Today, Clearpath Robotics (best known for its rugged, ROS-friendly, and infallibly blackand yellowrobotic platforms) is announcing OTTO, a “heavy-load material transporter” that can carry a ton of stuff around warehouses, fully autonomously. Actually, “a ton of stuff” is underselling OTTO’s capabilities, since it can happily roll away with one metric ton and a half of payload: that’s a staggering 1500 kilograms (3300 pounds), or more than 22 robotics bloggers. Oof.

In addition to its enourmous payload, the key thing to know about OTTO, announced today at RoboBusiness in Santa Clara, Calif., is that it doesn’t require any infrastructure to navigate. OTTO doesn’t need barcodes on the floor (like Kiva Systems, er, Amazon Robotics warehouse robots), lights on the ceiling, beacons in the halls, RFID tags on the walls, guide dogs, interns with joysticks, or any other form of navigation devices. It’s got 20-meter lasers front and back (with an option for 50-meter range), and can localize against an existing basemap with an accuracy of about an inch. OTTO has no problem dealing with changing environments and maneuvering around inconvenient obstacles, including people (even moving ones). And if you won’t get out of its way, OTTO will use flashing LEDs and “polite” audio prompts. 

For a robot of this size (unloaded, it’s 500 kg), and with a brisk top speed of 2 m/s (4.5 mph), safety is a critical aspect of autonomy. Fully loaded, OTTO’s a total mass of 2,000 kilograms, which even when moving at low speeds represents a substantial amount of energy. So obviously, making sure OTTO is safe to work around is a priority for Clearpath, and they’re confident that they’ve got safety around humans nailed. Confident enough, in fact, that they’re already in the middle of five pilot programs. The first of those programs is in a General Electric facility, and it’s not a coincidence that GE Ventures has also just become a strategic investor in Clearpath for an undisclosed sum.

Here’s the rest of the specs that you’ve been waiting for:

Yesterday, we spoke with Matt Rendall, CEO of Clearpath, about where OTTO came from and how likely it is to flatten us if we stand in front of it.

IEEE Spectrum: How long have you been working on OTTO?

Matt Rendall: We’ve been working on OTTO for about two years. We wanted to make sure that we didn’t release the product prematurely—as we transition into an industrial category, there’s a lot less forgiveness. If you look at autonomous mining, there have been companies early to the game that released autonomous vehicles a little bit prematurely, and because of that, there have been expectations that were not met, and it sort of stagnated the industry, I think.

So what made you decide two years ago that OTTO was the thing to create?

One of the great things about the work that we’ve been doing for the last five or six years in the research market is that we get exposed to basically every application for mobile robots you can imagine, across whatever industry. What that allows us to do is gain access to a tremendous dataset, and understand competitive factors, willingness to buy, pain points, technology readiness, internal company capabilities, pretty much everything. Of all of the different industries that were pulling on us to work in research and development, materials handling was one of the strongest, and so we began to investigate that industry and try to understand the problems in that space very well, and figure out how we could shape the technology we’d been working on into a compelling product. And I think that’s what OTTO represents for us.

How does OTTO differentiate itself from other materials transport robots?

As the market has matured, we’ve seen a lot of robotics companies come up with small form factor robots, call it 200-pound or less payloads. Dealing with a heavier load is a lot more challenging because of the safety considerations and the mechanical engineering considerations. Our logic was, everything that gets shipped comes into a dock on a pallet and leaves a dock on a pallet, so our system should be very well equipped to handle a pallet. If we can do that, we’ll have the most flexibility of any robot to accommodate different use cases in different environments.

A robot this big definitely needs to be safe enough to operate around people, right?

The vehicle can move at about 2 m/s, and we do that in an industrially safe manner. We’re working to maintain compliance with industrial safety ratings; it’s a bit of a challenge in the industrial space right now because the regulatory bodies and the standards agencies really haven’t caught up to the technology yet, so we’re doing our best to understand the certification ecosystem to make sure our system is compliant for safe operation in an industrial environment in collaboration with humans.

And what’s next after OTTO? Maybe a mobile manipulator?

We’ve got a lot of experience with mobile manipulation. I think in the industrial space, you really need to release a polished product that can meet exactly the expectations that it’s promising. Mobile manipulation, in our experience, still has several years before it’s going to be able to meet the promises that it’s making, at least in an employed industrial environment where the only thing that matters is throughput, uptime, and return on investment. It’s going to be something that we continue to experiment with, but our focus right now is just straight material transport.

Clearpath may only be experimenting with mobile manipulators, but here are some interesting potential modular attachments:

OTTO is available now, and costs somewhere between free and a million dollars. We wish we could be more helpful, but Clearpath isn’t talking pricing, at least partially because OTTO has to be integrated into your existing warehouse in such a way that you can’t just buy a robot straight up. However, we were told that it does not cost more than a Grizzly, so if you bought one of those, leave us a comment so that we can at least get an order of magnitude.

Toyota’s Gill Pratt on enhancing independence in old age

By 2050, the global population aged 65 or more will be nearly double what it is today. The number of people over the age of 80 will triple, approaching half a billion. Supporting an aging population is a worldwide concern, but this demographic shift is especially pronounced in Japan, where more than a third of Japanese will be 65 or older by midcentury.

Toyota Research Institute (TRI), which was established by Toyota Motor Corp. in 2015 to explore autonomous cars, robotics, and “human amplification technologies,” has also been focusing a significant portion of its research on ways to help older people maintain their health, happiness, and independence as long as possible. While an important goal in itself, improving self-sufficiency for the elderly also reduces the amount of support they need from society more broadly. And without technological help, sustaining this population in an effective and dignified manner will grow increasingly difficult—first in Japan, but globally soon after.
