report. Here it is. Here’s the Last Feet robot. That’s right, the Last Feet robot is fully autonomous. And what is it trying to solve? The last 50 feet of delivery. In the future, an autonomous vehicle will pull up to your house, a Last Feet robot will get out, it’ll go over your hose, it’ll go through your grass, and even go around the corner, and watch this, it even goes up the stairsaAnd it avoids your Halloween decorations. And when it’s time, the robot gently bends down and delivers your package, all without any human intervention. Shoes? No problem for the Last Feet robot. It gently goes around them and down the stairs it goes. As it traverses your yard, you never know what you’re gonna find in the yard as it heads back to the van.

As the Last Feet robot approaches the van, it puts itself in, lays down, and then off to the next delivery, all fully autonomous. That is solving the last 50 feet. That saves 25% of the time delivering the package to your door. Thought that was a one-off and that was staged? Oh, no. The Last Feet robot, yes, it’s built to go anywhere. Here we go. We’re going to a different house, a different environment. You could even say it’s a more complex environment. Up the stairs we go. One, two, three, here we go. Through the garden, around the bend, up another step. Oh, wait, what’s that? There’s more steps. Two more. Have no fear, the robot’s autonomous and it knows where it’s going There’s the package, delivered on time, fully autonomous with no human intervention. Back to go down the stairs. There goes the robot. Oh, look at that. It can do a turn. Perhaps it thinks it’s a cool surfer. No, it’s a robot.

Through the garden it goes, back down the stairs, around the corner as it looks for its home. Its home is a delivery van. The best part about what the team Lee Redden and LastFeet are building, you do not have to retrofit the vehicle. It simply uses the preexisting vehicle. As you can see, in it goes, and away the van goes after the robot gently sits down

Well, that was impressive. I said to Lee, “Show me what the robot can do.” He said, “You wanna see sand?” I said, “Sure.” The robot goes right through the sand and through the grass. You never know what you’re gonna find at houses these days. You could find stumps like this. No stumps, no problem. The robot goes right over. The Last Feet robot is built for the last 50 feet. Logs, if you’re in the Northeast, no problem for the Last Feet robot See? Over it goes And what’s a robot demonstration without seeing man’s best friend? Yes, that’s a dog. The Last Feet robot made a friend at the park, and we’ve headed to the Stanford University campus to see what it can do. Up curbs, over telephone poles, the Last Feet robot handled it all. Rocks? No problem. Handled that, too.

Those look to be fiber installations. No problem. Power conduit going over that? No problem. The robot can handle it. You never know on a delivery what’s gonna be thrown at a robot Stairs. Easy. Here we go. One, two, three, up we go. Yay, here’s your books for school. Yay, yay, yay. Down we go. On to the next delivery it goes. Oh, wait, nope, it wants to go back up again. Forgot to deliver a book. Down complicated stairs. Even as a human, those were long stairs Now it can go right back up the stairs. No problem for the Last Feet robot Lee, what did we see today? Today you saw our last speed robot Boxer go and deliver a couple packages at people’s house here in Palo Alto, and you saw it do some off-road tricks. Yes, but we also saw it go upstairs.

That was impressive. Yes. Yeah, you saw it go up some long sets of stairs, some short sets of stairs at people’s houses and get up to their porch and gracefully bow and drop the package off. So how does Baxter do it? Is it, is it camera based, or what’s the secret sauce? It was impressive. So Boxer has cameras all around, and it sees its surroundings. And it has two downward-facing cameras that see the ground. And so it knows where to put the feet so that when a stair comes up, it sees the step and then gracefully puts the foot up, and so it can climb up and down. How did you learn how to master stairs? That was impressive. so we learn in simulation.

Lee Redden: So the robot goes through hundreds of thousands of simulations of going up and down stairs and all over all kinds of other wild terrain to learn about its own geometry, its own sensors, and how to move its body to traverse rough terrain.

Grayson Brulte: But I gotta say, this, the stairs, I know I’m saying this to you again, they were just massively impressive. I mean, what are the limitations on stairs, if any limitations? so if they are stairs that are within code, the robot can do them. So stairs aside, what problem does Last Feet solve?

Lee Redden: So Last Feet solves going from the truck or van to the door with packages to autonomously deliver them. And how big of an issue is that that needs to be fixed today? Because it seems like a lot of drivers don’t necessarily have to walk up the stairs. Yeah. So right now more and more people are having packages delivered and the LastFeet autonomous robot enables those packages to be delivered without the truck driver without the delivery person leaving the van.

Grayson Brulte: Okay. So the product works. It’s awesome watching this delivery. When does it become a business? so we’re expanding operations and we’re gonna start to take this out and start to do deliveries from our van with our robot and start to deliver packages around town. Awesome. So what would be the the first market?

Lee Redden: First market is package delivery here in Palo Alto. and then as we perfect the technology, we’ll be ready to expand to other cities. When you say perfect, first thing goes through my mind, snow. snow. Yeah. So this robot is actually gonna be extremely well-equipped for snow. four legs four wheels and four driven tires give it some really good off-road capability as you can see from some of the footage today of it going off road and going up and down sand. And so I’m excited for us to have it out in snow and start to tackle those environments, too. And what were some of the biggest challenges that you had to overcome to get where we saw today? so we have spent a ton of time getting the wheels and the legs to coordinate together along with the rest of the sensor package to be able to see the environment, perceive it, and then s- make, make smart decisions about where it goes.

Grayson Brulte: So putting this all together, what’s the future of Last Feet?

Lee Redden: The future of Last Feet is that we have gainfully employed robots that are taking packages from the truck to the door and and expanding operations.

Grayson Brulte: As you saw today, Lee Red and the team, they’re building the future of the last 50 feet of delivery. This company’s got big ambitions and big things planned. So stay tuned ’cause we’re gonna be monitoring their progress and visiting them often. The future is bright. The future is autonomous. The future is LastFeet.
