Amazon’s Vulcan robot has a sense of touch

Built on advances in robotics, engineering and physical AI, Amazon says its Vulcan robot is making its workers’ jobs easier and safer while moving orders more efficiently. And a key feature of the robot is its sense of touch.

The typical robot is “numb and dumb,” says Aaron Parness, Amazon’s director of robotics AI, especially those that work in commercial settings. “In the past, when industrial robots have unexpected contact, they either emergency stop or smash through that contact. They often don’t even know they have hit something because they cannot sense it.”

At its Delivering the Future event in Dortmund, Germany, Amazon is introducing the Vulcan robot which that is neither numb nor dumb. Built on key advances in robotics, engineering, and physical AI, Vulcan is Amazon’s first robot with a sense of touch.

“Vulcan represents a fundamental leap forward in robotics,” Parness says. “It’s not just seeing the world, it’s feeling it, enabling capabilities that were impossible for robots until now.”

And it’s already changing the way Amazon operates its fulfilment centres, helping making employee’s jobs safer and easier while moving customers’ orders more efficiently.

Vulcan is not Amazon’s first robot that can pick things up, but with its sense of touch – its ability to understand when and how it makes contact with an object – Vulcan unlocks new ways to improve our operations jobs and facilities.

Just like a human, it can manipulate objects within storage compartments to make room for whatever it’s stowing, because it knows when it makes contact and how much force it’s applying and can stop short of doing any damage. Where a human does this with opposable thumbs and fingers full of sensory receptors, Vulcan uses end of arm tooling.

In placing an object into a bin, the effector adjusts its grip strength based on the item’s size and shape, then uses built-in conveyor belts to move the item into the bin. For picking items from those compartments, Vulcan uses an arm that carries a camera and a suction cup. The camera looks at the compartment and picks out the item to be grabbed, along with the best spot to hold it by. While the suction cup grabs it, the camera watches to make sure it took the right thing and only the right thing.

With those skills, Vulcan can currently handle about three quarters of the millions of products Amazon offers. It also has the ability to identify when it can’t move a specific item, and can ask a human partner to tag in.

Amazon did all this work to improve not just efficiency, but worker safety and ergonomics. At its fulfilment centres in Spokane, Washington and Hamburg, Germany, Vulcan is already at work picking and stowing inventory in the top rows of those inventory pods. Because those rows are about eight feet up, they typically require an employee to reach them using a step ladder, a process that’s time-consuming, tiring, and one that is less ergonomic than stowing and picking at their midriff. Vulcan also handles items stowed just above the floor, so our associates can work where they’re most comfortable.

“Vulcan works alongside our employees, and the combination is better than either on their own,” says Parness.

This application of Vulcan’s capabilities is just the latest example of how Amazon thinks about and use this kind of technology. Over the past dozen years, Amazon has deployed more than 750,000 robots into its fulfilment centres, all of them designed to help employees work safely and efficiently by taking on physically taxing parts of the fulfilment process.

Meanwhile, these robots – which play a role in completing 75% of customer orders – have created hundreds of new categories of jobs at Amazon, from robotic floor monitor to onsite reliability maintenance engineers. Amazon also offers training programmes like Career Choice, which help its associates move into robotics and other high-tech fields.

Vulcan even learns from its own failures, figuring out how different objects behave when touched and steadily building up an understanding of the physical world. So, you can expect it to become smarter and more capable in the years to come.

The result, Parness says, is “a technology that three years ago seemed impossible but is now set to help transform our operations.”

That transformation is on its way not just because Vulcan’s so capable, but because Amazon implements its best work at scale. Amazon plans to deploy Vulcan systems over the next couple of years at sites throughout Europe, the United Kingdom and the United States.

“Our vision is to scale this technology across our network, enhancing operational efficiency, improving workplace safety, and supporting our employees by reducing physically demanding tasks,” Parness says. Better operational efficiency translates to getting the right product to right truck at ever faster speeds, allowing us to continue widening our selection and offer industry-leading prices.
